    Preparing 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

    Industrial wastewater treatment

    Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment.. Most industries produce some wastewater.Recent trends have been to minimize such production or

  • polyelectrolyte

    Polyelectrolyte

    Polyelectrolytes are polymers whose repeating units bear an electrolyte group. Polycations and polyanions are polyelectrolytes. These groups dissociate in aqueous solutions (water), making the polymers charged.Polyelectrolyte properties are thus similar to both electrolytes and polymers (high molecular weight compounds) and are sometimes called polysalts.
