The control of water pH and alkalinity levels is very important in RO Treated water in order to reduce corrosion. Depending on the natural feed water alkalinity it is often necessary to add an alkalinity builder in order to establish the correct water chemistry by raising the water pH which helps to protect the system from acid corrosion. Our NSF Certified WTP200 - FOOD GRADE RO WATER PH BOOSTER helps in effectively restoring Ph level of RO treated water.
