Description
An Anti scale liquid 20l (Antiscalant) is a pretreatment that gets injected into the feed water. Eventually that flows through the RO membrane, preventing the membrane from scaling. RO membrane scaling occurs when particles accumulate on a membrane, causing the membrane’s pores to plug.
Anti Scale Liquid 20l (Antiscalant) Industrial water treatment seeks to manage four main problem areas. Scaling, corrosion, microbiological activity and disposal of residual wastewater. Scaling occurs when the chemistry and temperature conditions are such that the dissolved mineral salts in the water are caused to precipitate and form solid deposits.
There are a large number of chemicals which can be used as antiscalants and dispersants to improve the operation of RO and nano filtration (NF) systems. Antiscalants are a family of chemicals designed to inhibit the formation and precipitation of crystallized mineral salts that form scale. Most antiscalants are proprietary organic man-made polymers (e.g., polyacrylic acids, carboxylic acids, polymaleic acids, organ ophosphates, poly phosphates, phosphonates, anionic polymers, etc.). The molecular weight of these polymers can range from 2000 to 10,000 Da.
Antiscalant technology for RO systems was initially derived from chemistries used in cooling water and boiler water applications. It should be duly noted that the large number of different anti scalant chemistries that have evolved. Have produced a wide variety of results and efficacy depending on the application and organic polymer used. However, they have to be used with caution.
