Saline-Alkaline Water Purification Equipment Introduction
Saline-alkaline water purification equipment is specially developed for saline-alkaline water with salinity of 1500-55000mg/L and pH value above 8.5. Its core function is to remove excessive salt, alkaline substances and impurities through special processes, converting saline-alkaline water into clean water that meets the standards for irrigation, industrial and domestic use, while assisting in the improvement of saline-alkaline soil. The equipment is mainly divided into two categories: composite reverse osmosis type and electrodialysis dealkalization type. Core components include pretreatment dealkalization system, deep desalination unit, intelligent monitoring system and tailwater reuse device. It adapts to various saline-alkaline water sources such as surface and underground saline-alkaline water, with production capacity ranging from 0.5 to 500 tons per hour. Process parameters can be flexibly adjusted according to the degree of salinization and alkalization. With in-depth experience in saline-alkaline water treatment, Xi'an DIEN Water Treatment can customize exclusive saline-alkaline water purification equipment based on regional differences of salinization and alkalization, balancing purification effect and soil improvement demands.
Working Principle of Saline-Alkaline Water Purification Equipment
The core working principle of saline-alkaline water purification equipment is "dealkalization pretreatment + deep desalination", solving the dual problems of high salinity and high alkalinity, which is different from ordinary brackish water treatment processes. Firstly, the pretreatment dealkalization module (lime softening + activated carbon filtration) neutralizes alkaline substances, removes suspended solids and colloidal impurities, lowers the pH value of water, and prevents alkaline substances from corroding equipment and affecting desalination effect. Then it enters the deep desalination stage: composite reverse osmosis equipment intercepts salt and residual impurities through high-pressure membrane with desalination and dealkalization rate over 99%; electrodialysis dealkalization equipment realizes directional separation of salt and alkaline ions under electric field, completing desalination and alkalinity reduction simultaneously. The whole process is eco-friendly without using a large amount of chemical agents. Xi'an DIEN Water Treatment can optimize process combinations to improve purification efficiency and water quality stability, adapting to complex working conditions in saline-alkaline areas.
Advantages of Saline-Alkaline Water Purification Equipment
The core advantages of saline-alkaline water purification equipment fit the actual needs of saline-alkaline areas and highlight differentiated value. First, dual functions of desalination and dealkalization: it can simultaneously reduce water salinity and alkalinity, making effluent meet multi-scenario usage standards, and the tailwater can be used for saline-alkaline soil improvement. Second, strong working condition adaptability: it can cope with water sources with different salinization, alkalization and impurity content, suitable for all kinds of saline-alkaline areas such as Northwest and North China. Third, energy saving and consumption reduction: the water recovery rate can reach more than 75%, reducing water resource waste; later operation and maintenance are convenient without a professional maintenance team. Fourth, environmental protection and pollution-free: no harmful wastewater discharge, tailwater can be recycled, conforming to the concept of ecological management and sustainable development. Customized models from Xi'an DIEN Water Treatment can further optimize the tailwater utilization process and improve resource utilization efficiency.
Application Fields of Saline-Alkaline Water Purification Equipment
Saline-alkaline water purification equipment is mainly applied in saline-alkaline areas, covering agriculture, industry, civil life, ecology and other fields. In agricultural field, it is used for farmland irrigation; purified saline-alkaline water can effectively improve soil salinization and increase crop yield and quality. In industrial field, it serves factory production water and boiler make-up water, avoiding equipment scaling and damage caused by salt and alkaline substances. In civil field, it is applied to village drinking water purification to solve drinking water difficulties for residents in saline-alkaline areas. In ecological field, it is used for saline-alkaline land improvement and wetland water replenishment to improve regional ecological environment. It is also suitable for mine saline-alkaline wastewater treatment and water resource utilization of coastal saline-alkaline tidal flats. Xi'an DIEN Water Treatment can optimize equipment configuration according to the demands of different fields to precisely match usage standards.
Saline-Alkaline Water Purification Equipment Process Flow Chart
Process Flow of Saline-Alkaline Water Purification Equipment
Saline-alkaline water purification equipment follows a standardized process flow to realize dual empowerment of purification and ecological management: Raw water inlet (surface / underground saline-alkaline water) → Pretreatment (lime softening → quartz sand filtration → activated carbon filtration → precision filtration) → Desalination and dealkalization (composite reverse osmosis / electrodialysis) → Sterilization and disinfection → Clean water storage → Delivery to water points (irrigation / production / drinking). The treated tailwater is reused for saline-alkaline soil improvement. The whole process adopts automatic control, which can real-time monitor key parameters such as inlet water salinity-alkalinity and effluent water quality, and give timely alarms for abnormalities, ensuring stable equipment operation and balancing water resource utilization and ecological governance.
