The SDD3 by NEXT Stormwater Solutions is an enhanced hydrodynamic separator which uses a twin vortex design along with gravitational and centrifugal forces to effectively remove sediments (TSS), floatables and oil from surface runoff. The removal of other harmful pollutants such as N, P, Pb, Cu, Zn, which are commonly found in stormwater runoff, will also occur as these pollutants naturally couple themselves to suspended solids. As a result, the SDD provides increased protection for the receiving waters as well as any downstream process.
Superior performance is guaranteed as the SDD offers an exceptional surface loading rate.
The SDD3 was developed by NEXT Stormwater Solutions in collaboration with the Polytechnic University in Montreal. Laboratory testing was performed by the Centre des technologies des eaux (C.T.E).
The performance of the SDD3 has been verified by the Environmental Technology Verification (ETV) program and has been successfully laboratory tested according the NJDEP 2013 testing protocol.
