Power Plant Water Treatment Reverse Osmosis System: Stable Boiler Feed Water Solution

Power Plant Water Treatment Reverse Osmosis System: Stable Boiler Feed Water Solution

Power plant water treatment reverse osmosis system is a heavy-duty water purification system specially designed for thermal power and cogeneration stations. It can adopt the anti-corrosion frame of Carbon steel epoxy-coated RO equipment, and realize long-distance data monitoring by matching RO equipment remote monitoring system. Designed for continuous 24-hour heavy-load operation, this system effectively removes dissolved salts and scaling ions to supply qualified feed water for power station boilers.

Product Description

Power plant water treatment reverse osmosis system belongs to large-scale heavy-duty water treatment equipment, serving as the core pretreatment link of power plant boiler feed water preparation. Power station boilers have extremely strict requirements on water salinity and hardness. If raw water containing lots of calcium, magnesium ions and silicate directly enters boilers, serious scaling, pipeline corrosion and heat efficiency attenuation will occur, even bringing hidden dangers of pipe burst under high pressure.

According to the site environment of power plants, customers can select stainless steel or adopt anti-corrosion treatment to build Carbon steel epoxy-coated RO equipment, adapting to humid and salt-spray workshop atmosphere. Reserved industrial communication interfaces support seamless connection with complete RO equipment remote monitoring system, enabling operation engineers to remotely view pressure, flow and water quality data, receive real-time fault alarms. Different from general industrial RO equipment, this power plant dedicated system strengthens anti-scaling, anti-pollution and continuous operation performance. The whole system includes multi-media pre-treatment, activated carbon filter, security filter, reverse osmosis main unit and automatic chemical dosing unit, providing stable low-salinity water for thermal power, biomass power and cogeneration units all year round.

Working Principle

Power plant water treatment reverse osmosis system runs based on multi-stage pretreatment plus parallel multi-membrane rack pressure-driven separation technology. Raw water firstly enters graded pretreatment sections to filter suspended sediment, organic pollutants and absorb residual chlorine, preventing irreversible oxidation and blockage of RO membrane elements. After precision security filtration, qualified feed water is distributed to each independent membrane rack and pressurized by high-efficiency high-pressure pumps.

Under stable industrial operating pressure, water molecules penetrate semi-permeable reverse osmosis membranes. Dissolved salts, scaling ions, colloids and silicate are intercepted and discharged outwards in concentrated water. The purified low-hardness water flows into intermediate water tanks as the pre-treated feed water for power plant boilers. The automatic dosing system continuously adds anti-scaling agents according to real-time water quality changes. The main PLC platform executes staggered cyclic flushing for each membrane rack. Optimized process layout allows the whole system to keep recovery rate ≥75% under long-term 24-hour continuous heavy-load operation.

Technical Features
