The 180 Fiberglass Reinforced Plastic (FRP) Series filters offer an ideal solution for corrosion resistance in brackish, brine and seawater filtration applications. All wetted components of the FRP Series self-cleaning filters are constructed from seawater- resistant plastic or other high alloy materials.
A3-180FRP with 25 micron screen for sea water filtration
Forsta Filters was asked to provide a solution for RO pre-filtration for sea water with high chloride content and high water temperature.
With the FRP filter line, Forsta’s applications engineers were able to specify a quick solution that would hold up very well in these harsh environments, where other filters have failed.
The customer’s idea was to install a self-cleaning water filter to replace the expensive and labor intensive cartridge filters. Forsta automatic backwash filter model A3-180FRP filter is flowing 80-100gpm through 25 micron screen. The filter uses less than 5 gallons of water per 12 second backwash, without disrupting the main flow. This solution saves the customer from spending time and money continuously replacing cartridges.
Filter Characteristics:
- Flow Rate: 15 – 4,500 gpm
- Flush cycle duration: 6 – 20 seconds
- Flush valve size: single 1″ or a single 2″
- Screen opening: 5µ – 4000µ
- Temperature: 150ºF
- Flush Volume: 4 – 50 gallons per backwash
- Working pressure: 35 – 150 psi
