From Stormwater Products
The 'UniScreen', available in vault or manhole, uses a multi-function insert which: traps solids greater than 250um, floatable debris and hydrocarbons, acts as a flow diffuser/distributor, helping to meet the EPA goals of gross pollution removal. Also the unique shape improves scouring of the inlet side screen surface thereby minimizing potential obstruction and maintenance. The entire floor area is available for sediment storage and is easily accessible for inspection and cleaning. Ideal UniScreen applications include pre or post treatment to a detention pond where there is a need for treatment, but not to the level of filtration products.
