Brief Introduction
This series of membrane elements features low operating pressure, small investment in equipment, good and stable desalination performance. With a maximum desalination rate of 99.85%, seawater of different salinities can be desalinated into fresh water for direct consumption. In addition to the very high desalination rate, the feed water temperature range is also extended, reducing the cost of system operation.

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
