Description

High-permeability water treatment membrane

Technical Field

The invention relates to the technical field of high-permeability water treatment membranes, in particular to a high-permeability water treatment membrane.

Background

Nanofiltration membrane separation is a method for separating, classifying, purifying and enriching double-component or multi-component mixed gas or liquid by using the difference of selective permeability of membranes on each component in a mixture and taking external energy or chemical potential difference as a driving force. The membrane process, in which the pore diameter of the membrane is on the nanometer scale and is suitable for separating dissolved components with the molecular weight of 100-1000 and the molecular size of about 1nm, is called nanofiltration.

The transmembrane pressure difference required by membrane separation is generally 0.5-2.0 MPa, which is 0.5-3 MPa lower than the pressure difference required by a reverse osmosis membrane to achieve the same osmotic energy. Depending on the operating pressure and separation limits, NF can be qualitatively interposed between reverse osmosis and ultrafiltration, sometimes also referred to as low pressure reverse osmosis or loose reverse osmosis. The study of the NS-300 membrane in j.e.cadotte was the beginning of the study of NF membranes in the 70 th century. At the time, israel desalination company expressed the membrane separation process between reverse osmosis and ultrafiltration by "mixed filtration", and later companies in the united states called nanofiltration for this membrane technology, which has been used to date. Thereafter, NF developed rapidly and membrane modules were commercialized in the mid-80 s. NF has become one of the hot spots of research in the field of membrane separation in the world.

When the water treatment membrane filters water, the higher the efficiency of water permeating the membrane is, the better the efficiency is, and the water permeation efficiency can be improved.
