using “polyelectrolyte” polymers in water treatmentPreparing PolyaminesPreparing Acrylamide CopolymersIn-Line DilutionThese are low gramme-molecular weight cationic polymers. They are all sold as slightly viscous to viscous (50 to 10,000 centipoises) solutions. These products can be pumped direct out of a drum or container without any preliminary preparation. This is an undeniable benefit, especially since these products are very stable.However, good secondary dilution must absolutely be undertaken at the feeding pump delivery point (1在suezwaterhandbook上查看更多信息

Organic polyelectrolytes in water treatment ScienceDirect
All polymers used as flocculants in water treatment, must be water soluble. In aqueous solution polymers very often adopt a random coil configuration, shown schematically in Fig. 1.For very high MW polymers, the size of the coil is typically of the order of a hundred nm, with the size being proportional to the square root of the MW.

They are used in water treatment and for oil recovery. Many soaps, shampoos, and cosmetics incorporate polyelectrolytes. Furthermore, they are added to many foods and to concrete mixtures (superplasticizer). Some of the polyelectrolytes that appear on food labels are pectin, carrageenan, alginates, and carboxymethyl cellulose. All but the last

It be dissolved in water at about a 10% solution and fed to the boiler or the feed water line. WT 25 L Is a liquid alkali builder for boiler water treatment. It can be pumped directly into de-aerator storage or the feed water line. It can also be fed with phosphate or sulphite. WT 100 Is an alkali builder for boiler water treatment.
Water Chemistry American Chemical Society
Water is one of the most versatile of all chemicals. It comprises about 75% of the Earth’s surface and is an integral part of every ecosystem—we drink it, play in it, and use it in a wide variety of manufacturing processes. Water chemists study the impact of water on other elements in these
