The sand separator is usually at the very beginning of wastewater treatment and offers a decisive advantage when used before a DAF process:

It effectively removes sand, glass, aluminum, PET and other rough solids from wastewater.


The removal of all coarse and rapidly sinking particles protects the subsequent process chain. In this way, we reduce pump and valve wear and also create significant benefits for the subsequent flotation process.

First-class product features

Water recycling — pre-purification is decisive

raindrop icon
Plant protection
The sand separator removes abrasive particles that could otherwise damage pumps and valves.
raindrop icon
Improving efficiencies
Sand and heavy particles can interfere with the flotation process by hindering the formation and ascent of air bubble-solid aggregates.
raindrop icon
Reducing stress
As a result, less material has to be separated by flotation, which reduces energy consumption and the use of chemicals in the DAF process.
raindrop icon
Stable DAF process
The pre-removal of solids enables precise dosing of the process chemicals in the DAF process, thus reducing costs and stabilizing the process.
