Sand Polishing Filters

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.

How a Tricel Sandcel Sand Polishing Filter works

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.

Treatment efficiency:

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.

What is included with a Sandcel?

Whenever an existing wastewater treatment plant doesn’t perform at its best anymore or needs an upgrade, the Sandcel is always a great complementary solution. The sand polishing filter offers many advantages including an efficient disposing of the treated effluents into groundwater.

Before the launching of the project, it has to begin with a full site inspection and assessment monitored by the local authorities. Our product will then be designed based on your needs and requirements. It is made out of GRP panels following the EPA code of Practice.

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

Frequently asked questions


Why is maintenance important?

Once your wastewater treatment system is installed, the work is not totally done yet!

You or your landlord are responsible for maintaining your system for several reasons. For example, not de-sludging a septic tank led to a sludge accumulation and may cause a malfunction of your system.

In Ireland, there are approximately 500,000 wastewater treatment systems and most of them are septic tanks. Lack of tank desludging and maintenance of wastewater treatment system is an issue as this poses risks to health or environment.
