Product Overview
Ultrafiltration (UF) is a membrane separation technology driven by pressure, aimed at separating large and small molecules. Under a specified pressure, small‑molecule solutes and the solvent pass through a specially designed membrane with a defined pore size, while larger molecular solutes are retained, thereby achieving purification, separation, or concentration of the solution. Typically, ultrafiltration membranes have pore sizes ranging from 0.03 μm to 1 μm, and operate at pressures of 0.1 to 0.5 MPa, effectively removing particulates, colloids, bacteria, pyrogens, and high‑molecular‑weight organic substances from water. Over the years, as ultrafiltration technology has advanced, its applications have become increasingly widespread.

Application areas
① In the case of potable water, ultrafiltration removes only suspended solids, colloidal particles, and bacteria, while retaining minerals that are beneficial to human health.
② Municipal, domestic, school, catering, hotel, commercial, and rural water use; pre- and post‑treatment of purified water.
③ Seawater desalination, pharmaceutical-grade water, pure water systems for the chemical industry, bioengineering systems, and pure water systems for the food and beverage industry.
④ Reuse of reclaimed water, sewage, and wastewater treatment.
⑤ Oily wastewater, heavy-metal‑contaminated wastewater, textile dyeing and printing wastewater, papermaking wastewater, and municipal domestic sewage treatment.
⑥ Separation and concentration of special solutions.
⑦ Biotechnology for concentration and separation; purification, concentration, and impurity removal in traditional Chinese medicine preparations; starch recovery applications; and concentration and clarification applications in the food and beverage industry.Process Principle
During ultrafiltration, an aqueous solution is driven by pressure across the membrane surface. Solvent (water) and small‑molecule solutes smaller than the membrane pores pass through the membrane to form the permeate (filtrate), while solutes larger than the pores are retained and discharged with the retentate as a concentrated stream. Ultrafiltration operates in two modes: dead‑end filtration and cross‑flow filtration. In dead‑end filtration, all feed water passes through the membrane to produce permeate; in cross‑flow filtration, only a portion of the feed water permeates, while the remainder carries impurities and is discharged as reject water. Dead‑end filtration offers lower energy consumption and higher recovery rates, resulting in reduced operating costs, whereas cross‑flow filtration can handle feed streams with higher suspended solids concentrations. The specific operational mode should be selected based on the suspended solids content of the feed water.
Product Features
- The separation process does not involve phase changes and does not induce variations in temperature or pH, thereby preventing the denaturation, deactivation, and autolysis of biomacromolecules.
- The separation process can be carried out at ambient temperature, with low energy consumption.
- The separation process is driven solely by low pressure, featuring simple equipment and a straightforward process flow, resulting in low costs. It requires no additional chemical reagents and is easy to operate, manage, and maintain.
- It has a wide range of applications: any substance with a molecular weight between 1,000 and 500,000 daltons, or with particle sizes ranging from approximately 0.03 to 0.1 μm, can be separated using ultrafiltration technology.
