Wastewater Treatment Plant

The company has specialized for many years in the collection, transport and treatment of petroleum-derived waste, including oily water, industrial and other waste. To provide these services, the Company has its own specialized technical and technological potential, namely:

  • mechanical-chemical-biological treatment of oily waters and wastewater,
  • plant for disposal 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.

 

Oily water treatment plant

Our company has a modern oily water treatment plant, ensuring the quality of discharged wastewater at the level II of inland water quality. It is located in Gdańsk at 10 Kujawska Street.

 

The treatment consists of:

  • 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
  • string of 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.

 Below are some basic technical data of the new installation:

Industrial Waste Utilization Plant in Tczew

The Industrial Waste Utilization Plant in Tczew is a closely related technological facility for the Oil Wastewater Treatment Plant. The plant's task is to take in waste oils, to dehydrate them, store them and transfer them to the target recipients for further processing. The sewage and oily water produced during the process are transferred to the Purified Wastewater Treatment Plant of our Company.

 

Technical Equipment of the Department 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 alternative fuel based on adopted solid and liquid waste,
  • neutralization, through the use of waste liquor and sulfuric acid in the process.

With the required permits for the production of waste, including collection and storage, Zakład Utylizacji in Tczew extends the business profile of Przedsiębiorstwo "Comal" Sp. z o.o. for the disposal of the above-mentioned waste.
