PVP K30 (Tech-grade) Applied for Sewage Disposal Industry

Name: Polyvinylpyrrolidone (PVP K30)
Abbreviation: Povidone K30
CAS Number: 9003-39-8; Molecular formula: (C6H9NO)n
Appearance (Colour): White or off-white
Usage: Pore-Former 
Application of polyvinylpyrrolidone PVP K30 in water treatment membranes: Polyvinylpyrrolidone in the water treatment industry is not only a modified film material material but also an excellent pore-making agent, so it has been very good application in the water treatment industry. With the progress and development of society, membrane separation technology has become one of the most concerned water treatment technologies in sewage reuse engineering due to its effluent quality and applicability.

PVP as a pore-making agent, the membrane produced has many properties. Due to its chemical stability, it can effectively control the size of membrane aperture and the distribution of pores and it can increase the density of membrane pore and improve the permeability of membrane; Improve the membrane surface hydrophilicity, good biocompatibility. Environmental protection wastewater treatment industry: membrane separation wastewater treatment and water treatment process has become the mainstream process of this industry, among which PVDF membrane for nanofiltration or ultrafiltration is an important part of the membrane industry.

At present, the consumption of its product PVP 30 has reached 3000 tons per year. With the increasing scarcity of water resources in the world, the economic value of water recycling has become increasingly prominent with the strengthening of environmental governance in major countries, the demand of PVP K30 in the field of environmental water treatment will increase in the future. In the next 3-5 years, the usage of PVP K30 in the industry of environmental water treatment will reach or exceed 10,000 tons. The odds are very high. Relevant experimental data showed that the larger the PVP mass fraction, the higher the membrane filament flux, the more surface faces, and the better the performance, so the demand for PYP in PVDF membrane is expected to continue to increase.
