Product Description
Atlantis Single Stage 10,000 Litre Washdown Separator
The Single Stage 10000 Litre Washdown Separator is a high-capacity underground wastewater treatment system designed for gantry wash systems, HGV and truck wash facilities, quarry wheel washes and other high-flow commercial washdown applications. Engineered to separate silt, sediment, oils and hydrocarbons from contaminated wash water, it helps protect the drainage network by preventing pollutants from entering the foul drainage system.
Manufactured in the UK from high-strength rotationally moulded polyethylene (HDPE), this washdown separator combines exceptional durability with a lightweight construction for easier transportation and installation. Its shallow dig design helps minimise excavation work, making it particularly suitable for sites with restricted installation depths or higher groundwater levels.
With an impressive 10,000-litre capacity and a 100 litres per minute flow rate, this model is built to manage large volumes of contaminated wash water generated by busy commercial and industrial wash facilities. Large access openings provide easy access for routine inspection, cleaning and maintenance, helping to ensure reliable long-term performance.
How Does a Single Stage Washdown Separator Work?
Contaminated wash water enters the separator where heavier materials such as mud, grit and silt naturally settle within the chamber. Oils and hydrocarbons separate from the water and are retained inside the tank before cleaner water is discharged into the drainage system.
This simple but effective process helps reduce pollutants entering the drainage network while protecting downstream pipework from excessive sediment build-up.
