Preliminary treatment units are located at the entrance of wastewater treatment facilities. They reduce the pollution load of the wastewater treatment plant, prevent the accumulation of oil and solid wastes in the system, extend the life of the equipment and increase the efficiency of the wastewater treatment system.

F Physical / Pre-treatment units consist of treatment stages without any chemical addition, such as separation of coarse materials from wastewater from water, flow measurement and flow adjustment. Floating (e.g. oil, grease, fiber, sawdust, plastic etc.) or precipitating substances (e.g. stone, sand, metal, etc.) in the wastewater are separated from the water by physical treatment methods.

  • Adjustable / Floating Sluice
  • Penstocks
  • Stoplog
  • Telescopic Valve
  • Basket Screen
  • Spiral Screen
  • Linear Channel Screen
  • Channel Circular Screen
  • Rotating Disc Sieve (Discostrainer)
  • Drum Screen
  • Static Screen
  • Perforated Screen
  • Plastic Conveyor Screen
  • In-Channel Micron Screen
  • Screening Presses And Conveyors
  • Microflotation DAF
  • Sand Separator


AVEKON Compact Pre-Treatment System is a compact treatment system including screening and precipitation sections. In the first stage, the solid materials held in the screen are separated from the wastewater. In the second stage, the wastewater is taken to the sedimentation section where the collapsible / floating materials are separated from the wastewater. The materials deposited on the surface and settled to the bottom are taken with scrapers and auger spirals and taken to waste container automatically. Since the wastes kept in the system are cleaned continuously, the efficiency of treatment is high and the space requirement is low. Since the shaftless auger structure prevents jams and blockages, the collected waste is easily transported and disposed of. Additional sludge dewatering systems may be added if necessary. If there is oil in the wastewater, an optional blower is added.

AVEKON Compact Pre-Treatment System is designed to treat wastewater of various capacities and different character.
