Modernizing wastewater treatment in Sri Lanka :: IWMI Blogs - International Water Management Institute (IWMI)

Photo: Hamish John Appleby / IWMI. According to the UN Joint Monitoring Program, less than three percent of the rural and about 12 percent of Sri Lanka¡¯s urban population is discharging its wastewater from toilets (¡®black water¡¯) into sewers. However, we shouldn¡¯t assume this wastewater ends up in sewage treatment plants (STP).

Acrylamide in Environmental Water: A Review on Sources, Exposure, and Public Health Risks | Exposure and Health - Springer

Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 ¡ãC for elongated time.

Polyacrylamide - Wikipedia

[1] Copolymers and modified polymers [ edit] Linear polyacrylamide is a water-soluble polymer. Other polar solvents include DMSO and various alcohols. Cross-linking can be introduced using N,N-methylenebisacrylamide. Some crosslinked materials are swellable but not soluble, i.e., they are hydrogels .

Biodegradation of Polyacrylamide and Its Derivatives | Environmental Processes - Springer

Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. Microorganisms have been shown

Water | Free Full-Text | Optimizing the Flocculation Effect of Cationic Polyacrylamide Prepared with UV-Initiated Polymerization by Response

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM. In this paper, the optimal flocculation conditions of a novel CPAM were
