Microfiltration pores, easy to attach microorganisms, enhance aerobic biochemical process
The average pore size of the enhanced polyvinylidene fluoride curtain membrane produced by Jinlong is less than 0.03 μm, which can effectively attach bacteria and microorganisms with a pore size distribution in the range of 0.02 - 0.03 μm. The turbidity of the produced water is less than 0.3 NTU, ensuring excellent water quality.
The excellent interface supports compounding and super-hydrophilicity
The Jinlong enhanced polyvinylidene fluoride curtain film has excellent interfacial support and composite properties, with a smooth, dense, and superhydrophilic outer surface. When water droplets contact the surface of the enhanced polyvinylidene fluoride curtain film, the water contact angle can reach 0 ° within 3 seconds.
