Dosing Recommendations

PreTreat Plus 0100 Anti-Scalant should be injected into the feedstream prior to the static mixer. Effective pH range is 5 — 10. If frozen, may be thawed and mixed before use. Stability is excellent, but best used within 12 months.


Antiscalant is shipped as a concentrated solution.  This concentrated solution must be mixed with clean RO water to the proper level for each system specifically.  A water analysis and RO system flow rates must be used to figure the site specific mixture and dose rate.  Please call 1-805-777-7037 or send your water analysis and flow rate info to to give you the right  dosage and mixture.  Over or Under concentrated solutions could damage your RO membranes.
