Daily Output 30-1000L, TDS≤30ppm, Salt Spray & Shock Resistant, Suitable for High-Salinity Seawater (35,000-42,000ppm)
Background: Core Water Pain Points for Coastal Living & Offshore Voyages
Coastal living and offshore voyages share common water challenges but also have unique needs, making traditional water supply methods inadequate:
Offshore Scenarios (Yachts/Fishing Boats/Sea Fishing)：
- Limited freshwater reserves; shortages occur after 3+ days of navigation, restricting bathing, cooking, and drinking;
- High cost of bottled water ($15-25/day for 3-5 people consuming 10L/day), occupying storage space, and plastic waste polluting the ocean;
- Harsh environments: Ship turbulence, salt spray corrosion, unstable power supply, making ordinary equipment prone to failure;
Coastal Scenarios (Vacation Homes/Fishing Villages/Remote Shores)：
- No municipal water supply; well water/surface water has high salinity (TDS 15,000-35,000ppm) and cannot be used directly;
- Large-scale desalination equipment is bulky, complex to install, and energy-intensive, unsuitable for households/small-scale use;
- Need to cope with high temperatures, heavy rains, humidity, requiring outdoor durability.
“Every time I go sea fishing for 3 days, I have to save freshwater—even face-washing water is used to wipe the boat,” said a senior angler. “For my coastal vacation home, I have to drive 20km to buy water. The well water is salty and astringent, making clothes stiff after washing. We urgently need a small, durable device that can make water directly from seawater.”
Core Challenges
- Processes high-salinity seawater (35,000-42,000 ppm), producing water that meets WHO drinking water standards (TDS ≤ 30 ppm, 99.99% bacterial/viral removal rate);
- Scenario adaptability: Portable models require lightweight design (≤15kg) and easy portability; marine models require resistance to vibration (≤20° tilt) and salt spray (IP67 protection);
- Low energy consumption: Portable models support multi-mode power supply (solar/battery/mains power), marine models are compatible with 12V/24V ship power, with average daily energy consumption ≤3kWh;
- Simple operation and maintenance: No professional skills required, starts in 5 minutes, filter element replacement cycle ≥6 months, low maintenance costs;
- Stability: Continuous operation without failure under extreme environments (-5℃-55℃ temperature, high humidity, salt spray corrosion).
Our Solution
Dual-Series Seawater Desalination Systems (Portable & Ship-Mounted)
To address the differences between the two scenarios, we have developed the ZH-P portable series (focused on mobility) and the ZH-S marine series (focused on stability), both utilizing the core technology of “pretreatment + low-pressure reverse osmosis + post-treatment mineralization,” achieving a one-step “seawater to freshwater” conversion without the need for additional purification:
