Rocla First Defense High Capacity (HC) separator

Wednesday, 21 March, 2018 | Supplied by: Rocla


Rocla has introduced the First Defense High Capacity (HC) separator for effective stormwater treatment. The TSS capture device has been designed with flexibility in mind and to maximise available site space without compromising the treatment level.

With internal components designed to remove and retain gross debris, total suspended solids (TSS) and hydrocarbons, the device prevents pollutant washout at peak flows to ensure high efficiency. It is an adaptable online treatment system so it works easily with large pipes, multiple inlet pipes and inlet grates, and now also contains a high-capacity bypass for the conveyance of large peak flows.

There is a long flow path through the device that ensures extended residence time within the treatment chamber and enhances the pollutant settling. All higher flows bypass the treatment chamber to prevent turbulence and washout of any captured pollutants, protecting the surrounding environment.

The device has a retrofit installation that means stormwater treatment can be placed on, or tied into, an existing stormwater line. It is suitable for sites constrained by space, topography or draining profiles with limited slope and depth of cover. It is delivered to the site pre-assembled and ready for installation.
