Pretreat Plus® Y2K

RO and NF Antiscalant

Pretreat Plus® Y2K is formulated for large membrane systems. This product is a broad spectrum antiscalant like Pretreat Plus®-0100 but has greater scaling control capacity. Thus it provides greater reliability for systems containing hundreds of elements and uses lower doses allowing smaller antiscalant tankage and associated equipment. It protects membranes from inorganic foulants even when these are present in high concentrations. Pretreat Plus® Y2K 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® Y2K has also lowered capital costs of reverse osmosis (RO), and nanofiltration (NF) systems by increasing membrane lifetime. Due to the success of Pretreat Plus® Y2K, it continues to displace older water treatment technologies and competitors products.
