Product Details

Professional water treatment factory

1. China Factory Quality, Global Competitive Pricing

As a professional seawater desalination equipment manufacturer in China, we leverage mature production technology, standardized workflows, and bulk component procurement to offer prices 30–50% lower than international brands—without compromising quality. Our 10TPD and 20TPD models are mass-produced, high-export products with stable performance and proven reliability in global projects.

2. Premium Core Components for Long-Term Reliability

  • High-Efficiency RO Membranes: Equipped with top-grade seawater reverse osmosis (SWRO) membranes (desalination rate ≥99%), effectively removing salts, bacteria, viruses, and impurities to produce safe drinking water meeting WHO/GB standards.
  • Marine-Grade Stainless Steel Pumps: Corrosion-resistant high-pressure pumps ensure stable operation in high-salinity seawater, extending service life and reducing maintenance costs.
  • Automatic Control System: PLC-based intelligent control enables 24/7 unmanned operation, with real-time monitoring of water quality, pressure, and flow—easy to operate and maintain.

3. Perfect for Island Nations & Remote Coastal Areas

  • Compact & Space-Saving: Skid-mounted or containerized design (20GP/40HQ) saves land space, easy to transport and install—plug-and-play within 24 hours after arrival.
  • High Adaptability: Operates stably in high salinity (≤40,000ppm), wide temperature range (0–45°C), and harsh coastal climates.
  • Cost-Effective Operation: Energy recovery system reduces power consumption by 30–40%, lowering long-term operational costs for island communities.

4. Flexible Customization & Fast Delivery

  • Custom Solutions: Tailor system capacity, configuration, and accessories to meet specific client needs (e.g., solar integration, remote monitoring, special material requirements).
  • Short Lead Time: Standard 10TPD/20TPD models are in stock or with fast production cycles—delivery within 2–4 weeks for global orders, much faster than international competitors.
  • Full-Service Support: From design and manufacturing to installation, training, and after-sales service, we provide one-stop solutions for clients worldwide.

Centered on professional seawater reverse osmosis technology, our desalination systems adopt high-interception SWRO membranes as the core filter material. The multi-stage filtration system thoroughly tackles high-salinity seawater, efficiently intercepting sodium ions, chloride ions and various heavy metal substances. Meanwhile, it filters out algae, suspended solids, bacteria, viruses and other harmful pollutants. The equipment maintains a stable desalination rate above 99%, processing raw seawater with 20,000–40,000ppm TDS into purified freshwater below 500ppm TDS. The processed water fully conforms to WHO and international  water standards, completely satisfying daily drinking, cooking and long-term domestic water needs for residents and staff.

10TPD desalination plant, 20TPD RO desalination system-One stop complete product

  • Strong Environmental Adaptability: Designed exclusively for harsh coastal and island environments. The skid-mounted structure resists humidity and salt corrosion, working steadily within a salinity range of 20,000–40,000ppm, ideal for all island regions.
  • Easy Installation & Customization: Compact all-in-one skid design requires minimal space and supports plug-and-play installation. We offer full customization on working voltage, containerized packaging, automatic control and remote monitoring to fit different project scenarios.

Wide Application Scenarios

  • Island Countries & Remote Islands: The most mainstream application scenario. Suitable for permanent island residents, isolated villages, and community collective water supply, solving the long-term freshwater shortage of remote islands with insufficient natural freshwater resources.
  • Marine Tourism & Resorts: Perfect for coastal hotels, private island villas, beach resorts and camping bases. Stable freshwater supply meets tourists’ daily drinking, bathing and catering water demands, improving service quality.
  • Offshore Working Facilities: Adapt to offshore oil & gas platforms, wind power stations, marine research stations and docks. Replace expensive water transportation, supply daily domestic water for on-site working staff and reduce operational expenditure.
  • Marine Vessels & Aquaculture: Applicable for large fishing boats, cargo ships, yachts and offshore fish/shrimp farms. Provide drinking water for crews and high-quality fresh water required for aquaculture breeding to increase survival rate of aquatic products.
  • Coastal Industrial & Military Sites: Serve coastal construction camps, mining bases and frontier outposts. The equipment runs stably in harsh environments to continuously provide reliable domestic and partial production water for on-site teams.

  • Cost & Delivery Advantage: As direct factory supplies, our desalination units beat famous international brands in pricing. Mass production greatly shortens lead time; standard 10TPD and 20TPD models can be delivered rapidly to help clients cut procurement and operation costs.
  • Strong Environmental Adaptability: Designed exclusively for harsh coastal and island environments. The skid-mounted structure resists humidity and salt corrosion, working steadily within a salinity range of 20,000–40,000ppm, ideal for all island regions.
  • Easy Installation & Customization: Compact all-in-one skid design requires minimal space and supports plug-and-play installation. We offer full customization on working voltage, containerized packaging, automatic control and remote monitoring to fit different project scenarios.

Why Choose Chinese Desalination Manufacturers

  • Mature Industrial Supply Chain: China owns the world’s complete water treatment industrial chain. All core accessories including SWRO membranes, high-pressure pumps and filter housings are sourced locally. This realizes one-stop production, avoids accessory matching issues, and greatly lowers after-sales replacement costs compared with overseas brands.
  • High Cost-Performance Ratio: Compared with European, American and Japanese brands, Chinese factory products feature the same filtration performance and service life. Without brand premium, clients can save 30%-50% of procurement budget, which is the top priority for small and medium-sized water supply projects.
  • Powerful Customization Capability: Different from international brands with fixed standardized configurations, we support flexible personalized upgrades. Clients can adjust voltage, add intelligent auto-flush system, remote monitoring function and solar power matching solution to adapt to various special regional environments.
  • Fast Global Delivery & Stable Inventory: Relying on large-scale batch production advantages, standard 10TPD and 20TPD desalination units are always in stock. We support diversified shipping methods and shorten overall lead time, solving the long delivery cycle pain point of imported customized equipment.
