Reverse Osmosis Systems


A Comprehensive Wastewater Treatment Offering for Industrial, Metalworking, and Surface Treatment Industries

Reverse Osmosis System - Prab.com

PRAB designs Industrial Reverse Osmosis Systems (RO Systems) ranging in capacity from 1 GPM (1440 GPD) to 200 GPM (288,000 GPD) which remove up to 99.5% of dissolved salts and virtually all colloidal and suspended matter from the most challenging waste and feed water applications. Typically for industrial, metalworking, and surface treatment applications we use our RO technology as a final process after Ultrafiltration or chemical treatment of waste and feed water.

Our Reverse Osmosis Systems are engineered specifically for your water treatment needs by an experienced team of application engineers. PRAB RO systems are built using only industrial-grade components and proven membrane technology that will provide reliable, long-term operation. The PRAB Reverse Osmosis system will arrive at your site fully tested and ready to clean contaminates from water. PRAB also provides the pretreatment equipment and chemistry required to ensure optimal performance and life span of your RO membranes.

What is Reverse Osmosis?

Reverse Osmosis / RO is a technology used to remove dissolved solids and impurities from water using a semi-permeable RO membrane which allows the passage of water but leaves the majority of dissolved solids and other contaminants behind. The RO membranes require water to be under high pressure, greater than osmotic pressure, to do this. The water that passes through the RO membrane is referred to as the permeate and the dissolved salts that are rejected by the RO membrane is referred to as the concentrate. A properly designed and run RO system can remove up to 99.5% of incoming dissolved salts and impurities.

PRAB offers a complete line of pilot equipment to validate system operation and performance prior to purchase. Available pilot units are; Tramp Oil Removal equipment, Centrifuges, Ultrafiltration, Vacuum Distillation, and Reverse Osmosis. Pilot units are meant to act as a sample test to provide confidence the recommended equipment will meet the output requirements of your application. Flow rates range from 2 GPM (2,880 GPD) up to 10 GPM (14,400 GPD).
