Watermarks Projects - pre-screening

Pre-Screening is the first line of defence against gross solids. Able to filter out sediment through a rotary mesh screen, our pre-screening systems can separate contaminants from your effluent water, helping to reduce site disruption and avoid high fines from wastewater regulators.

Our Pre-Screening Products:

  • Can load up to 35,000 litres per hour
  • Option for base tank or high level mount

Our rotary drum pre-screens aim to remove solids from effluent water. This process begins when the wastewater enters the horizontal cylinder where the durable mesh screen is found. This screen is in effect, a cylindrical drum screen that can rotate at varied speeds, filtering solids at a controlled rate. 

Solids filtered out by the screen will enter a separate outlet leading into a sediment collection point. The clarified water will then carry on through the tank, and is pumped out into further treatment systems where necessary.
