Membrane Ultrafiltration Equipment for Industrial & Municipal Water Purification

Membrane ultrafiltration equipment is a high-precision physical water treatment system that uses polymer membrane micropore separation technology to remove micro-pollutants from various raw water sources. It can be perfectly customized and supplied by professional Manufacturer of ultrafiltration membrane water purification equipment, and flexibly matched with standard UF ultrafiltration equipment to build multi-stage water purification processes. Adopting low-pressure cross-flow filtration, this equipment effectively intercepts suspended solids, colloids, bacteria and macromolecular organics without excessive chemical dosing. With stable effluent quality and low operation cost, membrane ultrafiltration equipment has become the core membrane filtration solution widely used in industrial water production, wastewater reuse and desalination pretreatment projects worldwide.

Product Description

Membrane ultrafiltration equipment refers to integrated water treatment facilities that take ultrafiltration membrane elements as the core purification component. Different from traditional sand filtration and carbon filtration devices that only remove large particles, membrane ultrafiltration equipment achieves molecular-level precise filtration. The complete system includes raw water lift pump, multi-stage pre-filter units, membrane module rack, automatic backwashing pipeline, chemical cleaning dosing system and intelligent PLC control cabinet.

This equipment covers multiple series including hollow fiber type and tubular type to adapt to different water quality conditions. Users who need standardized and cost-effective solutions can choose conventional assembledUF ultrafiltration equipment. For projects requiring personalized design, special size adjustment and high-standard quality control, customers can cooperate directly with a professional Manufacturer of ultrafiltration membrane water purification equipment for non-standard customization. Membrane ultrafiltration equipment is suitable for surface water, groundwater, municipal secondary sewage effluent and medium-light industrial wastewater. It is widely applied in food and beverage production, pharmaceutical processing, electronic manufacturing, chemical industry and municipal environmental protection, providing stable and qualified pretreatment water for reverse osmosis pure water systems.

Working Principle

Membrane ultrafiltration equipment operates based on mature low-pressure cross-flow membrane separation principle. Under a stable operating pressure of 0.1 MPa to 0.3 MPa, raw water uniformly flows through the surface or inside of ultrafiltration membrane filaments. Water molecules and soluble tiny inorganic ions smoothly pass through the micron-scale membrane pores to form clean permeate water that meets industrial and domestic water standards.

Pollutants with larger particle sizes, such as suspended solids, colloids, algae, bacteria and macromolecular organic substances, are firmly intercepted by the membrane layer and continuously discharged with concentrated water. The cross-flow circulating water flow forms persistent scouring force on the membrane surface to reduce pollutant deposition and delay membrane fouling. The system automatically performs timed backwashing and periodic chemical cleaning to restore membrane flux and ensure long-term stable operation. According to project scale and water quality complexity, users can select ready-to-use UF ultrafiltration equipment or customize exclusive systems through reliable Manufacturer of ultrafiltration membrane water purification equipment to maximize purification efficiency and operation stability.
