Introduction
From turbid river water to high-solids industrial effluents, diverse fluid compositions require targeted purification. LEFILTER Adaptive Ultrafiltration Systems deliver precision with 0.03–0.1μm membranes, offering switchable full-flow (energy-efficient, high recovery) and cross-flow (fouling-proof, robust for dirty fluids) modes. Scalable across 1–200 m³/h capacities, they purify drinking water, recycle textile/dyeing wastewater, concentrate biopharmaceuticals, and treat municipal sewage—all while retaining beneficial minerals or solutes. LeFilter’s on-demand design ensures perfect alignment with unique project needs, minimizing waste and maximizing operational efficiency.
l Drinking water, ultra filtration only removes suspended solids,colloidal particles, bacteria and other impurities in the water, and retains the minerals thatare beneficial to human health.
l Municipal,family,school,restaurant,hotel,commercial,rural water;pure water before/after treatment.
l Desalination, pharmaceutical water, chemical industry pure water system, biological engineering system, food and beverage pure water system.
l Water, sewage, waste water treatment and reuse.
l Oily wastewater, heavy metal wastewater, textile printing and dyeing wastewater, paper industry wastewater,municipal sewage treatment.
l Special solution separation and concentration.
l Concentration and separation of biotechnology, purification of Chinese medicine preparation, concentration and removal of impurities, starch recycling applications, food and beverage concentration and clarification applications.
Tworking Principle
During the ultrafiltration process, the aqueous solution flows through the membrane surface under pressure. The solvent (water) and small molecular solutes smaller than the membrane pores permeate the membrane and become purified liquid (filtrate), while the solutes larger than the membrane pores are retained and discharged with the water flow to become concentrated liquid.
There are two modes of ultrafiltration operation: full-flow filtration (dead-end filtration) and cross-flow filtration.
In full-flow filtration, all the influent water passes through the membrane surface to become produced water; while in cross-flow filtration, part of the influent water passes through the membrane surface to become produced water, and theotherpart isdischarged with impurities to become concentrated water.Fullflow filtrationhas lowenergy consumption and high recovery rate,so the operating cost is lower; while cros-flow filtration can treat fluids with higher suspended matter content. The specific operation mode should be determined according to the suspended matter contentin the water.
Product Features
l The separation process does not cause phase change, and does not cause changes in temperature and pH,thus preventing the denaturation, inactivation and autolysis of biomacromolecules;
l The separation process can be crried out atnormal temperature and consumes litle energy;
l The separation process is driven only by low pressure, the equipment and process flow are simple, the cost is low, no chemical reagentsare required, and it is easy to operate, manage and maintain;
l The application range is wide. Ultrafiltration separation technology can be used for solutes with molecular weights of 1000~500000 Daltons or solute sizes of about 0.03-0.1um.
