Global Water’s EcoTreat Class 1 Bypass Separator is an in-line device designed to treat stormwater run-off from paved areas where low levels of hydrocarbon residuals and gross pollutants are present whilst allowing high flows to pass without restriction. The Bypass Separator is suitable for primary and secondary treatment in low risk areas, removing hydrocarbons and suspended solids whilst preventing on-site flooding from storm events.
|Treatment flow rate (L/s)||7||12||25|
|Bypass flow rate (L/s)||35||60||125|
|Inlet diameter (mm)||160-315||200-400||315-355|
|Outlet diameter (mm)||160-315||200-400||315-355|
|Oil storage volume (L)||70||120||250|
|Sediment storage volume (L)||700||1200||2000|
Note: The treatment flow rate depicts the maximum flow the EcoTreat Class 1 Bypass Separator can treat through the coalescing unit, while the bypass flow rate is the maximum rate at which partially treated flow moves through the unit in a storm event.

Full-scale performance testing of the EcoTreat Class 1 Bypass Separator was conducted by the University of South Australia in accordance with Stormwater Australia guidelines for suspended solids and nutrient removal. The unit achieved Class 1 gravity supply device requirements, in accordance with EN 858-1.

SOLIDS SEPARATION CHAMBER
All incoming first-flush run-off passes through the settling chamber, allowing settling and removal of sediment and other suspended solids.
OIL SEPARATION/STORAGE CHAMBER
Captured oil and other hydrocarbons are held in the oil storage chamber. The capacity of this chamber meets the requirements of EN 858-1.
COALESCING TREATMENT DEVICE
The flow then passes through the coalescing treatment device which combines small droplets of light liquids such as oil and diesel, allowing them to be trapped and removed, ensuring the oil content in the outflow is less than 5 mg/L. This meets the requirements of a Class 1 gravity supply device, in accordance with EN 858-1.
During high-flow events, the excess flow bypasses the settling chamber and the coalescing device, ensuring that trapped pollutants are not diluted or washed through. This bypass feature ensures that the site is protected from flooding in storm events.
