Are you still worried about the water quality of municipal water supply?
The rapid increase in urban population has led to a shortage of high-quality water sources, traditional processes are difficult to remove trace pollutants, secondary pollution in pipelines affects the terminal water quality, and special industries (such as medical care and schools) have an urgent need for pure water... Have these problems put your municipal water supply project in trouble?
Now, our municipal reverse osmosis equipment has brought about a disruptive breakthrough: with high-precision membrane separation technology as the core, combined with an intelligent system to achieve fully automatic operation, it improves water quality standards from the source, meets multiple needs such as direct drinking for residents, industrial supporting facilities, and emergency water supply, and ensures that every drop of municipal water supply can stand the test.
Core advantage: Redefining municipal water supply quality standards
1. 99.9% pollutant removal rate, water quality reaches drinking water level standard
Adopt imported Dow/Hydroxy RO membrane elements , through high-precision filtration with 0.0001 micron pore size:
Deeply remove heavy metals (lead, cadmium, mercury), organic matter (pesticide residues, industrial pollutants), microorganisms (bacteria, viruses) and dissolved salts in water, with effluent TDS ≤ 50mg/L
It complies with all indicators of the "Healthy Standard for Drinking Water" (GB 5749-2022) and can be directly supplied as drinking water without the need for secondary treatment.
For special water sources such as high-fluoride water and brackish water, the fluoride removal rate is ≥95% and the desalination rate is ≥98%, which completely solves the regional water quality problems.
2. Modular design to meet all municipal needs
Breaking the fixed limitations of traditional water purification plants, equipment can be flexibly combined:
The treatment scale covers 50m³/d-5000m³/d. A single set of equipment can meet the water needs of 300-30,000 people. Multiple sets in parallel can serve large towns.
It can be used in the deep treatment process of water plants, community water supply stations, industrial park supporting facilities, and even as a core component of emergency mobile water purification vehicles.
It occupies only 1/4 of the space of traditional technology and can be installed indoors or in container-type outdoor spaces. It can operate stably in both extremely cold and high temperature areas.
3. Intelligent low-consumption operation reduces municipal operating costs
Equipped with AI adaptive control system to achieve a precise balance between energy efficiency and water quality:
Automatically adjusts water inlet pressure and recovery rate (60%-75% adjustable), energy consumption per ton of water ≤1.2kWh, 15% lower than traditional reverse osmosis equipment
Real-time monitoring of membrane contamination levels and intelligent start of cleaning procedures extend membrane life to 3-5 years, reducing replacement costs
Supports networking with the municipal water supply system, remote monitoring of water production and water quality indicators, automatic alarm for abnormal situations, and reduces the frequency of manual inspections
4. Double membrane method for deep treatment to meet complex water source challenges
Adopt UF+RO dual membrane process combination to strengthen pretreatment guarantee:
Ultrafiltration membrane pretreatment removes colloids, suspended solids, and macromolecular organic matter, reduces the risk of RO membrane contamination, and improves system stability
It can tolerate the fluctuation of influent turbidity ≤10NTU and SDI ≤5. Even if the raw water quality deteriorates, it can still stably produce high-quality water.
Equipped with concentrated water recovery system, the discharged water is reprocessed for municipal greening and road cleaning, thus improving the utilization rate of water resources.
5. Durable and impact-resistant, with a 20-year life cycle guarantee
The main body of the equipment adopts 304 stainless steel frame + fiberglass membrane shell , and the core components are selected from top brands in the industry:
Resistant to residual chlorine, acid and alkali corrosion in municipal raw water, the service life of the main equipment is ≥20 years
Equipped with an emergency backup system, it automatically switches to the backup unit when a single membrane element fails, ensuring uninterrupted water supply
Support phased expansion. As urban water demand grows, the number of membrane modules can be gradually increased to avoid initial over-investment.
Applicable scenarios: Covering all areas of municipal water supply needs
Deep treatment of water plants : As an upgrade of traditional processes, it solves the problem of excessive organic matter and heavy metals in factory water.
Township Safe Drinking Water Project : Treating low-quality water sources such as high-fluoride water and brackish water to ensure safe drinking water for residents in remote areas
Municipal emergency water supply : After disasters such as earthquakes and floods, mobile reverse osmosis equipment is quickly deployed to ensure temporary drinking water safety
Special industry support : providing direct drinking water for hospitals, schools, and government agencies, and providing production water for food processing and pharmaceutical companies
Improve the quality of water at the end of the pipe network : Set up water supply stations with different qualities in old pipe network areas to solve the problem of substandard terminal water quality caused by secondary pollution
Working principle: Scientific technology ensures ultimate purity
Pretreatment system : The raw water is first filtered through quartz sand to remove sediment, activated carbon absorbs organic matter and residual chlorine, and ultrafiltration membrane intercepts colloids and microorganisms to provide qualified water for RO membrane
High-pressure pump pressurization : The pre-treated water is pressurized to 1.0-1.5MPa by a high-pressure pump and enters the RO membrane assembly
Reverse osmosis separation : Water molecules pass through the RO membrane to form produced water, while dissolved salts and pollutants are intercepted and discharged as concentrated water (concentrated water can be recycled)
Post-treatment : The produced water is disinfected by ultraviolet light and minerals are added (optional), and the taste is adjusted before entering the water supply system.
Intelligent control : Sensors monitor the TDS, flow rate, and pressure of produced water in real time, and the control system automatically adjusts operating parameters to ensure stable compliance with standards.
Customer Case: Successful Practice of Municipal Water Supply Upgrade
Inner Mongolia High-Fluoride Water Treatment Project : The groundwater fluoride content in a certain county reached 3.2mg/L. After using a 200m³/d reverse osmosis device, the fluoride content in the effluent was reduced to below 0.5mg/L, solving the drinking water safety problem for 5,000 local residents. The equipment has been in continuous operation for three years without any problems.
Jiangsu's direct drinking water project for older residential communities : To address substandard water quality at the end point caused by secondary contamination of the pipe network, 10 residential communities were equipped with 50m³/d quality-differentiated water supply equipment, allowing residents to drink directly. The project achieved a 98% satisfaction rate, with an annual maintenance cost of only RMB 20,000 per community.
Sichuan Earthquake Emergency Water Supply : After the earthquake, the tap water system was paralyzed. Two 100m³/d mobile reverse osmosis equipment were urgently deployed. Water supply was restored within 48 hours, providing safe drinking water to 2,000 people in the disaster area. The equipment operated stably for one month in extreme conditions.
