Shandong Ecolink Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of water desalination equipment in China, featured by quality products and good service. If you're going to wholesale high quality water desalination equipment, welcome to get more information from our factory.
Product Introduction
Seawater desalination equipment can convert seawater and brackish water with salinity ≤40000 ppm into freshwater that meets drinking water standards (GB 5749).
It solves the fundamental contradiction faced by coastal areas, islands, offshore vessels, and water-scarce industrial zones where "surrounded by ocean yet lacking usable water."
Compared with traditional distillation methods, our reverse osmosis seawater desalination system reduces energy consumption by more than 60%, and the water production cost is only 1/3 of distillation.
Turn seawater into sellable freshwater, solving water shortage problems in one step.
Product Overview
This series of seawater desalination equipment adopts reverse osmosis (RO) technology as the core, using pressure difference as the driving force, allowing water molecules in seawater to pass through the membrane while salts, bacteria, and viruses are retained.

|
Multi-media + precision filtration pretreatment |
Influent SDI ＜3, protecting membrane elements |
Membrane cleaning cycle extended to 6–12 months |
|
316L stainless steel pipelines and high-pressure parts |
Resistant to seawater corrosion, design life ≥15 years |
No leakage risk, fewer after-sales issues |
|
Containerized modular design |
Factory prefabrication, only water and power connection required on-site |
Installation and commissioning ≤2 days, ready to use immediately |
|
PLC automatic control + online instruments |
Real-time monitoring of conductivity, pressure, flow |
Unattended operation, remote monitoring supported |
Because equipped with an energy recovery device, the pressure of high-pressure brine is recovered and transferred to the influent, reducing overall system energy consumption by 40%. For every 1000 tons of water produced, about 300 kWh of electricity is saved compared with peers, saving tens of thousands of RMB annually.

Product Process / Technical Strength
Process flow diagram:
Seawater intake → chemical dosing (coagulant/antiscalant) → multi-media filter → security filter (5 μm) → high-pressure pump → RO membrane modules → product water (post-mineralization/disinfection optional) → freshwater tank
