Staging - Reverse Osmosis

Advanced Reverse Osmosis Technology

Staging - “Reject Staging” refers to a technique where the reject from one group of RO pressure vessels becomes the feed stream of a second group of RO pressure vessels. Reject staging is used to increase the recovery of water. A one stage system typically could recover 50 - 60% of the feed water stream with 2 and 3 stage systems operating at 75 - 80% and greater than 85% respectively.

“Product Staging” referred to as “multiple pass”, is a technique where the product of the first group of RO pressure vessels becomes the feed water stream for a second stage. Product staging is used to increase the quality of the product water.
