The power industry is the cornerstone of modern economic and social development.As the source of electricity generation, power plants consume and discharge large volumes of water, requiring comprehensive water treatment systems covering both boiler make-up water production and water reuse applications.
SHUIYI Membrane Technology provides a complete membrane-based water treatment solution for power plants, enabling efficient water conservation, recycling and sustainable utilization throughout the plant.
1 、SHUIYI HR Series RO Membrane Address the Challenges of Boiler Make-up Water Treatment
Boiler make-up water is both water-intensive and energy-intensive, and it is also the most strictly regulated water-use segment in power plant water quality control. Impurities in water can readily damage boiler equipment, so the feedwater must be pretreated to meet the required standards.
Selecting the appropriate boiler water treatment process requires careful consideration of both water source characteristics and required water quality standards. Moreover, the boiler make-up water systems have very low fault tolerance; any malfunction may lead to a shutdown of the entire steam-water cycle. Proper operation and maintenance, optimized chemical dosing and periodic chemical cleaning can not only ensure system stability, but also improve water recovery and reduce energy consumption.
SHUIYI HR Series Reverse Osmosis Membrane
The SHUIYI HR Series RO Membrane is a product developed by SHUIYI Membrane Technology, based on improvements to brackish water reverse osmosis processes. This product offers high salt rejection and high permeate productivity, with the following notable advantages:
High Salt Rejection
- Stable performance with an average rejection rate of 99.7%.
- Excellent resistance to chemical cleaning and short-term chlorine exposure due to its highly crosslinked separation layer.
High Permeate Productivity
- Available in a larger 440 ft2membrane element, providing stable permeate flow of up to 44 m3/d.
- Capable of maintaining reliable water production under low-temperature operating conditions.
2 、SHUIYI HRFR Series RO Membrane + TIPS Series Pressurized UF Membrane: Solving the Challenges of Reclaimed Water Reuse in Power Plants
The reclaimed water in power plant comes from diverse sources with intermittent discharge, leading to significant fluctuations in water quality. It mainly includes circulating blowdown water, chemical concentrated water and treated domestic wastewater. The volume of reclaimed water discharge is considerable and its recovery value is high. Efficient treatment directly improves the overall water utilization efficiency of the plant.
This type of water typically contains elevated levels of suspended solids, hardness and COD. It requires processes such as coagulation, sedimentation, filtration, softening and desalination to meet purification standards before it can be reused. The treatment process must be customized based on the characteristics of the water source.
SHUIYI HRFR Series Reverse Osomosis Membrane
- Salt rejection rate: 99.65%
