Csm Membrane Manufacturers Price

High desalination rate at high flow rates;Resistant to chemical or biochemical effects;
Less affected by pH, temperature and other factors;High mechanical strength and service life.

Functioning at low operating pressures;

Fully automatic membrane winding technology. Fully automated winding technology is the only way to produce highly consistent elements with a precise membrane area. Fully automatic technology does not require sacrificing inlet channel thickness to produce the highest membrane area elements.

How to prevent the growth of micro-organisms in packaging?

When the protective fluid appears cloudy, it is most likely due to microbial growth. Membrane elements protected with sodium bisulphite should be checked every three months. 

When the protective fluid becomes cloudy, the element should be removed from the storage seal, re-soaked in fresh protective fluid at a concentration of 1% (by weight) food grade sodium bisulphite (not cobalt activated) for approximately 1 hour and re-sealed and sealed, and the element should be drained before repackaging.
