Mechanical Screens

  • Applications
  • Municipal and industrial wastewater treatmentplants
  • Pump stations
  • Surface water intake structures
  • Combined sewer overflows
  • Benefits
  • Sturdy stainless steel design
  • Drive and all bearings above water
  • Reliable operation, low maintenance
  • High flow rates, low head loss
  • Easy to clean

Step Screen


Coarse and fine wastes retained by the grids still contain water. Grid principles developed to reduce water contents and volumes simply work; The solid wastes kept in the grates are conveyed by conveyor or poured directly from the grill milk to the grill press. The spiral inside the grill press drags the grate waste to the outlet. The required pressure is provided by the weight and friction of the solids accumulated in the discharge pipe. Meanwhile, the filtered water is poured into the drip pan through the drainage holes and discharged therefrom.

Basket Screen

Small-scale water treatment plants to reduce their investment costs and is used to save space is a type of grill. Basket screen, wall-mounted cradle system moves the desired distance. Will create problems so that the difference in elevation is eliminated. Waste water, basket screen contains solids passing through the grid could be kept in baskets. Wastewater, depending on the amount of solids that came with the cradle system is cleaned by pulling up. BIOLAND TREATMENT basket screen as a standard stainless steel and optional cases dip galvanized or epoxy coated carbon steel is manufactured.

Spiral Channel Screen

This is a type of fine screen that can be used especially in open channels with narrow width. This type of screen can be utilised in domestic and industrial wastewater treatment plants, water treatment plants, and process water preparation plants for various industriesa. It consists of a cylindrical screen and a spiral that cleans it. It can be positioned at an angle of 30-50 depending on the wastewater channel or the location where it will operate. The screen can be manufactured in perforatedor wedge-wire models. Screenings accumulated on the screen during flow are pressed and discharged, like in screw conveyors. It can be operated in time-controlled, evelcontrolled, or both time- and levelcontrolled mode.

  • Blockage-free base step without plastic shoe
  • Better incoming flow to the screen panel
  • The machine is installed directly on the channel
  • A rugged frame construction with modular
  • An extremely stable eccentric drive system
  • An extremely stable eccentric drive system
  • An electrical overload protection
  • Equipped with a heavy-duty geared motor
  • An excellent price/performance ratio

Static Screen 

Static screens are used to remove solids from waste water ; hence they reduce the solid load to other treatment stages and protect mechanical parts in those proceses. Main difference between static screens from other ar screens is much smaller bar spacing. It is possible to strain waste water mre effectivelly with 0,25mm openings. As the size of removed particles get smaller, it becomes more important to continously clean the screen surface. Energy of incoming wastewater is utilised to clean screen surface for static screen.
