Abstract

Suspended solids are removed from wastewaters and waters contg. 10-4-10 g solids/L using poly(di-Me diallyl ammonium chloride) and a water-sol., highly branched, high mol. copolymer of di-Me dially ammonium chloride and 0.1-3.0 mol% of a crosslinking comonomer, e.g., Me triallyl ammonium chloride, tetraallyl ammonium chloride, triallyl amine hydrochloride, N,N,N',N'-tetraallyl ethylenediamine hydrochloride, or methylene bisacrylamide. The flocculant is used at an amt. of 0.05-2%, based on the solids, and at 278-340 K. The method effectively removes iron hydroxide sol 10-4 g/L from water. [on SciFinder (R)]

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. Some industrial facilities generate wastewater that can be treated in sewage treatment plants.

Sewage

Sewage (or domestic sewage, domestic wastewater, municipal wastewater) is a type of wastewater that is produced by a community of people. It is typically transported through a sewer system. Sewage consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality. Sub-types of sewage are greywater (from sinks, bathtubs, showers, dishwashers, and clothes washers) and blackwater (the water used to flush toilets, combined with the human waste that it flushes away).

Wastewater treatment

Wastewater treatment is a process which removes and eliminates contaminants from wastewater and converts this into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation). The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant.
