Wastewater Treatment Plant


The main spectrum of the Company's activity in the environmental protection spectrum receiving, transport and disposal of:

  • oil-derived waste, including oily water;
  • ballast water, bilge water, slops, sludges and other wastes of various origins coming from vessels;
  • drilling wastewater;
  • ndustrial waste of various origins, including factories, sewage treatment plants, slaughterhouses;
  • wastewater after tanks and installations cleaning;
  • sludges, including oily sluges;
  • oily grounds, aggregates;
  • and many other according to the premits.


Wastewater Treatment Plant

We have a modern oily water treatment plant, ensuring the quality of discharged wastewater at the level II of the inland water purity class, located at 10 Kujawska Street in Gdańsk. The Utilization of Industrial Wastes in Tczew is a closely related technological base.


The wastewater treatment plant includes:

  • a mechanical cleaning sequence with an electrostatic precipitator and a four-stage gravity separator,
  • chemical cleaning process with a two-stage mechanical and pressure flotation system,
  • biological treatment with activated sludge.

In order to obtain a very high degree of pollution reduction, an additional supplement to the applied technology of purification of oily waters is ozonation of treated wastewater.


The technical equipment of the Plant in Tczew also allows:

  • dewatering and sedimentation of sediments, including oily sediments from external recipients, as well as from the technological process of the Oil Wastewater Treatment Plant in Gdańsk,
  • distribution and dehydration of oil-water emulsions,
  • rinsing oily soil, aggregates,
  • preparation of an alternative fuel based on solid and liquid waste accepted,
  • neutralization, through the use of waste liquor and sulfuric acid in the process.

Technical and technological potential

To carry out these services of collection, transport and waste management, the Company has its own specialized technical and technological potential, namely:

  • mechanical-chemical-biological treatment of oily waters and wastewater,
  • plant for utilization of used oils and biodegradation of soils contaminated with oil derivatives,
  • barges with a capacity from 100 to 1350 m³, adapted for the transport and storage of liquid hazardous waste,
  • a team of Man-type, Volvo, and semi-trailer truck tractors, adapted to carry hazardous materials in accordance with ADR requirements.

Fulfilling the requirements of the Waste Act of 27 April 2001 and executive acts to it, our company deals with the recovery of waste oils from collected waste, using the best available technologies (BAT). Oils after pre-treatment are transferred, among others, to plants such as Rafineria Nafty Jedlicze, to be recycled.Spełniając wymogi Ustawy o odpadach z dnia 27 kwietnia 2001 r. oraz aktów wykonawczych do niej, nasze Przedsiębiorstwo zajmuje się odzyskiem olejów odpadowych z odbieranych odpadów, stosując najlepsze dostępne technologie (BAT).
