The word polymer simply means “many parts,” which covers a broad range of compounds including styrofoam and DNA. Polymers are long-chain molecules with repeating parts. For wastewater treatment, polymer pertains to polyelectrolytes, which are polymers with molecular chains that produce an electric charge when dissolved.Cationic polymers produce a positive charge while anionic polymers produce a negative charge. These long chain molecules attract particles of an opposite charge while offering many sites for attachment. In some cases, both positively and negatively charged polymers are used in a scheme called dual polymer flocculation, where the polymers are introduced in sequence. There are
Hello, Polymer, It’s Nice to Meet You
Polymer can be expensive, unpleasant to work with, and as slippery as wet ice, but what it does is nothing short of amazing.
