Filtering Equipment Ultrafiltration for Graded Industrial Water Treatment

Filtering equipment ultrafiltration combines conventional pre-filter units and ultrafiltration membrane separation technology to deliver graded, high-precision water purification for industrial and municipal water projects. It can work in tandem with Ultrafiltration membrane device to strengthen core filtration capacity, and integrate seamlessly with Ultrafiltration equipment system to build standardized full-process water treatment lines. This combined filtering solution removes coarse particles and micro-pollutants step by step, minimizing membrane fouling and extending the service cycle of membrane components. Preferred by global environmental engineering firms, filtering equipment ultrafiltration is widely deployed for raw water treatment, wastewater reuse and desalination pretreatment across numerous manufacturing sectors.

Product Description

Filtering equipment ultrafiltration represents a composite water treatment configuration integrating preliminary filtering machinery and ultrafiltration membrane filtration units. Traditional filtering equipment such as multi-media filters and security filters intercept large suspended impurities, while ultrafiltration modules achieve precision separation of colloids, bacteria and organic macromolecules. This graded design eases the pollution burden on membrane elements and avoids frequent flux attenuation caused by direct exposure of membranes to untreated raw water.

The complete assembly consists of raw water pumps, pre-filter vessels, pipeline manifolds, core ultrafiltration components, backwashing assemblies and automatic control cabinets. Project designers can adopt independent Ultrafiltration membrane device as the core filtration unit according to required water yield. For large-scale water plants, multiple sets of filtering equipment and ultrafiltration modules can be combined into a unified Ultrafiltration equipment system. This filtering equipment ultrafiltration setup adapts to surface water, groundwater, municipal secondary effluent and low-to-medium contaminated industrial wastewater. It supplies qualified inlet water for reverse osmosis systems and serves water purification demands in food, pharmaceutical, chemical, electronics and municipal environmental protection industries.

Working Principle

Filtering equipment ultrafiltration operates following a two-stage purification logic. In the first phase, raw water flows through filtering equipment to trap sediment, rust and large suspended solids, completing primary clarification and lowering the pollutant load for subsequent procedures. After pretreatment, the water enters ultrafiltration facilities under low cross-flow pressure ranging from 0.1 MPa to 0.3 MPa.

Water molecules and soluble small inorganic ions pass through ultrafiltration membrane micropores to generate purified product water. Contaminants exceeding membrane pore sizes, including colloids, microorganisms and organic macromolecules, are intercepted and discharged via concentrated water pipelines. Continuous cross-flow creates scouring force to reduce pollutant accumulation on membrane surfaces. Timed automatic backwashing and periodic chemical cleaning recover membrane permeability. For flexible capacity planning, users can select single Ultrafiltration membrane device for small-flow scenarios or combine multiple units into a complete Ultrafiltration equipment system to satisfy high-flow industrial and municipal water treatment demands.
