How does antiscalant work for a - Water Treatment Guide
How does antiscalant work for a reverse osmosis water treatment application? An antiscalant is a pretreatment injected into the feedwater before the feedwater enters the RO membranes. Its presence delays the reaction between calcium magnesium and bicarbonate. This results is scale not forming as the water is being purified by the RO.
Rajindar Singh, in Hybrid Membrane Systems for Water Purification, 2005. Antiscalant threshold treatment. Scale inhibitors or antiscalants (A/S) are generally organic compounds containing sulphonate, phosphonate, or carboxylic acid functional groups and chelating agents such as carbon, alum, and zeolites that sequester and neutralise a particular ion which may be formed.

Scaling and antiscalants - Lenntech
Scaling means the deposition of particles on a membrane, causing it to plug. Without some means of scale inhibition, reverse osmosis (RO) membranes and flow passages within membrane elements will scale due to precipitation of sparingly soluble gas, such as calcium carbonate, calcium sulfate, barium sulfate and strontium sulfate. Most natural waters contain relatively high concentrations of

Cooking Anionic Polyacrylamide in Petroleum Additives (PAM) - Cooking Anionic Flocculant, Polyacrylamide
Anionic Polyacrylamide in Petroleum Additives (PAM) is a linear polymer comprised of monomers unit with functional groups of amide that adsorb on to the surface of particles. These particles are bridged together by the long polymer chain drawing
Product Application . Anionic PAM: It is widely used in waste water treatment of chemical industry, municipal sewage treatment, such as coal washing, mineral processing, metallurgy, iron and steel industry and electronic industry.It is also used in oil industry to enhance oil recovery which is widely used. In addition, it can be used as paper additives and textile pulp agent.
