SEPARATORS, FILTER BASKETS, WATERWATER PLANTS,
Separator of petroleum substances - necessary for most companies and institutions with paved areas on which vehicles and working machines move. It is not uncommon for uncontrolled leaks of fuel, oil or refrigerant substances to occur there, which, by penetrating into the soil and waters, may cause their contamination with petroleum substances. Such accidents may not only be dangerous for the natural environment, but the consequences of their occurrence may also prove costly for the land manager. For prevention purposes, separators and settling tanks are used to clean the wastewater before it reaches the receiver.
Petroleum substances separator.- What is it?
A separator of petroleum substances is a device installed in rainwater drainage systems, designed to separate petroleum pollutants from the rest of the sewage (more precisely, separating oily parts from water).
Separators use flow systems, where lighter and heavier chemical compounds (substances) are separated from water.
Usually, in the first stage, the sewage goes to the settling tank, where the accumulated suspension remains and sinks to the bottom. In the second stage, the wastewater flows to the separation chamber, where the proper (main) treatment process takes place.
Separator of petroleum substances. - In what cases are separators used?
The main application of the separator of petroleum substances is primarily in the treatment of rainwater and meltwater from polluted surfaces of hardened areas, e.g. urban areas, gas stations, fuel depots, parking lots, industrial plant areas, but also parking areas, office buildings, warehouses and shopping centers.
Separator of petroleum substances and compliance with the quality requirements of discharged wastewater
Thanks to the use of a separator, the discharged rainwater and snowmelt will meet the requirements set out in the law, as long as it is cleaned and serviced frequently enough.
Petroleum substances separator. - Does it require a water law permit?
The installation of the separator in the sewage system does not require a water law permit, but the device should be described in the water law report when applying for a water law permit for the discharge of rainwater and snowmelt into the environment (into waters or into the ground).
Petroleum substances separator. - Types of separators and their location. - What are separators made of?
Separators can be distinguished depending on the place of planned foundation:
- in green areas, e.g. lawns, meadows, separators made of plastic are usually installed,
- in the inrun area (on which vehicles or working machines move), concrete separators or plastic separators with an additional concrete slab are installed, which is designed to spread the pressure of passing vehicles and machines in order to prevent damage to the device itself.
Petroleum substances separator. - How to choose a separator? – What important information is needed to select a separator?
In order to determine the basic value that is separator size The most important information you should know is:
- the size of the area from which rainwater and snowmelt will be discharged (the so-called catchment area);
- specifying the planned location of the separator's foundation. - It is about later specifying the weather conditions prevailing in a given area regarding the amount of precipitation (mainly the amount of storm flow) and the topography of the land. By specifying the location of the plot along with the precinct and plot number, the specialist should be able to check this information on his own;
- the amount of suspension present in the rainwater;
- scale of protection of surface waters in the vicinity.
In order to select additional parts for the installation of the separator, it is important to have the following information:
- about the depth of the foundation of the rainwater drainage system in the place of the planned foundation of the separator;
- of the diameter of the sewage pipes at the inlet to the separator and the outlet from the separator.
- It is also important to choose the right place for placing the separator. Often, the final location of the separator results from the course of the rainwater drainage system and the slope of the surface.
Petroleum substances separator - service and cleaning of the separator
In the documentation separator the recommended frequency of inspection and cleaning/replacement of the separator cartridge is most often indicated.
The correct selection of the separator and its use (maintenance and cleaning) ensure proper sewage treatment, i.e. effective removal of substances that we want to get rid of from sewage.
Failure to service and clean the separator (with the frequency specified in the device documentation) may void the device warranty.
Separator of petroleum substances - types of devices
- Separators with a lamella insert are best suited for use in larger catchments, e.g. in the field of water drainage from large parking areas.
- Separators with a coalescing cartridge are more often used in smaller catchments or where pollutants have low concentrations (areas of medium and small parking lots).
However, each case is different. Our specialists analyze separately and help in selecting the device for the existing conditions as well as the condition and composition of wastewater. If you are interested, please contact us.

Petroleum substances separator. – What is the operating principle of the separator?
Separation of solid impurities (such as sand, gravel, earth) with settler mostly sandbox. The process of sedimentation is used here (gravitational settling of solid fractions that accumulate at the bottom of the settling tank).
