Coastal Factory Seawater Desalination Equipment Introduction
Customized by Xi'an DIEN Water Treatment for coastal factories, this seawater desalination equipment is a large-scale industrial complete set of desalination facilities. Its water production capacity ranges from tens to hundreds of tons per day, which can be flexibly customized according to the factory’s process water demand. Adopting modular and standardized design, the equipment supports later capacity expansion and upgrading. Core components are made of corrosion-resistant and high-strength materials, adapting to the complex operating environment of coastal factories and the high-salinity, highly corrosive characteristics of seawater. Meanwhile, equipped with an intelligent monitoring system, it realizes automatic production control and real-time water quality monitoring, ensuring stable equipment operation and meeting the continuous water demand for factory production.
Working Principle of Coastal Factory Seawater Desalination Equipment
Coastal factory seawater desalination equipment adopts the combined process of "Pretreatment + Reverse Osmosis + Advanced Treatment" to meet the strict water quality requirements of industrial production. Working principle: Firstly, seawater is extracted from coastal waters through the water intake system. The pretreatment system (quartz sand filtration, activated carbon filtration, cartridge filtration, ultrafiltration) removes large particles, suspended solids, organic matter, colloids and other impurities in seawater, preventing blockage of core desalination components and protecting normal equipment operation. Then the pretreated seawater is pressurized by high-pressure pumps and delivered to the reverse osmosis membrane module. By the sieving effect of semipermeable membranes, harmful substances such as salt, heavy metals and microorganisms in seawater are intercepted to separate pure fresh water. Finally, the fresh water is further purified by the advanced treatment system (ion exchange, EDI) to ensure the effluent meets factory production water standards such as boiler water and process water, satisfying water demands of various industrial sectors.
Advantages of Coastal Factory Seawater Desalination Equipment
Tailored for industrial production needs, Xi'an DIEN Water Treatment’s coastal factory seawater desalination equipment has five core advantages. First, large water production capacity: it meets the large-scale water demand of coastal factories with a water recovery rate over 70%, effectively improving seawater utilization. Second, stable water quality: the advanced treatment process guarantees qualified effluent, suitable for production water requirements of chemical, power, electronic, textile and other industries. Third, energy saving and consumption reduction: equipped with energy-saving high-pressure pumps and heat exchange systems with optimized processes, it reduces energy consumption by 25%-35% compared with traditional equipment, greatly cutting long-term factory water costs. Fourth, stable operation: modular design facilitates maintenance and inspection; core components feature long service life and low failure rate, ensuring uninterrupted factory continuous production. Fifth, environmental compliance: no harmful emissions during operation; concentrated brine can be reused after secondary treatment for seawater aquaculture, road cleaning and other purposes, complying with national environmental protection policies.
Application Fields of Coastal Factory Seawater Desalination Equipment
This equipment is mainly applied to various industrial enterprises in coastal areas, including chemical plants, power plants, electronic factories, textile mills, pharmaceutical factories, food processing plants, seawater aquaculture processing plants and more. Whether it is power plants requiring large amounts of cooling water or electronic factories with strict water quality standards, Xi'an DIEN Water Treatment can provide matched seawater desalination solutions to supply stable and high-quality fresh water for factory production. At present, the equipment has served many coastal industrial enterprises, effectively solving water shortage problems, reducing water costs and gaining high recognition from clients.

Process Flow of Coastal Factory Seawater Desalination Equipment
Xi'an DIEN Water Treatment’s coastal factory seawater desalination equipment features a scientific and reasonable process flow suitable for large-scale industrial production. Specific steps: 1. Seawater Intake: Seawater is extracted from coastal waters through dedicated pipelines with intercepting devices to filter large floating debris. 2. Pretreatment: Sequential treatment by quartz sand filtration (removing suspended solids), activated carbon filtration (removing odor and organic matter), cartridge filtration (removing fine impurities) and ultrafiltration (removing colloids and microorganisms) to make seawater meet desalination standards. 3. High-pressure Pressurization: Pretreated seawater is pressurized by high-pressure pumps to the operating pressure of reverse osmosis membranes. 4. Reverse Osmosis Desalination: Seawater passes through reverse osmosis membrane modules to separate fresh water and concentrated brine; concentrated brine is recycled or discharged in compliance with regulations after treatment. 5. Advanced Treatment: Fresh water enters ion exchange or EDI system to remove residual trace salt and impurities for qualified water quality. 6. Storage and Conveyance: Qualified fresh water is stored in industrial water tanks and delivered to each production link via pipelines to meet factory water demand.
