Tricel Sandcel - Sand Polishing Filter
Sandcel as a sand polishing filter provides a dual function of polishing the effluent from a wastewater treatment system and disposing of the treated liquid into groundwater. It incorporates an enclosed sand filter, which can be installed under or overground at varying heights to suit all site conditions. Sandcel filters can also be designed for larger applications by our inhouse team.
Sandcel sand polishing filters are designed to the EPA Code of Practice as tertiary treatment systems. These filters are the perfect solution for the treatment and disposal of effluent from a secondary treatment unit. The filters comprise of stratified layers of certified sands according to the EPA Code of Practice.
They are enclosed in GRP impermeable panels which will not rot or decay, ensuring the structure of the filter will hold for many years.
The filters can be installed above or below ground with all pipework accessible from a service pod.
Sandcel filters provide excellent polishing of treated effluent. Sample testing of some sites where a Sandcel and Tricel Novo wastewater treatment plant were in operation have shown final effluent quality of <1 mg/ltr BOD₅.

Many layers of pea gravel and sand are used inside. The sand filter can be installed above or below ground.