Sewage flows into chambersin which it occurs separation process. Thanks to the special filters installed there, the particles of petroleum substances separate from the water and then accumulate (accumulate).
What does that mean exactly? – At this stage, water (still polluted) passes through a system of filters, e.g. coalescing filters, which are to lead to the flow of oil-derived pollutants from the sewage mixture to their surface. Particles accumulate on the surface to form clusters.
In the last phase of treatment, the wastewater leaves the Separator device through the drain. They can both go to the rainwater drainage system and, alternatively, to a drainage ditch or other receiver. The drain can be equipped with a device for automatic closing, e.g. a float. This solution closes the tank when the tank is overfilled with petroleum substances accumulated there. Some of the devices for automatic closing have sensors informing about the closing of the separator outflow.
Petroleum substances separator. - What is bypass?
Separators are most often offered with a by-pass. The by-pass system is designed to divert excessive amounts of rainwater or snowmelt through a bypass in the event of higher flows, e.g. during heavy rains. Thanks to this, the incoming very large amounts of rainwater do not interfere with the operation of the separator, which prevents the destruction of the internal structures of the device and the uncoordinated discharge of polluted waters to the surface.
More precisely: Bypasses are separator elements that are used to pass water outside the separator cartridge in order to prevent its destruction when the amount of water flowing into the separator is greater than its assumed capacity. In this case, the water is often directed over the cleaning cartridge, protecting the separator from damage.
In some cases, by-passes are not used.
Petroleum substances separator - additional solutions for underground garages
Separators in the case of underground garages very often have an additional drainage pump, forcing the water flow towards the surface of the ground (up).
Cassette system
The cassette system is perfect for both the modernization of existing oil separators and the design of new separators.
Filter baskets
Filter baskets are often the only product to be used in cases of complex construction of sewage disposal systems.
Filter basket. - In what cases does it apply?
It is requested that one of the sewage outlets is located far from the oil derivatives separator at a distance which, from the economic point of view, creates excessive investment costs for the company. In such cases, in order to temporarily protect the environment, until the installation reconstruction investment is made, filter baskets are used placed in the manhole / wells, from which wastewater does not go to the separator of petroleum substances.
Filter basket. - What is this ?
The filter basket is a new and effective method of effective treatment of wastewater flowing into the rainwater drainage system by using the sorbent in replaceable filtering devices placed in sewage manholes.
The easy-to-replace filter cartridge is placed in a stainless steel basket.
Filter basket. - How it works?
The filter basket is used to treat wastewater flowing into the rainwater drainage system. Most often, it is placed in sewage wells, to which pollutants along with rainwater and snowmelt are discharged.
The filter basket is suspended to the control plate, which is placed under the grate (grid) of the sewage chamber. The advantage of the installation is the ease of absorbing pollutants, in particular: petroleum hydrocarbons, oils, heavy metals, some acids and bases. We achieve this by using a sorbent placed in a replaceable filter cartridge in the basket.
Filter basket. - How often is the filter cartridge replaced?
Under normal operating conditions, the filter cartridge in the basket is replaced 2 to 3 times a year by a service company.
When replacing the sorbent in the filter basket, the company should take the used filter cartridge and hand it over as waste, in accordance with applicable regulations, to an authorized plant managing such types of waste.
The material used for production is usually stainless, acid-resistant sheet.

Treatment plants
- INDUSTRIAL WASTEWATER
Container sewage treatment plants. - How to treat industrial wastewater?
Container sewage treatment plants are usually used commercially in economic activities. They are used both by industrial plants and other institutions, e.g. by kindergartens and smaller companies, not necessarily production ones.
Wastewater from industrial or catering installations is more challenging to treat than wastewater from single-family homes, multi-family homes or even housing estates. This is due to higher concentrations of detergents and chemicals.
Our company offers various solutions that are able to solve various problems and cope with even the most demanding needs.
The treatment plants we offer have high efficiency and competitive prices.
Wastewater treatment plants - industrial wastewater, domestic wastewater, rainwater - definition
Industrial sewage is wastewater that is neither domestic nor rainwaterarising in connection with the plant's commercial, industrial, storage, transport or service activities, as well as their mixture with sewage of another entity, discharged through the sewage system of this plant. Their chemical composition depends on the production profile, the industry of the company, the technologies used in the plant and the method of wastewater treatment.
