Brief Introduction
The ULP 4040 ro membrane is suitable for treating wastewater with a TDS range of 1000 to 2000.
High water yield and high desalination rate even under low pressure, with a desalination rate of nearly 99.5%.
Partial removal of TOC, SiO2
Reduces system costs by approx. 20%

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
