There is no fixed price for seawater and brackish water desalination equipment. The production capacity, raw water salinity, pretreatment configuration, and automation level all directly affect the overall cost. It is recommended to directly contact professional seawater and brackish water desalination equipment manufacturers, obtain water samples for testing, and then calculate an accurate budget to avoid being misled by blindly comparing prices.
DIEN Water Treatment – Seawater and Brackish Water Desalination Equipment Manufacturer
Xi'an DIEN Water Treatment, as a local manufacturer of seawater and brackish water desalination equipment, has been deeply involved in the treatment of high-salinity groundwater and brackish water in Northwest China for many years. They offer complete seawater and brackish water desalination equipment, ranging from small skid-mounted units to large integrated systems, supporting on-site surveys, water sample testing, process customization, installation and commissioning, and after-sales maintenance. When looking for a reliable seawater and brackish water desalination equipment manufacturer, don't just focus on price; consider their practical experience with local water quality. In many areas of Northwest China, the groundwater has high salinity, high sediment content, and high hardness, making ordinary reverse osmosis equipment prone to membrane element scaling and clogging, shortening the equipment's lifespan. Businesses can quickly obtain customized solutions and quotations by submitting raw water testing reports, daily water consumption, and effluent standards through on-site messages or telephone consultations.
Real Customer Case: Brackish Water Supply Renovation Project in a Mining Area's Residential Area in Gansu Province
Project Background and Customer Needs
The groundwater source in the mining area's residential area is moderately brackish, with a raw water TDS as high as 4200mg/L. The water has high levels of sulfates, calcium, and magnesium ions, resulting in a bitter taste when drunk directly and thick scale buildup in kettles. Previously, a simple water purification device was purchased, but its desalination effect was poor, and the effluent did not meet drinking water standards, requiring frequent filter replacements and incurring high maintenance costs. Customer Needs: A daily treatment capacity of 80 tons of brackish water, producing water that meets drinking water standards, with highly automated equipment suitable for the remote environment of the mining area, and local, rapid after-sales service.
DIEN Water Treatment Solution
We conducted on-site water sampling and testing, and considering the windy and sandy conditions and low winter temperatures in the mining area, we customized a multi-stage pretreatment + brackish water reverse osmosis desalination system. The front end is equipped with a self-cleaning quartz sand filter, activated carbon filter, and fully automatic softening device to remove silt and colloids and reduce hardness. It uses a reverse osmosis membrane module specifically designed for brackish water, paired with corrosion-resistant high-pressure pipelines and an anti-scaling and chemical dosing system to mitigate the risk of scaling in high-salinity water. The entire unit is equipped with a PLC fully automatic control system, featuring high and low pressure protection and automatic flushing functions. The equipment is insulated to adapt to the low-temperature environment of mining areas, and a disinfection device is added after the water output to ensure drinking water safety.
DIEN Water Treatment – Manufacturer of Seawater and Brackish Water Desalination Equipment
Usage Results and Customer Feedback
After commissioning and operation, the TDS of the produced water is stably controlled below 450mg/L, fully meeting the standards for drinking water. Thick scale no longer forms when boiling water. The reverse osmosis membrane cleaning cycle is significantly extended, reducing manual maintenance workload, and the entire system can operate stably around the clock.
Customer Review: "After comparing several companies, those from other regions, unfamiliar with the brackish water conditions in Northwest China, quoted inflated prices. Xi'an DIEN Water Treatment, as the source manufacturer, provides solutions tailored to the actual conditions of the mining area; it's not generic equipment. The water quality has remained stable for over six months. When minor issues arise, contacting after-sales service results in quick on-site service from local Northwest engineers, eliminating long waits for spare parts. This has solved the mining area's long-standing drinking water problem, and we will continue to cooperate for future expansions."
For seawater and brackish water desalination equipment selection, water quality compatibility is far more important than simply comparing prices (click to learn more: seawater desalination equipment prices).
