New Seawater Filtration System

 

Declining water supplies and increasing demand has resulted in an increase in the use of desalination equipment. The higher chloride levels found in brackish or seawater are likely to damage 316L stainless steel, so where filtration is required the filter vessel needs to be manufactured from expensive alloys or lined vessels need to be used.

To help reduce the costs of constructing desalination plants Amazon Filters Ltd has developed a new system for the filtration and brackish and seawater. It consists of a 20”, 40” or 60” length 27 Series GRP (Glass Reinforced Plastic) housing and a large diameter, high surface area SupaPleat FFC cartridge.

The 27 Series GRP housing consists of a GRP polymeric body with super duplex stainless steel end fittings. The housings are designed so flow through the cartridge is optimised in ‘out to in’ mode which keeps the design as simple as possible. The inlet and outlet connections are set perpendicular to each other (side inlet, in-line outlet) to help ensure quick and easy cartridge change-out without the need to remove process pipework.

The robust construction provides a maximum operating pressure of 10 bar and maximum operating temperature of 45º C. To provide protection against UV light damage the external surface is painted and coated.
