T.Jian Household Seawater Desalination Machine: 2T/Day Dual-Membrane System, Ceramic Ultrafiltration & RO Desalination Plant for Coastal & Island Home
- Advanced Dual-Membrane Tech: Combines Ceramic Ultrafiltration and Reverse Osmosis (RO). The durable ceramic filter highly removes sediment and microbes, preventing bio-fouling.
- High Desalination Rate: Features a salt rejection rate of ≥98.5%, deeply removing salinity to produce fresh, sweet, and safe direct-drinking water.
- Heavy-Duty & Compact: Integrated in a robust cabinet with corrosion-resistant components, delivering a reliable and independent water supply for coastal homes.
Description
For households on islands and in coastal regions, issues such as freshwater scarcity, saline water quality, and unstable supply have long been persistent challenges. How can one reliably and safely produce ready-to-use freshwater from seawater? Tianjian Water Treatment offers the most reliable solution. Zhejiang Tianxingjian Water Treatment has dedicated years to ceramic membrane water treatment technology, steadfastly addressing water resource challenges through technological innovation. Its household seawater desalination unit—capable of producing two tons of freshwater daily—utilizes a dual-membrane process combining ceramic ultrafiltration and reverse osmosis. The ceramic membranes, characterized by their high-temperature, corrosion, and fouling resistance, efficiently filter out sediment, colloids, and microorganisms; meanwhile, the reverse osmosis stage ensures deep desalination—achieving a salt rejection rate of ≥98.5%—to produce clean, sweet-tasting water that meets safety standards and is suitable for direct consumption. By leveraging cutting-edge technology to transform seawater into pure, high-quality water for daily use, the company ensures that every coastal household enjoys a stable, safe, and independent freshwater supply.

Q1: What are the main advantages of Cuiyuan Ceramic Membranes over traditional organic membranes?
A: Our Ceramic Ultrafiltration Membranes offer several superior benefits:
- Unmatched Durability: Service life exceeds 20 years, significantly longer than the 3-5 years of organic membranes.
- Higher Precision: A constant 30nm pore size ensures the removal of bacteria, viruses, and even microplastics.
- Superior Flux: Our membranes deliver fluxes 3 to 10 times higher than organic alternatives.
- Robustness: Capable of withstanding operating pressures up to 0.7 MPa and temperatures up to 800°C.
- Chemical Stability: Resistant to high concentrations of chlorine and various chemicals (pH 2-14) for intensive cleaning.
Q2: Is the water treated by your systems safe for direct drinking?
A: Yes. Our 30-nanometer (30nm) precision filtration effectively removes pathogens and suspended solids. The effluent turbidity is stably maintained below 0.05 NTU, which far exceeds international drinking water standards. Furthermore, our ceramic membranes are PFAS-free, ensuring no chemical or microplastic leakage into your water.
Q3: How does the Water Plant 3.0 System achieve such low energy consumption?
A: The Water Plant 3.0 utilizes our “Ultra-short Process” technology, which allows for direct filtration without the need for traditional heavy pretreatment. This simplified process reduces energy consumption from the industry average of 110 kWh/km³ to just 5 kWh/km³, representing a 95% saving in power costs.
Q4: What is the expected lifespan of a Cuiyuan Ceramic Membrane?
A: Thanks to the high-temperature sintering of inorganic materials (alumina and zirconia), our membranes are extremely wear-resistant and corrosion-resistant. The expected service life is over 20 years, making it a one-time investment for decades of reliable operation.
Q5: What is the water recovery rate of your system?
A: Our systems are designed for high efficiency and sustainability. The water recovery rate typically exceeds 98%, minimizing water waste and maximizing the utilization of your raw water source.
Q6: What are the maintenance requirements for these systems?
A: Cuiyuan water supply systems are designed for ease of use and low maintenance. They feature:
- Full Automation: Intelligent AI-driven control allows for stable, unattended operation.
- Self-Cleaning: Programmable automatic backwash and physical cleaning cycles prevent scaling and clogging.
- Durability: The inorganic material does not degrade or rot, requiring far fewer membrane replacements compared to organic systems.
Q7: Can the system handle highly turbid or challenging raw water?
A: Absolutely. Our ceramic membranes exhibit excellent resistance to oil, organic contamination, and high turbidity. They can filter highly turbid raw water directly while maintaining stable output and water quality, making them ideal for rivers, reservoirs, and even emergency water supply scenarios.
Q8: How does your technology contribute to environmental sustainability?
A: Sustainability is at the core of Cuiyuan’s solutions:
- Zero Waste: Used ceramic membrane materials are 100% recyclable into other ceramic products.
- Low Carbon Footprint: Extreme energy efficiency reduces CO2 emissions.
- Clean Technology: No chemical additives are required for the membrane structure itself, and the system is completely free of microplastics.
Q9: What is the footprint of a Water Plant 3.0 compared to traditional plants?
A: Due to the ultra-short process and modular design, the total project footprint is approximately only 25% of that required by conventional processes. This makes it an ideal solution for land-scarce urban areas or upgrading existing facilities.
