Limited capacity under rising flows

When flows rise, conventional primary clarifiers and screens have trouble keeping up, which results in bottlenecks and expensive plant extensions. Without constructing more tanks, you must take a pre-treatment step that frees up space in the biological stage.

Reusing wastewater

You wish to remove suspended particles from contaminated water streams so they can be used again.

Cost reduction

Wastewater treatment can be very expensive, but you need to keep costs low. The subsequent stages of treatment are more economical when suspended particles are eliminated from sewage or industrial effluent.

High energy use and carbon footprint

One of the biggest energy users on the property is aeration. An excessive solids load raises running expenses and blower demand. The quickest method to lower energy use and CO2 emissions is to cut that load upstream.

How does it work ?

Our process

Feed water enters the enclosed stainless-steel frame and flows onto a continually moving filter belt (90-2000 µm). As a thin cake builds, it acts as a dynamic pre-coat that sharpens separation efficiency. Belt speed automatically adjusts to water level. The filtrate (free water) passes through the mesh; captured solids travel upward, dewater by gravity, and are released by a gentle air blow-off into a discharge hopper. A cyclic hot-water rinse removes grease to keep pore openings from the filter mesh clean.

The sieve part (sieve table) of each Intensieve® can be removed easily and placed in a frame. Among other things, the filter frame is raised out of the frame to replace the sieve cloths.

Modular units (CT-80 to CT-170) can be combined to treat 5 - 50000 m₃/h and are available as plug-and-play skids for pilot or permanent use.
