Ultrafiltration Reverse Osmosis Equipment - Stable Performance, Wine Filtration Equipment - Quankun

Ultrafiltration membranes are categorized into various structural types, including plate-and-frame (plate type), hollow fiber, nanofiltration, tubular, and rolled structures. Among them, hollow fiber ultrafiltration membranes are a mature and advanced form of ultrafiltration technology. The outer diameter of hollow fiber ranges from 0.4 to 2.0mm, and the inner diameter from 0.3 to 1.4mm. The walls of the hollow fiber tubes are lined with micropores, with pore sizes expressed by the molecular weight of the substances they can retain, reaching up to several thousand or even tens of thousands. Raw water flows at high pressure on the outer side or inner cavity of the hollow fiber, forming external pressure and internal pressure hollow ultrafiltration membranes, respectively. The ultrafiltration system is a dynamic filtration process; retained substances can be removed with the concentrate, preventing blockage of the membrane surface, allowing for long-term continuous operation.

Principle of Ultrafiltration Equipment:

Ultrafiltration is a membrane separation process driven by pressure, utilizing sieving as its separation principle. It offers a filtration precision ranging from 0.005 to 0.1 μm, effectively removing particles, colloids, bacteria, heat sources, and high-molecular organic substances from water. It is widely applicable in the separation, concentration, and purification of substances. The ultrafiltration process involves no phase change and operates at room temperature, making it particularly suitable for separating heat-sensitive materials. It also boasts excellent temperature resistance, acid and alkali resistance, and oxidation resistance, allowing for long-term continuous use under conditions of 60°C or below and a pH range of 2 to 11.

Ultrafiltration membrane classification:

Ultrafiltration membranes are categorized into various structural types, including hollow fiber, plate-and-frame (plate), nanofiltration ultrafiltration, tubular, and rolled configurations. Among them, hollow fiber ultrafiltration membranes represent a form of ultrafiltration technology. These hollow fibers have an outer diameter of 0.4-2.0mm and an inner diameter of 0.3-1.4mm, with their tube walls densely packed with micropores. The pore size is expressed in terms of the molecular weight of the substances retained, with retention molecular weights ranging from a few thousand to tens of thousands. Raw water flows under pressure on the outer side or inner cavity of the hollow fibers, forming either external pressure or internal pressure hollow ultrafiltration membranes. Ultrafiltration is a dynamic filtration process; retained substances can be removed with the concentrate, preventing clogging of the membrane surface, allowing for long-term continuous operation.

Key Features of Ultrafiltration Membrane Equipment:

1. The system employs high-pollution-resistant hollow fiber column membrane modules, which are easy to clean and maintain stable water output with minimal contamination.

2. The system employs a unique online air-water dual-washing technology, ensuring stable water output and excellent cleaning flux.

3. The system can be modularly designed, featuring a compact structure, small footprint, and ease of assembly for use.

4. PLC control is employed, offering a high degree of system automation and easy operation management.
