Self-cleaning FRP filters introduced for salty water

A range of self-cleaning filters in fibre-reinforced plastic (FRP) designed for brackish, brine and seawater applications such as desalination has been introduced by Forsta Filters in the USA.

All wetted components of the FRP series are constructed from seawater-resistant plastic and other high alloy materials, which, Forsta claims, makes the series the only one of its kind. The filters can withstand pressures up to 150 psi (10.3 bar) and feature all the same benefits of Forsta Filters’ stainless steel self-cleaning water filters.

The filters are available with an on-line or in-line flange configuration to accommodate simple installation, and easily integrate with any pipeline. Flow rates are in the range 15-20,000 GPM (950-1,260 L/s)

A two-stage screening process distinguishes the FRP series. A coarse screen is responsible for straining out large debris from the water source, and the fine screen purifies water to the designated micron rating (5-4,000µm).

As with all Forsta self-cleaning filters, the FRP filter’s short backwash cycle never interrupts the main system flow.
