Removal of metal ions by polyelectrolyte ultrafiltration. Wastewater treatment

1994
Journal Articles

Abstract

Ultrafiltration based on the use of co-polyelectrolytes bearing carboxyl, sulfonate, and tertiary amino groups was used to investigate removal of divalent ions from aq. solns. The efficiency of metal sepn. was evaluated for model solns. of Cu2+, Zn2+, Mn2+, and CrO42-, and exceeded 99.9% in the runs involving co-polyelectrolytes with carboxyl groups. Industrial wastewater was treated by the suggested technique; its applicability in environmental protection was also demonstrated. [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.

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.

Agricultural wastewater treatment

Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations like milk and egg production. It may be performed in plants using mechanized treatment units similar to those used for industrial wastewater.
