Ultrafiltration System and Equipment for Industrial Water Reuse Projects

Ultrafiltration system and equipment represents the complete membrane separation assembly applied in water purification, wastewater recycling and desalination pretreatment. It can be flexibly matched with Water treatment ultrafiltration equipment for medium-scale purification projects, and cooperate with Membrane ultrafiltration equipment to construct modular deep treatment workflows. Based on low-pressure cross-flow filtration principles, this set of facilities reliably intercepts suspended solids, colloids, microorganisms and macromolecular organics with low chemical consumption. Available in standardized skid-mounted models and customized non-standard units, ultrafiltration system and equipment remains a preferred membrane solution for global engineering contractors engaged in municipal and industrial water treatment.

Product Description

Ultrafiltration system and equipment covers the whole set of hardware including core membrane modules, power assemblies, pipeline manifolds, cleaning units and automatic control cabinets. Distinguishing between the ultrafiltration system (complete process flow) and standalone equipment (single functional unit), this product portfolio supports flexible collocation according to project water yield and raw water quality. Customers can select independent Water treatment ultrafiltration equipment for small-capacity water supply demands, or adopt integrated Membrane ultrafiltration equipment to assemble large-scale continuous processing systems.

The mainstream configuration adopts PVDF hollow fiber membrane modules, while tubular membrane alternatives are available for wastewater containing high suspended solids and oily pollutants. The full assembly includes raw water feed pumps, security filters, ultrafiltration membrane racks, backwashing pipelines, chemical dosing systems and PLC control panels. All pipelines and frames can be customized with carbon steel anti-corrosion coating or stainless steel materials. Ultrafiltration system and equipment adapts to surface water, groundwater, municipal secondary effluent and light industrial wastewater. Widely deployed in food processing, pharmaceutical manufacturing, electronic production and chemical industries, it supplies stable qualified inlet water for subsequent reverse osmosis desalination systems.

Working Principle

Ultrafiltration system and equipment operates on cross-flow ultrafiltration separation technology. Driven by circulating pumps under 0.1–0.3 MPa operating pressure, raw water flows through ultrafiltration membrane elements. Water molecules and soluble small inorganic ions penetrate membrane micropores to form clean permeate water. Contaminants larger than membrane pore sizes, such as colloids, bacteria, algae and organic macromolecules, are trapped on the membrane surface and discharged along with concentrated water.

Persistent cross-flow generates surface scouring shear force to reduce pollutant accumulation and slow membrane fouling. The intelligent control system automatically triggers regular backwashing. When flux declines significantly, periodic online chemical cleaning restores membrane permeability. For small-scale projects, users can deploy compact Water treatment ultrafiltration equipment. Large engineering projects usually combine multiple groups of Membrane ultrafiltration equipment to build parallel ultrafiltration system and equipment, realizing capacity expansion without redesigning the whole process.
