Using membrane method to treat wastewater is also an important means of resource utilization. The main process includes conventional treatment in the front stage, such as flocculation and sedimentation, filtration, disinfection, etc., and membrane method in the back stage.
The ptfe repeatable nanomembrane will be used here.
Nanofiber filter media has high initial and operating efficiencies with very low pressure drop.
Take DuPont’s HMT nanofiber filter media sample with a weight of 10g/m2 as an example to compare with conventional filter media of the same type.
The former has a filtration efficiency of 99%, a flow rate of 300~350mL/(min·cm2), a scale holding capacity of 1.6g, and an initial pressure drop of 0.4psi; while the latter has a filtration efficiency of only 91%~92% and a flow rate of 100mL/ (min·cm2), scale holding capacity 1.1g, initial pressure drop 1.6~1.8psi.
The porosity of ptfe repeatable nanomembrane can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore diameter ranging from 0.1um to 0.5um, and has high and low temperature resistance ( -200℃-260℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
It can ensure complete retention of bacteria and other impurities while having a large flux.
PTFE film manufacturer specializes in the production of PTFE repeatable nano-membranes. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE films; the product materials produced They all use imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
