The ultrafiltration water system is a core solution designed to achieve efficient recycling of water resources. This system integrates advanced ultrafiltration membrane technology and intelligent control system, which can accurately treat raw water such as production and domestic sewage to meet the standards of reclaimed water reuse, with water turbidity ≤ 0.2NTU and suspended solids removal rate of over 99.9%. The system adopts a modular design, reducing the footprint by 30% compared to traditional processes, and adapting to the needs of projects of different scales. The daily processing capacity can be flexibly adjusted from 500 tons to 50000 tons, helping enterprises and parks build a green and water-saving water use system, significantly reducing the cost of fresh water intake and sewage discharge.
System Principles
The system is based on a hollow fiber ultrafiltration membrane with a pore size of 0.01-0.1 microns, forming a dual filtration mechanism of physical screening and deep adsorption. After pre-treatment to remove large particle impurities, the raw water is driven by a low pressure of 0.1-0.3 MPa. Water molecules and small molecule substances pass through the membrane pores to become clean produced water, while colloids, microorganisms, large molecule organic matter, suspended solids and other impurities are effectively intercepted. Combined with self-developed cross flow filtration technology, the membrane surface flow rate is controlled at 1.5-2.5m/s to reduce pollutant deposition. Combined with timed chemical enhanced backwashing (CEB) process, the membrane flux attenuation rate is ≤ 5% per month, ensuring long-term stable operation of the system and achieving efficient and low consumption water purification.
Dealing with difficulties
In response to the industry pain points of complex pollutant composition (CODcr 50-300mg/L, ammonia nitrogen 5-50mg/L fluctuation) and difficult membrane pollution control in reclaimed water reuse, Waterland Innovation adopts composite modified ultrafiltration membrane materials, which increase surface hydrophilicity by 40%, enhance anti pollution ability by 60%, and reduce the adsorption rate of typical pollutants such as humic acid and protein by 70%. At the same time, an intelligent monitoring system is built to collect more than 20 parameters such as inlet water quality (pH, conductivity, turbidity), operating pressure, and water production in real time. Through AI algorithms, the filtration cycle and cleaning strategy are dynamically adjusted, extending the membrane chemical cleaning cycle to twice that of traditional processes (up to 60-90 days), significantly reducing maintenance costs and downtime, and ensuring stable treatment effects even in high load and water quality fluctuation scenarios.
Application Industry
The system is widely used in industrial manufacturing (such as production process water and cooling cycle water reuse in the electronics, power, chemical, and steel industries), municipal water management (deep treatment of municipal sewage, rainwater collection and reuse), commercial buildings (office buildings, hotel flushing, green irrigation water), landscaping (landscape water replenishment in scenic spots and parks) and other fields. We have successfully served 50+industrial enterprises and 30+municipal projects, helping our clients achieve a water resource reuse rate of 70% -90%, saving over 10 million tons of water resources annually, equivalent to the daily water consumption of 1 million people. This significantly improves our clients' environmental and economic benefits, making us the preferred solution for water conservation, emission reduction, and green development in various industries.
