Tubosider produces bypass separators and full retention separators to achieve two levels of final discharge into the
drainage system. All our separators conform to Environment Agency PPG3 requirements for wastewater treatment.
The bypass separator (Class 1 Discharge) is designed for larger hard standing areas susceptible to hydrocarbon
spillages, which retains hydrocarbon contaminants that enter the separator in the first 10% of any storm and achieves
a final discharge
to surface water drain of less than 5mg/l oil to water.
The bypass separator (Class 2 Discharge) is as Class 1, except the final discharge is to surface or foul water drain
and is 100mg/l oil to water. The full retention separator is for more demanding applications such as fuel storage points,
plant hire equipment yards and vehicle dismantling workshops where the risk of hydrocarbon spillages is greater.
Also available to achieve both Class 1 and Class 2 discharge options, as above.
