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.

On June 6, 2025, the 17th Watertech China successfully wrapped up its three-day event at the National Exhibition and Convention Center (Hongqiao) in Shanghai. As one of the world’s leading trade shows for the water treatment industry, it brought together cutting-edge technologies and innovative prod
1. Water Quality in CanadaIn Canada's Shield area, water is relatively soft because hard rocks do not release much calcium into the water. However, in regions with more limestone than granite, large amounts of calcium dissolve into the water, making it hard. The water hardness in these areas usually
The 2025 WQA Convention & Exposition was held from April 22 to 24 at the Long Beach Convention Center in California, USA. The exhibition area covered more than 25,000 square meters. As an authoritative annual event in the North American water treatment industry, it attracted over 400 exhibitors and
