  • PVA in wastewater treatment facilities
    Feb 10, 2020
    Polyvinyl alcohol (PVA) is a water-soluble polymer commonly used in wastewater treatment facilities for various applications. Here are some ways PVA is utilized in these facilities:   Flocculation: PVA can act as a coagulant or flocculant in wastewater treatment processes. It helps to bind together suspended particles, colloids, and other impurities, forming larger flocs that can be easily removed from the water.   Sludge conditioning: PVA is used as a sludge conditioner to improve the dewatering properties of sludge. When added to the sludge, it enhances the formation of stronger flocs, which aids in the separation of water from the sludge during dewatering processes such as centrifugation or filtration.   Filtration aid: PVA can be added to filtration systems as an aid to improve the filtration efficiency. It can help in the removal of fine suspended solids, improve the clarity of the treated water, and prevent clogging of filter media.   Foam control: In wastewater treatment facilities, excessive foam can hinder the proper operation of processes such as aeration tanks and clarifiers. PVA is used as an antifoaming agent to reduce foam formation and stabilize the foam that may already be present.   Membrane applications: PVA is also employed in membrane-based processes such as reverse osmosis and ultrafiltration. It can be used as a membrane modifier to enhance the membrane's performance, selectivity, and resistance to fouling.   It's important to note that the specific application and dosage of PVA in wastewater treatment vary depending on the treatment process, water quality, and desired outcomes. Proper understanding and consideration of the system requirements are necessary to ensure effective and sustainable use of PVA in wastewater treatment facilities.   Website: Whatsapp: (+)86 13851435272 E-mail: ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
