Concrete and stainless-steel lamella plate clarifiers from Ecologix Environmental Systems treat 300 gpm. The design includes both flash and slow mixing zones before the lamella plate-settling zone. The addition of a chemical coagulant in these zones allows for extra phosphorus and turbidity removal when required. All structural and wetted components are fabricated from stainless steel, while the plates are high-density polyethylene. The conical bottom provides a solids concentration zone for efficient removal and recycling of concentrated solids via airlift pumps. A fully covered walkway above the clarifier enables easy access to the plates below. 888/326-2020; www.ecologixsystems.com.
