Description
technical field [0001] The invention belongs to the field of microfiltration membrane pilot test machines, and in particular relates to an integrated fully automatic microfiltration membrane pilot test machine. Background technique [0002] Microfiltration membrane generally refers to a filtration membrane with a pore size between 0.1-1um, which mainly mechanically intercepts suspended solids and macromolecular colloidal substances. At present, most of the microfiltration membranes on the market are made of PVDF material, and are made in the form of tubular microfiltration membranes. The feed water flows through the membrane filaments at high speed to form cross-flow filtration. This type of microfiltration membrane module has high operating pressure and high energy consumption. Moreover, the membrane filaments made of PVDF are generally hydrophilic and cannot withstand long-term immersion in high-concentration acid and alkali, and the service life of the membrane is relati...
