Pretreat Plus® – Silica is similar to Pretreat Plus® – 0100 with additional silica scaling inhibition. This product can be used in any size system where the feed water has 25+ ppm of silica. Pretreat Plus® – Silica is a broad spectrum antiscalant controlling calcium carbonate, silica, iron, and all slightly soluble salts that would form scale in its absence. It protects membranes from inorganic foulants even when these are present in high concentrations. Pretreat Plus® – Silica does not react with other treatment chemicals such as coagulants. This product has greatly reduced operating costs by eliminating the need to inject acid, and extending the period between membrane cleanings. Because of its effectiveness, Pretreat Plus® – Silica has also lowered capital costs of reverse osmosis (RO), and nanofiltration (NF) systems by increasing membrane lifetime. Due to the success of Pretreat Plus® – Silica, it continues to displace older water treatment technologies and competitors products.
