Our 15 ton ultrafiltration equipment refers to the unit with 15 tons per hour permeate water yield, designed as an integrated skid-mounted structure, taking modified hydrophilic PVDF hollow fiber ultrafiltration membrane as the core filtering component. The complete set of standard 15-ton UF equipment consists of hollow fiber membrane module groups, SUS304 stainless steel integral frame, raw water booster pump, automatic backwash pipeline assembly, online acid-alkali chemical cleaning system, front security liquid filter and PLC intelligent automatic control cabinet. As the essential front-end protective equipment of reverse osmosis host, this 15 ton ultrafiltration system can effectively intercept suspended solids, colloids, algae, bacteria and macromolecular organic pollutants in raw water, steadily keep the SDI value of produced water below 5, greatly reduce RO membrane pollution, scaling and chemical cleaning frequency, and extend the service life of expensive reverse osmosis membrane elements. All finished 15-ton ultrafiltration equipment will pass air tightness pressure test and 72-hour full-load continuous operation aging test before delivery to adapt to long-term non-stop operation under industrial working conditions.
We launch differentiated ultrafiltration products to satisfy different project demands. Customers with basic pure water demands can select the cost-effective Hollow Ultrafiltration Equipment for Industrial Water Purification based on the 15-ton benchmark model. For complete packaged water treatment stations, the integrated Ultrafiltration UF System for Industrial Water Treatment realizes centralized automatic control and reduces field installation workload for construction parties. For large factory parks with peak water consumption, users can upgrade to the enhanced High Performance Industrial Ultrafiltration Equipment with enlarged membrane area. For printing & dyeing, chemical wastewater advanced treatment, the anti-fouling optimized Ultrafiltration Water Reuse can realize wastewater resource recovery. For outdoor open installation and harsh ambient conditions, the anti-corrosion Durable Ultrafiltration Equipment upgrades frame and pipe materials to prolong overall service life.
The frame and pipeline of standard 15 ton ultrafiltration equipment adopt SUS304 stainless steel; SUS316L stainless steel and FRP pipeline are supported for customized production when dealing with high-salinity and corrosive raw water. The built-in PLC touch screen system realizes real-time differential pressure monitoring, timed automatic backwashing, fault alarm and remote data viewing functions, effectively reducing daily manual operation and management pressure. We provide spot supply of standard 15-ton ultrafiltration equipment, non-standard size customization, OEM processing and export certification documents to help overseas customers smoothly complete customs clearance in various countries and regions.
Our 15 ton ultrafiltration equipment applies mature pressure-driven cross-flow physical interception principle, and the whole operating cycle is divided into three core working states: normal water production filtration, automatic backwashing and periodic chemical cleaning.
After preliminary filtration by multimedia filter and 5μm security filter, raw water is transported into the inner cavity of hollow fiber membranes under the pressure of the feed pump. The aperture of the ultrafiltration membrane is fixed at 0.01~0.1μm. Water molecules and tiny soluble substances penetrate the membrane wall to form qualified permeate water, which flows into the intermediate water tank for subsequent reverse osmosis desalination treatment. Solid particles, colloids and microorganisms are trapped inside the membrane tube or attached to the membrane surface. The tangential high-speed flow of raw water continuously scours the membrane surface to slow down the accumulation of pollutant filter cake and maintain stable water yield flux during long-term operation.
With the continuous accumulation of intercepted pollutants, the pressure difference between the inlet and outlet of membrane modules will gradually rise. Once the numerical value reaches the preset threshold of the control system, the electric valve will switch automatically. Clean produced water carries out reverse flushing on hollow fiber filaments to wash away loose pollutants, and concentrated sewage is discharged outward. The backwashing process only takes a short period and will not cause long-time shutdown of the whole water treatment system.
Long-term physical backwashing cannot completely remove biological slime, organic attachments and slight inorganic scale deposited inside membrane pores. The matched dosing system uses diluted acid and alkali solution for circulating soaking cleaning to thoroughly restore the original flux of ultrafiltration membranes and maintain the equipment in high-efficiency and energy-saving operation state for a long time.
