Reverse Osmosis (RO) is a water treatment technology that separates dissolved contaminants from water by using specially-designed membranes. RO membranes are semi-permeable which only allow “pure” water to permeate through them while removing the vast majority of dissolved solids from the feedwater stream. RO applications can include drinking water production, power generation, steam boiler pretreatment, wastewater treatment, and the manufacturing of beverage, semiconductor, and pharmaceutical products.
