Behavior of organic polymers in drinking water purification

Polymers and product contaminants can react with other chemicals added to the water treatment process to form undesirable secondary products. Owing to concern over human health, Japan and Switzerland have adopted regulations prohibiting the use of synthetic organic polymers in drinking water treatment.

Sometimes organic polymers, known as coagulant aids, are used to assist with coagulation. These polymers may contain residual acrylamide or epichlorohydrin monomers. Monitoring for these chemicals in drinking-water is not normally appropriate, because measurement in water is very difficult. Instead, these chemicals are managed by specifying a

Reducing Polymers In Wastewater Treatment, Wastewater

Reducing polymer usage saves wastewater treatment plants precious time, money and labor. The use of polymer products is needed in wastewater treatment when the traditional iron-based (“ferric”) and aluminum-based compounds are used to deal with the core problem of phosphorus reduction.

Facile synthesis of Melamine-Modified porous organic polymer

In this study, a novel porous organic polymer modified by melamine (MA-POP) was prepared via a post-modification procedure for the Hg 2+ removal from aqueous solutions. The use of melamine as the rigid crosslinker endowed the polymer with high surface area (669 m 2 g −1), total pore volume (0.668 mL g −1) and nitrogen content.

Coagulation can also be affected by the addition of water-soluble organic polymers with numerous ionized sites for particle charge neutralization. Flocculation can be enhanced by the addition of high-molecular-weight, water-soluble organic polymers. These polymers can increase floc size by charged site binding and by molecular bridging.
