1.3 Core technology advantages
The structural design utilizes a capillary layout, enabling cross-flow filtration. Contaminants on the membrane surface are easily removed through backwashing, and the chemical cleaning cycle is up to 180 days per cycle. In terms of durability, the membrane filaments have a tensile strength of 157N per strand, and with normal maintenance, a service life of over 10 years is expected. The membrane also offers excellent energy efficiency, utilizing its low-pressure operating characteristics to reduce energy consumption by over 30% compared to traditional ultrafiltration membranes.

2.1 Technology Positioning
As an ultrafiltration membrane designed specifically for extreme working conditions, it is primarily suitable for demanding applications such as high pollution, strong chemical corrosion, and high temperatures. Together with the PVC alloy capillary ultrafiltration membrane, it forms a complementary product system encompassing “general scenarios + special scenarios” to meet diverse water treatment needs.
2.2 Core Technical Parameters
The nominal pore size is 0.02μm, and the transmembrane pressure is 0.06-0.10MPa. The pH tolerance range extends to 1-14, allowing it to withstand both strongly acidic (e.g., 5% hydrochloric acid) and strongly alkaline (e.g., 10% sodium hydroxide) water. The water temperature range is 5-50°C, allowing it to treat high-temperature industrial wastewater. It can withstand long-term residual chlorine concentrations of ≤5000ppm, eliminating the need for additional dechlorination steps. The membrane has a tensile strength of 200N per strand, and the produced water turbidity is ≤0.2NTU, meeting industrial water standards.

2.3 Core Technology Advantages
The structure adopts a three-layer composite support design of “reinforced fiber + PVDF base membrane + anti-pollution coating”. Even under the high-pressure backwash condition of 0.15MPa, the wire breakage rate is still less than 0.1%; the anti-pollution performance is outstanding, and the membrane surface is covered with a nano-scale anti-pollution coating (contact angle ≤ 60°), which reduces the adsorption of organic matter and colloids, and the chemical cleaning cycle is extended to 270 days/time; it has strong weather resistance, does not crack at low temperatures of -20℃, and does not soften at high temperatures of 50℃, and can stably cope with extreme temperature and chemical corrosion scenarios.

Functions of Smart Water System
1. Full-process monitoring and early warning
• Real-time sensing: Covering water sources, water plants, pipeline nodes, and user terminals, it dynamically monitors water quality safety indicators (such as turbidity and microorganisms) and equipment health.
• Intelligent early warning: Configurable multi-level thresholds automatically trigger alerts via SMS, audio, and visual notifications when parameters exceed standards or equipment anomalies occur. Response time is ≤ 30 minutes.
• GIS visualization: Combined with electronic maps, it recreates monitoring point scenarios and supports manual and automatic inspections of water conservancy facilities.
2. Refined operations management
• Intelligent Scheduling: Optimizes pump operation based on water load forecasts, reducing energy consumption by over 15%.
• Leakage Control: Identifies leakage hotspots through pressure data analysis and clustering algorithms, reducing leakage rates to below 10%.
• Remote Control: Supports manual, automatic, and remote control modes for pumps, valves, and other equipment to adapt to different operating conditions.
3. Full lifecycle data management
• Automatically stores operational data and generates trend curves, supporting query, export, and traceability analysis.
• Builds equipment profiles to record installation time, maintenance history, and fault records for predictive maintenance.
• Utilizes SSL/TLS encrypted transmission and tiered authorized access to ensure data security (data integrity ≥ 99%).
Typical application scenarios
1. Improvement of rural water supply
In projects such as the ancient water plant in Dinghu District, Zhaoqing, Guangdong, the “small smart water plant + pipe network terminal monitoring” model addresses the problems of small water supply scale and dispersed users in remote areas, enabling direct drinking water access to villages and households, serving more than 5,000 villages and towns across China.
2. Industrial wastewater treatment
We provide water reuse solutions for eight major industries, including glass grinding and electroplating. For example, our Changsha glass grinding wastewater treatment project has a treatment capacity of 50,000 m³/d, saving over 30% of land compared to traditional processes.
3. Overseas water supply projects
Nearly 4,000 small and medium-sized water supply projects have been built in countries such as Japan and Australia, of which 3,300 projects in Japan have adapted to the complex water source conditions of islands through intelligent management.
