A coal chemical enterprise in Anhui

The water source of the reclaimed water reuse system in a coal chemical industrial park in Huaibei, Anhui Province, is a mixture of power plant circulating wastewater and industrial wastewater. The industrial wastewater mainly consists of production and domestic sewage from enterprises in the Huaibei new coal chemical synthetic materials base park. After biological treatment by a newly built wastewater treatment plant, the wastewater meets the Class A standard of the "Discharge Standard for Pollutants from Urban Wastewater Treatment Plants". The overall treatment scale of the reclaimed water reuse system is 20000 m3/d, with a total of 4 reverse osmosis membrane systems. Three of them use KeenSen BW-8040FR membrane elements, while one uses imported  Fouling-Resistant membrane elements for comparison. There is no significant difference in the operation indicators of the membrane systems, which has been well received by the owner.

A coal chemical enterprise in Hulunbuir

The Hulunbuir Coal Chemical Project, with a processing capacity of 30,000 m³/d, began using KeenSen membrane products in 2018. Product models include BW-8040FR, BW-8040XLFR, and SW-8040MR, used in workshop desalted water systems, reclaimed water systems, concentrated brine systems, and zero-discharge high-pressure reverse osmosis systems, respectively. The excellent performance of KeenSen reverse osmosis membrane elements has reduced the frequency of chemical cleaning, saving operating costs, and the good price-performance ratio has received customer praise.

Desalination water project of a certain steel mill in Sichuan

The desalination project uses river water as its source, with a total treatment capacity of 15000 m³/d. In April 2023, the membrane elements of the two reverse osmosis systems in this project were replaced with KeenSen BW-8040FR Fouling-Resistant membrane elements. Since commissioning, the system has been operating stably, and both water production and Rejection Rate meet project requirements.
