CDS – Continuous Deflective Separator

The CDS hydrodynamic separator is a unique hybrid technology that employs swirl concentration and inertial based screening to effectively separate suspended solids, hydrocarbons and trash from stormwater runoff. In a process called, “Continuous Deflective Separation” the power of the incoming flow is harnessed to shear stormwater pollutants off the screen and deflect them to the centre of the separation chamber where they fall to the storage sump or are trapped at the water surface for later removal.

There are over 40,000 CDS installations worldwide with units treating flows from 10 l/s to 5,000 l/s. With this range of capability, the CDS is a premier technology for underground storage and low impact development (LID) pre-treatment as well as treatment of large municipal draining systems.
