Small ultrafiltration membrane equipment is miniaturized lightweight ultrafiltration treatment equipment developed aiming at low water volume demand users, generally with single set water production ranging from 0.5 tons to 10 tons per hour. The core filter element uses hydrophilic modified PVDF hollow fiber ultrafiltration membrane, matched with miniature stainless steel frame, small flow feed pump, manual/automatic backwash pipeline, simple dosing cleaning unit, front security liquid filter and compact electric control cabinet. It abandons the huge frame and large-caliber pipeline of large industrial ultrafiltration equipment, adopts integrated compact layout, can be placed indoors or simple outdoor shelters directly, realizing plug-and-play installation without complex civil construction.
This small membrane equipment can purify raw water, treat domestic sewage and small production wastewater, effectively intercept bacteria, colloids, rust, suspended particles and macromolecular organic matter in water body, stabilize produced water SDI below 5, which can be used as pretreatment water for small reverse osmosis systems or direct reuse water for cleaning and flushing. All finished small ultrafiltration membrane equipment will pass air tightness test and 48-hour continuous running test before delivery to guarantee stable operation under low-flow working conditions.
We provide graded small ultrafiltration products to meet differentiated small-flow treatment needs. Users who need unattended operation can select the mini version of Fully Automatic Ultrafiltration Equipment for Industrial Water with automatic backwash program; ordinary domestic water purification and small workshop water supply adopt cost-effective Ultrafiltration Membrane Water Purification Equipment small models; users who need pure water preparation can combine with reverse osmosis through Ultrafiltration and Reverse Osmosis Device supporting small-sized matched units; limited installation space is suitable for plate structure High Efficiency Plate Ultrafiltration Equipment; small batch material concentration and sewage separation can choose mini Integrated Ultrafiltration and Nanofiltration Equipment for Water Treatment.
The standard frame and pipeline of small ultrafiltration equipment are SUS304 stainless steel material; PP plastic pipeline can be selected for low-cost civilian scenarios. Control modes are divided into manual control and PLC automatic control according to customer requirements. Our factory supports spot sales of standard small ultrafiltration equipment, customized membrane quantity, water flow size and cabinet layout, and provides complete CE export certification documents for overseas small engineering projects.
Small ultrafiltration membrane equipment adopts pressure-driven cross-flow filtration principle, and the whole operation cycle is divided into three circulating working modes: normal water production filtration, backwash cleaning and regular chemical cleaning.
Raw water enters the hollow fiber membrane tube under the pressure of the small feed pump. The membrane pore size is fixed at 0.01~0.1μm. Water molecules and tiny soluble substances penetrate the membrane wall to form clean produced water for use. Impurities such as suspended solids, colloids and microorganisms are trapped on the inner wall of the membrane filaments. The cross flow of raw water continuously scours the membrane surface to reduce the accumulation of dirt and maintain stable water output.
As the dirt accumulates, the system pressure difference rises gradually. Users can start manual backwash regularly, or the automatic model will trigger backwash according to the set time. Clean produced water flows reversely into the membrane tube to flush loose dirt on the membrane surface, and dirt is discharged out of the equipment with concentrated water. The whole process takes only 3–8 minutes and will not affect long-term water supply.
Long-term operation will form stubborn organic dirt and biological slime on the membrane surface. The small dosing tank is matched to prepare dilute acid and alkali solution for circulating soaking cleaning, restore the original flux of the small membrane component and prolong the service life of the ultrafiltration membrane.

Q4: What pretreatment needs to be equipped before the inlet of small ultrafiltration membrane equipment?
A: It is recommended to install a simple quartz sand filter + security liquid filter at the front end to intercept large particles of sediment and impurities, avoid scratching the membrane filaments and reduce the pollution load of the ultrafiltration membrane.
Q5: What parts are covered by the factory warranty of small ultrafiltration membrane equipment?
A: Stainless steel frame, water pump, valve body and control electrical components enjoy a 1-year factory global warranty; ultrafiltration membrane elements are consumables and are not within the warranty scope.
Q6: Can multiple sets of small ultrafiltration membrane equipment be used in parallel to increase the total water production capacity?
A: Completely feasible. Multiple small units can be connected in parallel on the main water pipeline for combined water production, which is convenient for users to gradually expand water treatment capacity according to the growth of water demand.
