No matter what the origin: lake, pond, river, stream, etc., intake water will be contaminated with a variety of suspended solids. In order to prevent fouling of equipment and ensure optimal efficiency, it is desirable to remove these suspended solids.

An excellent solution to this problem is the Orival automatic self-cleaning screen filter. Installed as a full flow filtration system on the intake, it can protect the equipment by removing the majority of suspended solids. Due to the nature of most surface water and the high flow rates typically required, it may be necessary to install a bank of Orival filters to provide sufficient screen area.

Orival filters are used to control zebra mussels and quagga mussels by stopping shells, adults, veligers, larvae and eggs from passing beyond the point of filtration. This protects piping, valves and other equipment from becoming clogged and impaired.
