FRP Collectors

Product Overview

Seawater desalination plants using Reverse Osmosis (RO) typically use large diameter metal pipes to feed and collect concentrate to and from the FRP membrane pressure vessels. As seawater is highly corrosive, these pipes are typically made of expensive materials like super stainless steel or super duplex materials. Protec Arisawa has developed an innovative system using fiber reinforced plastic (FRP) to economically replace the expensive high grade metal piping.
