Polishing Filters
Polishing filters exist in the percolation area of a bioCycle™’s wastewater treatment systems and provide an effective way of eliminating any grease and suspended solids that have not been removed by the septic tank itself.They work by allowing wastewater to flow into a distribution box that then channels into a number of pipes.

The liquid is transmitted into a gravel underlay which distributes to the soil for further physical, chemical and biological treatment.The design of all bioCycle™ polishing filters is covered by professional indemnity insurance, with each being constructed to specifically for the site. They can also been installed to work with a geothermal heating system.
