Example of an Ashco RFSIII-T finished product.

Ashco's single cell recirculating sand filter for residential use.  This system should be used with other types of treatment as a means of additional treatment.  The treated Home Aeration Unit effluent flows by gravity to the recirculation tank bottom zone.  The recirculation pump in the bottom zone pumps the effluent via a spray grid onto a sand filter.  The effluent trickles down the filtrate media where it is treated by naturally occurring micro-organisms populating the sand filter. After passing through the biological filter media, the treated effluent is stored in the bottom zone where it is mixed with incoming septic tank effluent.  The mixing of septic tank effluent with biologically filtered effluent creates a dilute waste to be recirculated through the sand filter.  The treated effluent is discharged either by gravity or a small discharge pump to disinfection and/or discharge.
