Large ultrafiltration equipment

Product Overview

Large Ultrafiltration Equipment is designed for high-flow and continuous water treatment applications, capable of handling large volumes of raw water with stable and reliable performance.
The system uses advanced ultrafiltration (UF) membrane technology to effectively remove suspended solids, colloids, bacteria, algae, and macromolecular organic matter, making it an ideal solution for municipal, industrial, and large-scale pretreatment projects.

It is commonly used as pretreatment for RO and seawater desalination systems, as well as for water reuse and industrial process water purification.

Working Principle

Large ultrafiltration systems operate on a pressure-driven membrane separation process:

  • Raw water flows through UF membrane modules under low pressure

  • Particles larger than the membrane pore size are retained

  • Clean water passes through the membrane as permeate

  • Concentrated impurities are discharged through automatic backwash and drainage

UF membranes typically feature a pore size of 0.01–0.1 μm, ensuring stable turbidity and SDI control.

Key Features & Advantages

  • Large treatment capacity, suitable for continuous operation

  • Excellent turbidity and SDI control

  • High bacteria and colloid removal efficiency

  • Automatic backwash & air scouring system

  • Low operating pressure and energy consumption

  • Modular skid design for easy expansion

  • Long membrane service life

Applications of Ultrafiltration Technology

In the early days, industrial ultrafiltration was used for wastewater and sewage treatment. Over the past three years, with the development of ultrafiltration technology, ultrafiltration membrane technology has now been applied in a wide range of fields, including the food industry, beverage industry, dairy industry, biofermentation, biopharmaceuticals, pharmaceutical chemicals, biological preparations, traditional Chinese medicine preparations, clinical medicine, printing and dyeing wastewater, food industry wastewater treatment, resource recovery, and environmental engineering.
