ENV21 - Model V2B1 - Stormwater Treatment System - Brochure

The “V2B1” is the flagship of environment 21.  Its unique standard pre-cast concrete two manhole design allows it to help you meet the EPA goal of 80% TSS removal efficiency. The inlet manhole has a tangential mounted inlet pipe that creates a swirl flow pattern, which improves flow distribution and reduces turbulence, thus enhancing sedimentation settling.  Proper sizing essentially offers a complete removal of sandy sediment. The environment 21 `Center Withdrawal Elbow Pipe` conveys flow to the outlet manhole where floatable debris is retained by using an underflow baffle. And, as with all environment 21 products, maintenance is a cinch with access openings to all stages and a clear view to the sump. The V2B1 is ideal for unique site scenarios with other utilities.
