Feed water can be from different sources and contain different contaminants such as suspended solids and dissolved salts. Pretreatment focuses mainly on the removal of suspended solids while in Reverse Osmosis systems, water concentrations can cause salt to precipite out due to supersaturation.

Dow’s ACUMER™ antiscalants can be used to reduce this precipitation causing the system to work at a higher recovery rate. Adding just a small concentration of ACUMER increases the recovery due to improved solubility of sparingly soluble salts and keeps the RO membranes cleaner and free of deposits. This in turn reduces water use and maintenance time and extends membrane life. Our expert teams will also work with you to choose just the right solution for your RO needs.
