Electroplating Reverse Osmosis Equipment Introduction
Electroplating reverse osmosis equipment is an efficient water treatment and wastewater recovery device specially designed for the electroplating industry. It is mainly used for pure water preparation and wastewater treatment & reuse in electroplating production. Composed of pretreatment system, reverse osmosis main unit, concentrated water recovery unit and intelligent control system, it can flexibly adapt to different electroplating processes such as chromium plating, zinc plating and nickel plating. Balancing the demands of production water purity and wastewater emission reduction, it serves as the core equipment for green and compliant production in the electroplating industry.
Working Principle of Electroplating Reverse Osmosis Equipment
Its working principle is based on the selective interception characteristics of reverse osmosis membranes. Pressure is applied by a high-pressure pump to force water molecules in raw water or wastewater to pass through the reverse osmosis membrane, while intercepting heavy metal ions, electroplating additives, organic matter and other impurities in the electroplating liquid, realizing efficient separation of water and pollutants. For pure water preparation, it removes impurities from raw water to produce qualified pure water. For wastewater reuse, it recycles water resources and useful components in wastewater, reducing wastewater discharge and resource waste, with a desalination rate and impurity interception rate of over 98%.
Advantages of Electroplating Reverse Osmosis Equipment
The equipment features remarkable core advantages: First, high separation efficiency, which can accurately intercept heavy metal ions and various additives to guarantee electroplating water quality and wastewater recovery quality. Second, energy saving and consumption reduction, with a water recovery rate of 60%-80%, greatly cutting fresh water consumption and wastewater treatment costs. Third, stable operation with fully automatic control, easy operation, continuous running and low maintenance cost. Fourth, eco-friendly and environmentally compliant, it reduces electroplating wastewater discharge and recycles valuable components, helping enterprises achieve clean production.
Application Fields of Electroplating Reverse Osmosis Equipment
It covers the whole industrial chain of electroplating: widely applied in various electroplating workshops including hardware electroplating, electronic electroplating and auto parts electroplating. It can not only produce high-purity pure water for electroplating pretreatment and plating solution preparation, but also treat electroplating rinsing wastewater to realize water resource recycling. It is also used for concentration and recovery of electroplating waste liquid to improve resource utilization efficiency.

Process Flow of Electroplating Reverse Osmosis Equipment
The process flow is concise and efficient, divided into five steps: First, pretreatment, adopting multi-media filtration, precision filtration and activated carbon adsorption to remove suspended particles, organic matter and residual chlorine in raw water or wastewater and protect the reverse osmosis membrane. Second, high-pressure pressurization, the pretreated water is pressurized to the rated pressure by a high-pressure pump. Third, reverse osmosis separation, water molecules pass through the membrane to form product water (pure water or reused water), while impurities are discharged or recycled along with concentrated water. Fourth, advanced treatment, EDI treatment or disinfection is adopted as required to ensure effluent meets standards. Fifth, storage and transportation, qualified water is stored in water tanks and delivered to each terminal of electroplating production or recovery unit through pipe network with stable and controllable whole process.
