A gas-fired thermal power project in Zhejiang

The reverse osmosis (RO) system treats effluent from a wastewater treatment plant - pretreatment through ultrafiltration and reverse osmosis -to provide high-quality boiler make-up water for key process units.Since the project's launched in 2022, all three sets membrane systems across the workshops have been gradually upgraded with KeenSen BW-8040XLFR membrane model. Since the replacement and commissioning of membranes , the RO units have been operating with excellent stability.To date, both the permeate flow and water quality consistently meet the strict requirements of the end user, demonstrating the outstanding performance and reliability of KeenSen membrane.

A thermal power plant in Zhejiang

This power plant in Shaoxing uses river water as its source,which is treated through pretreatment, reverse osmosis (RO), and EDI to produce demineralized process water for industrial units.The system has a treatment capacity of 100,000 m³/day.
Since 2021, the plant has adopted membrane products from KeenSen, with nearly 5,000pcs membranes replaced to date. The RO systems have been operating stably, and the current permeate flow and water quality consistently meet the requirements of the owner's requirements.

A petrochemical company in Dalian

A petrochemical company in Dalian uses a reverse osmosis (RO) system to treat secondary effluent from a wastewater treatment plant,with a treatment capacity of 24,000 m3/day,providing make-up water for the boiler system.
In April 2024, the first pass membrane system in the workshop was fully upgraded with KeenSen BW-8040XLFR anti-fouling membranes. After installation and commissioning, the system has demonstrated stable performance, with both the permeate flow and water quality meeting the client’s operational requirements.

A Petroleum and Natural Gas Technology Company in Karamay

The project uses a reverse osmosis (RO) system to treat municipal tap water for boiler feed water, with a treatment capacity of 14,000 m³/day. In 2019,KeenSen BW-8040FR membrane were purchased and installed in the concentrate RO unit. Since commissioning, the system has been operating stably, with all performance indicators meeting production needs and technical specifications.

A Petroleum Company in Shaanxi Province

The project uses a reverse osmosis (RO) system to treat surface water (from the Yellow River) for use as boiler feed water and process water. In January 2019, KeenSen BW-8040FR membranes were used to replace imported brands. Since then, the system has been operating steadily, meeting the client's expected service life and performance requirements.
