While most RO chemical pretreatments need to be injected from separate tanks, these products may be blended in a single RO pretreatment tank and injected into the feedwater. The line invests into chemical inter-compatibility as essential in RO operations.
Compatibility of pretreatment chemicals is easily tested by mixing small quantities of the chemicals in a test-tube. If they're compatible, they will not change in appearance. If they are not compatible, a change in appearance will be evident.
