Solids Interceptor Oil Separator – SIOS

Solids Interceptor, Oil Separator, Enviroconcepts


Enviro Concepts is a leading manufacturer of cost-effective, packaged, modular solids interceptor and oil-water separator system for wash bay and industrial effluents. The SIOS (Solids Interceptor Oil Separator) systems are designed for efficient removal of suspended solids, oil and grease and are offered as part of our Water Treatment Discharge package.


These skid-mounted systems are pre-engineered, pre-assembled and factory tested minimising site installation and start-up time. The SIOS range collects wastewater from a wash pad gutter or inground sump and puts it into the solids interceptor tank to settle most of the suspended solids. The clarified wastewater then gravity flows to the oil-water separator to remove oils and grease. Treated water is then discharged as trade waste (sewer) and the settled solids are drained back to the gutter for easy collection and disposal.
