Description
Pretreat Plus® Gypsum Concentrate
Antiscalant/Dispersant/Antifoulant
Antiscalant & antifoulants work differently but all with the same goal, keeping your RO/NF membranes running at maximum productivity. Antifoulants work to prevent organic and biological material, colloids, silt, and other fine particulates from attaching themselves to the membrane. Antiscalant temporarily keeps sparingly soluble salts in solution so they do not stick to the membrane and form scale. There are many different types of scale and foulants which can hinder membrane performance. Depending on your water chemistry, you may need a broad spectrum antiscalant, a specifically targeted antifoulant or a product which provides protection for both.
Pretreat Plus® Gypsum Conc. is a targeted performance antiscalant that is specifically formulated for feedwaters with the highest levels of calcium sulfate. It is effective over a wide range of concentrations and does not flocculate dissolved polymers such as residual coagulants or iron- or aluminum-rich silica. A special utility is in its application as a substitute for pretreatment with ion exchange beds. Use of this product is recommended for reducing the operating and capital costs of reverse osmosis (RO) and nanofiltration (NF) systems.
Features
- Specifically formulated to control high concentrations of calcium and other sulfates.
- Controls sulfate scale over a large concentration range.
- Strong dispersing capabilities.
- Compatible with RO, NF, and UF membranes from all major manufacturers.
- Liquid formulation is convenient and easy to use.
- Certified under NSF/ANSI Standard 60 for drinking water production.
- Can be mixed with all Pretreat Plus® and Protec® RO products to boost control of fouling.
Applications
Targeted: Targeted line of antiscalant & antifoulants meant for particularly difficult and unique applications.
