How to Identify the Quality of Membranes in Purified Water Equipment?

Dec. 17, 2020

As a China Pharmaceutical Equipment Supplier, let me share with you. Purified water equipment is mainly used in industries such as medical machinery, food, medicine, cosmetics, and health products. In recent years, with the continuous advancement of environmental protection concepts, major pharmaceutical factories and pharmaceutical companies have attached great importance to water quality, gradually expanded the application of purified water equipment, and have increasingly strict requirements on the filtration effect of purified water equipment.

How to Identify the Quality of Membranes in Purified Water Equipment?

Multiple-effect Water

The working principle of purified water equipment is to "purify" raw water into purified water. The raw water enters the purified water system to filter out impurities, colloids, odors and other insolubles in the water quality, and then enters the membrane of the purified water equipment after passing through various filter elements. The reverse osmosis membrane can remove all kinds of residues in the water, and only allow water molecules to pass through the membrane pores into the post-processing, and then process through the EDI technology to reach the ion water standard.

In purified water equipment, reverse osmosis membrane is the core component, which uses special separation membrane materials, which has the advantages of low investment cost, low energy consumption, good separation effect, and wide application. It can effectively remove colloids, microorganisms and dissolving in water. Impurities such as salt. The quality of the reverse osmosis membrane of the purified water equipment directly affects the filtering effect. Therefore, the choice of membrane in purified water equipment is very important.

The conductivity of pure water is an important indicator for evaluating the cleanliness of purified water equipment. Once it is found that the conductivity index is not within the standard, there must be a problem with the water quality. There are five main reasons for the unqualified conductivity of purified water. First, the pretreatment filter is not flushed regularly; second, the precision filter of the purified water equipment is contaminated and has not been cleaned and replaced in time; third, the reverse osmosis membrane is contaminated and has not been cleaned and replaced in time; fourth, the maintenance of the reverse osmosis system is lacking And maintenance; Fifth, the water temperature and the pH value of the inlet water are not within a reasonable range during water production, resulting in unqualified purified water conductivity.

In addition, in order to meet the water quality requirements of the biopharmaceutical industry, all purified water produced by purified water equipment needs to be monitored online in real time. Our company also has Multiple-effect Water still on sale, welcome to contact us.