Industrial wastewater is divided into:
- Degradable - undergoing chemical changes, as a result of which non-toxic substances are formed,
- Non-degradable - durable, e.g. DDT, heavy metal compounds and others.
Domestic sewage: Sewage generated from single-family and multi-family residential buildings and public utility buildings, arising as a result of metabolism or functioning of households, and sewage similar in composition to those from households.
Rainwater: rainwater and/ or snowmelt included in sewage systems (regardless of whether they are open or closed), coming from contaminated surfaces with a permanent surface, e.g. from transport bases, from roads and car parks, from cities, from ports, from airports, from industrial, commercial, service and storage areas.
Industrial treatment plant. – Is it needed? Who needs it?
The industrial treatment plant is intended for companies and enterprises representing various industries. In this respect, our company supports not only the industry, trade and services, but also various types of institutions. The rapid economic boom in Poland brings both opportunities and threats. One of the threats is the possibility of using up natural resources and destroying the natural environment. This can be counteracted in various ways, including: introducing various solutions such as the industrial wastewater treatment plants we propose.
Industrial treatment plant. – Is it worth investing in an industrial treatment plant?
All industrial wastewater should be treated before being discharged into the environment. Contact of plants, animals and humans with untreated sewage may pose a threat to the health and even life of these organisms.
An investment in a sewage treatment plant creates not only ecological but also financial benefits. It reduces the costs associated with the discharge of pollutants. An industrial sewage treatment plant creates the opportunity to reduce the costs associated with the discharge of pollutants.
It is very important to equip entities whose wastewater is heavily polluted with a sewage treatment plant. The critical point where we should take care of the installation of sewage treatment plants is the food industry, catering establishments, hotels and holiday resorts. Equally important industries are chemical, pharmaceutical and cosmetic production, as well as other industries where a lot of chemical substances are used.
Our company offers various types of treatment plants. If necessary, we will send our proposal, and if necessary, we will also provide advice.

Household sewage treatment plants. – Is it worth it?
If you need a household sewage treatment plant for your household - you've come to the right place. If you are building a new house, the treatment plants we offer are a very good investment. If you want to replace today's septic tank with a sewage treatment plant. In addition to comfort (this is a more convenient solution) and safety, you gain economically, and in addition, the natural environment gains thanks to you.
Household sewage treatment plants. – Who are they for?
They are intended for the treatment of household sewage or sewage of a similar composition when there is no access to the municipal or communal sewage system.
Such a treatment plant should meet the requirements for energy efficiency and carbon dioxide emissions.
We offer comprehensive solutions in the field of sewage treatment plants for:
- large residential buildings;
- enterprises;
- recreation centers.
Before you make your final decision, learn how it works and the rules for using a home sewage treatment plant!
Household sewage treatment plants - the solution to your problem!
It is the key to success when it comes to wastewater management for households located in areas where no sewage system has been installed yet.
It is clear that if you are able to connect to the sewage network, you will not have to commission the construction of a household sewage treatment plant. (By law, if your home is located near a sewerage system, it should be connected to it.)
What if it's different?
It's not always "as beautiful as we want". There may be a situation when such a network does not run in the vicinity or close enough to our plot. In this case, you are forced to make a decision, choosing a septic tank installation, although it seems antediluvian, or an ecological sewage treatment plant installation.
When weighing the pros and cons, you have to make a final decision that seems simple, but sometimes there is a lack of conviction. What to choose to be the best for you???
Call us - a specialist will try to advise you - present both solutions - and you will make your own decision.
Household sewage treatment plant or septic tank? - What to choose?
The most important aspect for many people is the economic aspect - the cost!
An investment in a treatment plant at the initial stage obviously seems more expensive than the purchase, foundation and connection of a septic tank.
Building a sewage treatment plant is much more expensive than a septic tank, but the subsequent maintenance of a septic tank is significantly more expensive than the maintenance of a sewage treatment plant.
After a few years from the investment in treatment plants, the costs pay off, and the balance of benefits shifts to the scales of the treatment plant.
Household Sewage Treatment Plant. – Can I get a grant?
Household sewage treatment plants are pro-ecological investments. Such investments have recently been supported by the European Union, which allocates significant resources to support them. The investor, deciding on such a solution, commits his funds. However, it is possible to reduce own expenditure by applying for the remaining part of the amount that can be obtained from the Environmental Protection and Water Management Fund or the European Union structural funds.
