Recirculating Filtration System

The Recirculating Filtration System consists of three parts – Pumping Station, Media Filter, and Distribution Box.  In the recirculating filtration system, the wastewater passes through the Media Filter to the Distribution Box.  One-fifth of the wastewater goes on to the greenhouse for further treatment and four-fifths returns to the Pumping Station to be pumped to the Media Filter again.  The number of times the water passes through the filter is called the recirculation ratio and is determined by the desired quality of treatment.  This recirculation ratio is 4:1
