With no moving parts, the JDS is a hydrodynamic separator that is able to screen trash and debris, including floatables and both neutrally and negatively buoyant materials, from stormwater runoff without blocking the screen. Built with durable precast concrete, the JDS hydrodynamic separator also captures total suspended solids (TSS), oil, grease, and other total petroleum hydrocarbon pollutants. Captured pollutants are retained without scouring, even under high flow bypass conditions. Capable of treating flows from 0.7 to 72 cubic feet per second, the JDS Hydrodynamic Separator is certified and approved by various agencies.
