Overview

 

The Wattech WRO-8H Series Industrial Reverse Osmosis Systems are engineered to economically produce high purity water by removal of dissolved minerals, bacteria, particles, and organic impurities. Each WRO machine is constructed using the highest quality components and materials for

 

reliable operation and exceptional performance. Our standard machines are available with product water outputs from5,600-68,000 LPH (112,000-1,360,000 LPD).

 

Wattech also offers a wide variety of machine options, pre/post treatment equipment, distribution pumps, and integrated controls for a complete water treatment system. Our specialty is skid mounted, pre-piped, and pre-wired equipment allowing for quick installation and start-up time. Other types of membrane technology are also available including two-pass, two-train, cellulose acetate (CA), and nanofiltration (NF) for custom applications. Wattech engineers are ready to work with you to design a system meeting your water treatment requirements.
