Scaling can be defined as the deposition of particles on a membrane that leads to the plugging of the membrane. RO membranes and the flow passages within the membrane elements are susceptible to the formation of scales due to the precipitation of sparingly soluble salts, such as strontium sulfate, barium sulfate, calcium carbonate, and calcium sulfate. Generally scaling occurs on RO membranes when the saturation limit is crossed by the concentration of the scale-forming substances thereby producing added solids within the RO feed water. These substances are hard to remove owing to their low nature of solubility. Scaling alleviates the efficacy of the membranes in removing the solids concentration and leads to more frequent cleanings.
RO antiscalants or antifoulants manifests as special chemical formulations that when administered to the membrane system tend to enhance the solubility of sparingly soluble salts such as BaSO4, CaSO4, SrSO4, CaCO3, and CaF which are the most common scales of concern. In order to run the reverse osmosis system efficiently and in a well organized manner, these antiscalants are to be used as an essential component in the operation of the system.
Hypersperse MDC220 and Hypersperse MDC150 serves as Antiscalants to be used in Reverse Osmosis Systems. They both serve as highly effective liquid antiscalants that has been specially formulated for the controlling of scale precipitates and to help in the reduction of particulate fouling within membrane separation systems.
Using Hypersperse MDC220 and Hypersperse MDC150 as potent antiscalants account for longer run times and extended element life resulting in reduced operating and capital costs. For maximum efficacy, these products should be administered prior to the static mixer or cartridge filter housing. Years of use of these products in industrial applications show incomparable results in membrane separation processes including reverse osmosis (RO), ultrafiltration (UF) and nanofiltration (NF) applications.
Various types of Antiscalants for Reverse Osmosis Systems can be found in the ChemEqual directory which is the largest online directory for chemicals supplier all over the world wherein buyers can have a direct access to all the products and their equivalent brands along with having the convenience of sending direct enquiry to suppliers.
