Compact Small Ultrafiltration Device for Pilot Test & Onsite Water Purification

Small ultrafiltration device is a compact skid-mounted membrane separation unit designed for low-flow water purification and material separation, often matched with ultrafiltration membrane cleaning equipment and used as auxiliary facilities of water treatment ultrafiltration system. This miniaturized UF device realizes efficient interception of suspended solids, colloids, bacteria and macromolecular organics under low transmembrane pressure. Featuring small footprint and flexible mobility, it is widely adopted in laboratory research, small factory water reuse, rural drinking water upgrading and on-site wastewater sampling tests. Unlike large industrial ultrafiltration equipment, the small ultrafiltration device integrates all core components on one frame, greatly lowering installation difficulty and shortening commissioning cycles for end users.

Product Description

Small ultrafiltration device is a miniaturized complete ultrafiltration system, covering flow rates from 0.1m³/h to 5m³/h. The core component can adopt hollow fiber membrane, flat sheet membrane or tubular ultrafiltration membrane according to working conditions. Equipped with feed pump, membrane module, pressure gauge, flowmeter, backwash pipeline and simple control cabinet, the whole system is pre-assembled on stainless steel frame, realizing plug-and-play operation.

This small ultrafiltration device targets scenarios that cannot deploy large-scale water treatment equipment. It can be used for raw water pretreatment, product liquid clarification, and wastewater recovery testing. Customers can choose manual control or automatic PLC control version. For temporary test projects, the mobile small ultrafiltration device can be transported to different sites conveniently. Combined with dosing devices, the system can effectively alleviate membrane fouling during long-time continuous operation. Many project engineers adopt small ultrafiltration device to carry out pilot experiments, collecting operational data to guide the design of formal industrial ultrafiltration water reuse equipment.

Working Principle

The small ultrafiltration device operates on the basis of pressure-driven cross-flow membrane separation. Under the driving force provided by the feed pump, raw liquid flows along the membrane surface. Water molecules and tiny soluble substances pass through membrane pores to form permeate water, while particles, colloids and macromolecular pollutants are intercepted on the membrane surface to form concentrated liquid.

Continuous cross-flow scouring reduces pollutant accumulation on the membrane surface. When membrane flux drops obviously, the device can start backwashing to wash away surface filter cake. For stubborn organic and inorganic contamination, online chemical cleaning can be conducted. After cleaning and regeneration, membrane flux can recover to most of the initial level. Operators can adjust operating pressure, circulation flow and backwash frequency according to water quality changes. The small ultrafiltration device can run intermittently or continuously, perfectly matching the discontinuous production characteristics of laboratories and small processing workshops.
