Scale control extends the membrane life: The Kemira KemGuard product range includes polymeric antiscalants and specialized multifunctional formulations designed to inhibit mineral scale precipitation (e.g. calcium carbonate, calcium sulfate, calcium phosphate, barium sulfate, silica and silicate) and disperse suspended / colloidal impurities encountered in brackish sea and water application re-use. Proper scale control ensures a cleaner system and ultimately increases the longevity of both membranes and the equipment. Our KemGuard® products are fully compatible with both the membranes and the chemicals used in water pretreatment. All our products intended for potable water treatment are certified by NSF and meet UNE, or similar local regulations.
