What does an antiscalant do?

Antiscalants have been shown to be effective in extending the intervals between chemical cleanings of the RO membranes. These products are generally formulated to include inorganic phosphates, organophosphonates, and dispersants. Use Antiscalant products that have been approved by the membrane manufacturer, and follow all direction in applying and controlling the product dosage. Some Antiscalant contain negatively charged polymers and dispersants that can react with cationic polymers that might be dosed up stream prior to the media filters. The Antiscalant must be compatible with these polymers; otherwise, the reaction product will foul the membranes.
