Description

Tank type ultrafiltration equipment

Technical Field

The invention relates to the technical field of solid-liquid separation, in particular to tank type ultrafiltration equipment.

Background

Ultrafiltration is a membrane separation technology capable of purifying and separating a solution, and an ultrafiltration membrane is a solution separation device which takes ultrafiltration membrane wires as filter media and takes pressure difference at two sides of the membrane as driving force; the ultrafiltration membrane only allows the solvent, inorganic salt and micromolecular organic matters in the solution to permeate, and intercepts the suspended matters, colloid, protein, microorganisms and other macromolecular matters in the solution, thereby achieving the purposes of purification and separation;

ultrafiltration membranes are used in water treatment engineering in large quantities, and ultrafiltration technology plays an increasingly important role in the fields of reverse osmosis pretreatment, drinking water treatment and the like;

However, when water is filtered in the prior art, only a single filtering mode is often adopted to filter liquid, so that the filtering efficiency is low and the filtering effect is poor.

There is thus an urgent need to redesign a new tank ultrafiltration device to solve the above problems.
