A sand filter consists of several layers of graded sand. Wastewater is distributed evenly over the filter's surface. It then percolates through the sand, where it is treated by a biofilm within the system. The effluent from the system will be clarified to the required standard. Molloy Precast provide the following services:
A system designed to suit your needs
Systems can be housed in one of our precast tanks or in an in-situ built tank
Specially designed 4” distribution pipes
Sand filters can be used in conjunction with the Aswaflow wastewater treatment system
Delivery and/or installation of sand filters is available throughout the country.
