PLANTS FOR PURIFICATION OF WASTE WATERS - BIO PUR               Bio-pur-plant-for-purification-waste-water

Krušik-plastika Osečina and Ekolog Doo Belgrade build together plants for purification of waste waters


In areas, places and parts of settlements which are located far away from urban infrastructure and sewage systems, so that waste water is discharged directly into the natural recipient. BIO PUR device is usable for: households, cottages, camps, hotels, catering facilities, schools, factories, villages, smaller settlements …


BIO PUR device works by biodegradable principle using „Floating bed“ technology. Water flow through the device is gravitational, without the use of pumps, or any other movable elements. Thanks to this it is provided a backflow into the facility during power outages.

Wastewaters from the facility, enter the first part of the wastewater purification plant, where it takes the preliminary sedimentation and separation of larger waste which blocks the passage of the further purification step. The next stage of purification is biological degradation of organic matter, which operates a system of deep aeration. It has intensified by the "floating bed" system of floating biofilm carrier. The next stage is aerobic stabilization and deposition of mineralized sludge. Activated sludge from this phase is mixed with the precipitated material from the preliminary phase deposition and prevents the occurrence of of unpleasant smells. Finally thus purified and clarified water goes into the final chamber where they played two final phases of the treatment - adsorption filtration and disinfection. Thus purified water is high quality and it can be discharged into the open watercourse.




Construction and installation of plants for purification of wastewater

waste-water-bio-purBIO PUR device is compact design. It is made of high density polyethylene (HDPE). The product is produced by spiral winding technology that enables maximum dimensional stability prior to burial. This material has multiple advantages compared to the other:

  • Chemical resistant to most of the chemical agressive substances
  • Resistant to abrasion, corrosion and electro stable
  • Thermo resistant (-30 ° C to + 80 ° C)
  • Durability, prolonged exposure to atmospheric conditions do not affect the functionality of the device (service life up to 50 years)
  • Does not pollute environment or content inside the device, preventing the development of algae and bacteria
  • UV stable
  • Easy to maintain


BIO PUR is mounted on a subgrade of compacted sand. For special conditions and vertical housing it is necessary to set the device to the prepared foundation slab
