Product Overview:
The ultrafiltration equipment, developed based on UF ultrafiltration membrane screening technology, is a low-pressure high-precision water purification device. It is commonly used for the deep purification of tap water, groundwater, and surface water. It
Working Principle
The ultrafiltration equipment adopts a low-pressure cross-flow filtration process, relying on the pore size of the ultrafiltration membrane to achieve physical screening and purification. Under the push of low-pressure water flow, water molecules and soluble small molecular minerals smoothly pass through the membrane fibers, while impurities such as sediment, suspended solids, colloids, algae, bacteria, macromolecular organic matter, and insect eggs in the water are completely retained, achieving precise solid-liquid separation.
The equipment adopts a cross-flow filtration + automatic flushing structure. The high-speed water flow scours the surface of the membrane fibers, effectively reducing the accumulation of impurities. Coupled with the timed automatic backwash and forward wash processes, it can maintain stable membrane flux for a long time, making it less prone to membrane blockage and attenuation. It is suitable for long-term continuous high-flow water purification operations.
Device Configuration
The entire machine is integrated and assembled in a compact layout, occupying a small area and facilitating easy installation. The core components are carefully selected and adapted for long-term industrial operation. The core configuration is as follows:
- Pre-treatment system: Equipped with standard PP cotton precision filtration, activated carbon filtration, and cartridge filtration, and optionally equipped with quartz sand and softening filtration, it intercepts large particles of impurities in advance, protecting the ultrafiltration membrane components and significantly reducing the probability of membrane fouling.
- Low-pressure boosting system: Equipped with an energy-saving and silent centrifugal pump, it operates at low pressure, delivers abundant water output, consumes less energy, produces low operating noise, maintains stable pressure, and meets the demand for high-throughput continuous water production.
- Hollow fiber ultrafiltration membrane module: Utilizing external/internal pressure type anti-pollution ultrafiltration membranes, it boasts high flux, strong toughness, wash resistance, oxidation resistance, uniform retention accuracy, and can be repeatedly regenerated through water washing. It has a long service life and low operating costs.
- Intelligent PLC control system: Fully automatic touch operation, supporting automatic water production, scheduled flushing, differential pressure monitoring, fault alarm, and water shortage protection. No need for dedicated personnel to monitor, and it can be integrated with remote monitoring systems for real-time visibility of equipment status.
- Stainless steel body pipeline: The frame, pipeline, and filter tank body are made of SS304 stainless steel, which is corrosion-resistant, rust-proof, pressure-resistant, and washable, without secondary pollution. It is suitable for complex working conditions such as humid environments, outdoor settings, and industrial workshops.
- Optional supporting systems: It can be equipped with chemical dosing, ultraviolet sterilization, precision security filtration, and clean water storage system, suitable for higher water quality requirements and reclaimed water reuse conditions.
Product Advantages
High-flux low-pressure filtration, yielding clear and stable water
The ultrafiltration membrane precisely intercepts impurities such as colloids, suspended solids, bacteria, and algae, effectively solving the problem of turbid and yellow water. With low-pressure operation, it has a large flux, fast water production speed, and uniform and stable effluent quality, meeting the demand for continuous high-flow water supply.
Resistant to pollution and easy to regenerate, with a long service life
Utilizing cross-flow filtration technology combined with an automatic flushing process, impurities are less likely to accumulate and clog the membrane. The membrane components can be regenerated and restored to their original flux through water washing, eliminating the need for frequent filter cartridge replacement. Compared to traditional filtration equipment, it boasts a longer service life and higher stability.
Energy and water saving, with extremely low operating costs
Operating at low pressure throughout the process, without the need for high-pressure boosting, its energy consumption is significantly lower than that of reverse osmosis equipment. It boasts a high recovery rate of pure water, produces minimal wastewater, and utilizes water resources efficiently. There is no need for frequent consumable replacement in daily operation, making long-term operation and maintenance costs economical and affordable.
Fully automated operation, hassle-free operation and maintenance
The equipment features one-button start/stop, automatic water production, automatic flushing, fault self-inspection, multiple safety protection functions, and supports 24-hour uninterrupted continuous operation, significantly reducing manual operation and maintenance costs.
Wide adaptability, customizable selection
Equipment specifications can be customized according to the quality of raw water, treatment capacity, and usage scenarios. Integrated, skid-mounted, and outdoor models are supported. It can be used for water purification alone or as a supporting system for the pre-treatment of reverse osmosis equipment.
