With 13 Years of Expertise, Delivering High-Quality Water Purification Solutions for Marine and Land Applications

Deyuan Marine recommends its full series of reverse osmosis seawater desalination equipment, covering small, medium, and large-scale products. With core advantages such as a salt rejection rate exceeding 99.2% and an ultra-long service life of 15-20 years, we provide stable and reliable drinking water solutions for scenarios including ocean shipping, island construction, drilling platforms, and brackish water regions, redefining industry quality standards.

Thirteen Years of Dedication, Forging Technological Excellence

We focus on innovation and breakthroughs in marine and land-based reverse osmosis technology. Through in-depth collaboration with leading global component suppliers such as Dow, Hydranautics, and Germany's Speck, our core components utilize premium imported materials, ensuring equipment stability and durability from the source.

Our Reverse Osmosis Water Makers Series Equipment has obtained multiple authoritative certifications, including CCS and ISO9001, and holds several national patents. Our products are constructed with SUS316 stainless steel, offering exceptional rust-proof and corrosion-resistant properties. They operate stably within a broad temperature range of 5-45°C and under operating pressures of 3.5-5.5MPa, compatible with power specifications from 220V/50HZ to 480V/60HZ to meet the installation and usage requirements of diverse scenarios.

Comprehensive Product Portfolio Covering Diverse Water Purification Needs

Deyuan Marine has established a full-range product system with capacities from 0.5 to 2000 tons per day, precisely meeting the water demand scale of diverse users: 

Small-scale Seawater Desalination Equipment (0.5-10 TPD): Compact and easy to install, these units feature self-protection designs and manual multi-port valves. Ideal for mobile or low-water-volume scenarios such as ocean-going fishing vessels, yachts, and small islands, the equipment has a net weight of only 15-800kg, ensuring simple, efficient operation and maintenance.

Medium-scale Seawater Desalination Equipment (20-60 TPD): This range includes standard models and specific custom solutions. With a system recovery rate of up to 35% and product water TDS as low as 20 PPM, these systems are suitable for drilling platforms, fishery processing vessels, and medium-sized islands. They support manual or automatic sand filter backwashing for more convenient operation and maintenance.

Large-scale Seawater Desalination Equipment (100-2000 TPD): Employing a containerized modular design, these systems can achieve a production capacity of up to 2000 TPD. Designed for large-scale needs such as major island complexes, municipal water supply, and industrial water use, the equipment integrates a touch-screen HMI for real-time visualization of operational status and faults, enabling convenient and efficient control.

All product output water strictly complies with China's "Standards for Drinking Water Quality" (GB5749-2006). Equipped with high-pressure pump over-pressure protection, under-pressure protection, audio-visual alarms, and RO membrane cleaning systems, the equipment ensures comprehensive safety and stable operation, delivering complete peace of mind for users.

One-stop Service System for Shared Value and Success

Our professional technical team provides tailored solutions for clients, offering one-on-one follow-up service throughout the entire process—from initial consultation and system design to installation, commissioning, ongoing maintenance, and parts supply—guaranteeing efficient equipment operation.

Thanks to reliable product performance and superior after-sales service, this product series has been widely deployed in major domestic and international projects, including CNOOC drilling platforms, island water supply projects in Mauritania (Africa), and ocean-going tuna vessels. It has earned high recognition from clients across shipping, energy, municipal, and other sectors. Moving forward, the company will continue to enhance product performance, offering more innovative and cost-effective solutions to address global water scarcity challenges.
