STEKON waste water treatment facilities

  • Water legislation of the Russian Federation bans dumping drainfall and snowmelt waters which are drained from habitable territories and manufacturing sites and has not been purified to established quality targets to water catchment areas. Treatment facilities for surface-water flow ensures purification of waste waters to necessary regulatory values and prevent pollution of environment with various naturally occurring and industry-related impurities.


    A system is selected upon the following criteria:

    • concentration of pollutions on the inlet to the system (suspended materials and petroleum products)

    • performance

    • required degree of purification (discharge point of purified waste stream)

    • selected type of system (accumulating vessel, modularity)

    • depth at which accumulator is imbedded

    Concentration of pollutions on the inlet:

    • Suspended materials up to 4000 mg/l

    • Petroleum products up to 500 mg/l.

    Degree of purifying conforms to regulated values of dumping to fishery pools:

    • Suspended materials up to 3 mg/l

    • Petroleum products up to 0,05 mg/l.

    Both single-body and modular-type (as separate bodies) versions of STEKON stormwater treatment facilities can be supplied.

    Integral elements:

    • Sand separator

    • Oil-and-petrol separator

    • Sorption filter

    • Distribution well

  • Performance

  • Waste waters treatment facilities are used in rain-water drainage systems for purifying storm/rain petroleum- and oil-containing surface water flows coming from habitable areas, motorroads, gas stations, car parkings and garages, as well as from residential homes and public amenities.

    Composition of an over-the-surface flow which undergoes purification at waste water treatment facilities is regulated with regulatory-technical documents adopted when designing and calculating basic technical parameters of purifying facilities: СП 32.13330.2012. Recommended guidelines on considering requirements to protection of environment when designing motorroads and bridge crossings.

    The facilities may be of various heights and diameters and rigged with process equipment (pumps, UV-sanification facilities, slurry decantation facilities) and utility systems (exhaust ventilation, heating systems), instrumentation and controls upon agreeing with a customer.

  • Advantages

    • The treatment facilities are released from factory in in a maximally prefabricated state.

    • The body is made of reinforced fiberglass, a light and durable, not corrosion prone material

    • Underground installation

    • Performance of a treatment plant is 10 – 150 l/s. Higher-performance systems consist of several lines of treatment facilities.

    • Self-sufficiency (no need for electroenergy supply)
