Ultrafiltration Separation Equipment for Industrial Membrane Water Treatment

Ultrafiltration separation equipment is a membrane-based separation facility that separates substances according to molecular weight cutoff, widely used for water purification, material concentration and wastewater advanced treatment. It can work together with Ultrafiltration system and equipment to build large-scale treatment stations, and coordinate with Water treatment ultrafiltration equipment to realize graded pollutant interception. Under low cross-flow pressure, the equipment retains colloids, microbes and macromolecular organics while allowing water molecules and small soluble ions to pass through. Owing to its physical separation mechanism, low energy demand and easy automatic operation, ultrafiltration separation equipment has become a preferred technology for environmental protection, food processing and chemical engineering projects around the world.

Product Description

Ultrafiltration separation equipment takes ultrafiltration membrane modules as the core separation medium to achieve selective separation of mixed liquid systems. Different from conventional filtration devices that only trap large particles, it relies on precise molecular weight cutoff to realize classified separation of dissolved substances and suspended pollutants. The complete set consists of feed pump, circulating pump, membrane housing, ultrafiltration membrane elements, backwashing pipeline, chemical cleaning assembly and PLC control cabinet.

For small-flow purification demands, customers can adopt compact Water treatment ultrafiltration equipment. For large engineering projects, multiple groups of equipment can be combined into integrated Ultrafiltration system and equipment to boost overall processing capacity. Available membrane materials include PVDF, PAN and PES hollow fiber membranes, and tubular membrane options are provided for wastewater with high suspended solids. Ultrafiltration separation equipment is suitable for surface water, groundwater, municipal secondary effluent and light industrial wastewater. It can be applied not only in water treatment, but also in food clarification, biological liquid concentration and pharmaceutical liquid purification, providing reliable separation performance for multiple industrial sectors.

Working Principle

Ultrafiltration separation equipment follows low-pressure cross-flow membrane separation theory. Driven by circulating pumps at 0.1–0.3 MPa, raw liquid flows along the surface of ultrafiltration membrane components. Water molecules and small inorganic ions with molecular weight below the membrane cutoff value penetrate the membrane micropores to form permeate liquid. Substances larger than the membrane pore size such as suspended solids, colloids, bacteria and macromolecular organics are intercepted on the membrane surface and discharged with concentrated fluid.

Continuous cross-flow creates shear force on the membrane surface, reducing pollutant accumulation and slowing membrane fouling. The automatic control system executes scheduled backwashing; when flux drops obviously, online chemical cleaning restores membrane permeability. According to project scale and fluid characteristics, users can select single-set Water treatment ultrafiltration equipment, or assemble multiple units into complete Ultrafiltration system and equipment. Reasonable pretreatment configuration can effectively reduce membrane pollution load and extend the continuous operation cycle of ultrafiltration separation equipment.
