In industrial production processes such as chemical engineering, electroplating, mining, and food processing, large quantities of wastewater with high salinity are generated. This wastewater has a complex composition of salts and ions, making it extremely difficult to treat. Ordinary water purification equipment cannot achieve effective desalination. Direct discharge not only wastes water resources but also incurs environmental penalties. For applications involving large-flow, high-salinity wastewater (50 tons), the requirements for equipment stability, desalination precision, and shock resistance are particularly high. Xi'an DIEN Water Treatment has specifically developed a 50-ton RO reverse osmosis system for high-salinity wastewater desalination, to meet the needs of large-volume, high-salinity industrial wastewater purification and reuse.
Traditional, simple water purification devices can only filter out sediment and impurities. They are essentially incapable of handling extremely high salt concentrations or highly difficult-to-filter dissolved ions. In such cases, membrane elements are prone to rapid fouling, system pressure spikes dramatically, and desalination rates plummet, among other problems. The DIEN brand's 50-ton RO reverse osmosis system is specifically customized for high-salinity wastewater conditions. Unlike ordinary pure water equipment, it features membrane modules that withstand high pressure and resist fouling, along with a high-pressure water supply system with variable frequency capability. It can withstand the osmotic pressure generated by high-salinity water, achieving a stable and efficient desalination effect with a salt rejection rate exceeding 99%. It is perfectly suited for industrial applications involving the concentration, desalination, and reuse of high-salinity wastewater.
Addressing the industry-wide problems of scaling and membrane clogging associated with high-salinity wastewater, this RO system is equipped with a complete enhanced pretreatment system, forming a closed-loop treatment process. It utilizes multi-media filtration, including activated carbon adsorption and precision security filtration, to remove suspended solids, organic matter, and colloidal impurities from the wastewater. Simultaneously, a scale inhibitor dosing system effectively inhibits salt crystallization and scaling, protecting the reverse osmosis membrane elements from the source. The entire system can operate continuously for 24 hours a day, stably treating 50 tons of high-salinity wastewater every hour. The treated effluent exhibits uniform and stable quality and can be directly reused in production processes, thus significantly reducing the company's water costs.
The DIEN 50-ton RO reverse osmosis system is a large-tonnage industrial-grade device. It features a modular integrated design, compact structure, small footprint, and easy installation, and can be adapted to existing factory sites for upgrades. Equipped with a fully automatic intelligent control system, it supports automatic flushing, adaptive pressure adjustment, and automatic fault alarms, requiring no dedicated personnel and significantly reducing manual maintenance costs. With a thickened, corrosion-resistant body and brand-name core components, it is suitable for high-intensity, high-load industrial wastewater treatment conditions, boasting a low failure rate and long service life.
This 50-ton high-salinity desalination equipment rejects generic layouts and is adapted to different high-salinity wastewater treatment scenarios. By avoiding a universal design, it balances treatment efficiency with energy conservation and cost reduction. This equipment comes from Xi'an-based manufacturer, DIEN Water Treatment, which specializes in custom manufacturing of large-tonnage industrial water treatment equipment. They can optimize equipment process configuration based on the enterprise's wastewater salinity, treatment regulations, and reuse needs. Furthermore, the manufacturer provides free water quality surveys, customized solutions, on-site installation, and lifetime maintenance – a one-stop service – to help enterprises efficiently handle high-salinity wastewater treatment problems, achieve wastewater discharge standards and water resource recycling, and assist enterprises in compliant cost reduction and green production.
