Secondary treatment

The HumeCeptor® hydrodynamic separator is specifically designed to remove hydrocarbons and fine suspended solids (≥ 10 microns) from stormwater runoff, containing spills and minimising non-point source pollution entering downstream waterways.

The HumeCeptor® system is an underground, precast concrete stormwater treatment solution that utilises hydrodynamic and gravitational separation to efficiently remove total suspended solids and entrained hydrocarbons from runoff. First designed as an at-source solution for constrained, commercial and industrial sites it has been improved and expanded to service large catchments, inundated drainage systems, and capture large volume emergency spill events. The system is ideal for hardstands/wash bays, car parks, shopping centres, industrial/commercial warehouses, petrol stations, airports and major road infrastructure applications.

Independently tested, and installed in over 30,000 projects worldwide, the HumeCeptor® system provides effective, and reliable secondary treatment of stormwater for constrained sites. There are a significant number of benefits provided during installation, operation and ownership, including:

1. The system reliably removes a high level of TSS and hydrocarbons.
2. Each device is sized to achieve the necessary WQO on an annual basis.
3. Its performance has been independently verified.
4. High flows won't scour captured sediment.
5. Nutrients are captured along with the sediment.
6. Designs allow for emergency spill storage, directional change, multiple pipes and tidal inundation.
7. It is a fully trafficable solution.