Household Sewage Treatment Plant. – Is it possible to recover the water?
Climate changes that occur on earth in the form of progressive warming are the most topical topic. In addition, the deteriorating environmental conditions and pollution within the hydrosphere and lithosphere. Currently, local droughts that threaten ecological disasters are a very significant problem.
A panacea may be an investment, a good design and proper construction of a biological treatment plant, for the installation of which you can also apply for funding.
There are mechanisms for the operation of a biological treatment plant, thanks to which we have the opportunity to recover water.
The installation makes it possible to purify the sewage to the second class of water purity, which allows for its reuse.
An investor who decides to install a biological treatment plant may also apply for subsidies from the commune office or the Fund for Environmental Protection and Water Management.
By choosing this solution, we not only protect the environment, but also have a chance to save a lot.
Household Sewage Treatment Plant. – What are the formalities to be fulfilled?
The conditions specified in the Local Spatial Development Plan (so-called LZP) are important.
In an area without a sewage system, it should be checked whether such a document exists, and if so, get acquainted with it, while checking whether it is planned to connect to the sewage system in the near future? On this basis, you can decide which solution to choose.
In the absence of an LZP, the Study of Conditions and Directions of Spatial Development (so-called SUiKZP) may be adopted - such an earlier preliminary plan before the adoption of the LZP, including records of the officials' intentions regarding the future content of the LZP. However, the final appearance of the Local Plan may differ from the scope of the Study.
Local ordinances most often do not allow the location of household sewage treatment plants in protected areas where there is a risk of flooding or flooding with rainwater.
Household Sewage Treatment Plant. – When are permits needed (building permit, water law permit)?
Water permit necessary is when the amount of treated sewage discharged into waters or land from the farm to the treatment plant is greater than 5 mXNUMX3 per day.
Amount of sewage X > 5 m3/day
A lower capacity of the treatment plant does not require a water law permit.
(Articles 33, 34, 389 of the Water Law).
Building permit needed is when the capacity of the treatment plant is from 7,5 m3/day.
The capacity of the treatment plant X >= 7,5 m3/day
Treatment plants with lower capacity only require notification.
(Article 29, section 1, point 5 of the Construction Law).
The application is submitted to the commune or city office competent for the location of the investment.
In due time before the commencement of construction works, the intention to carry them out should be reported to the Department of Architecture and Construction, and the completion of the works should be reported to the Office.
It is good to prepare a sewage treatment plant design that includes the sewage treatment method, adapted to the conditions on the plot, containing the parameters of the sewage treatment plant in accordance with the needs of the household.
Sewage treatment plant. – When to plan construction?
If a sewage treatment plant is planned, it is determined by weather and ground conditions.
In order to efficiently carry out the construction, it is necessary to check the ground conditions on the plot and the weather conditions. Work should be planned for the period from spring to autumn to avoid freezing of the ground, which may make work impossible or, at best, more difficult.
When planning the completion of works, it should be borne in mind that it would be ideal for the household to be occupied (in the case of a house construction project), because the operation of some of the treatment plants is conditioned by sewage loads, some require a certain period of time to achieve full effectiveness.
Sewage treatment plant. – How to choose a place for a sewage treatment plant on the plot?
It is important that the settling tank is placed in the ground as close to the house as possible.
- Venting the settling tank is equally important. (outlet - vent outlet should be at least 0,6 m above the upper edge of the window opening, and the ventilation outlet should have a minimum diameter of d = 110 mm. If adequate venting is not provided, the settling tank should be moved away from the house approx. 5m.
(§ 37; § 38 Ordinance on technical conditions to be met by buildings and their location)
- If we are just planning or designing a house and sewage treatment plants already at the planning stage, we should locate the sewage treatment plant on the land development plan in such a way that the sewage pipe leaves the building in the direction of the planned foundation of the sewage treatment plant. The closer location of the house to the settling tank will ensure a higher temperature of the sewage reaching it, thus increasing the intensity of the decomposition taking place.
- Appropriate distances from certain devices, media, buildings and borders should also be maintained:
– from the well,
– from water and gas pipes,
– from power cables,
– from the border of the plot and the road,
– from the trees.
(§ 36; § 31., Regulation on technical conditions to be met by buildings and their location)
Law basics
Regulations:
– on the technical conditions to be met by buildings and their location.
– on the technical conditions to be met by telecommunications building facilities and their location.
