Ultrafiltration Membrane System Pvdf for Industrial Swege Water Solution

UF is a separation process using sieving as the separation principle, which uses pressure as the driving force to achieve mechanical separation. When the mixed solution containing different sizes of the molecular solute flows through the membrane surface, the solvent and small molecules such as inorganic salts pass through the membrane and teh macromolecule solute is trapped to achieve the purpose of separation and purification.
With over 20 years of separation-technology leadership and products in more than 500 ultrafiltration installations worldwide, we offer a portfolio of products designed for outstanding membrane separation, extreme productivity and efficiency, and exceptional reliability.

Brief Introduction of UF Membrane

Ultrafiltration is one membrane filtration process that serves as a barrier to separate harmful bacteria, viruses, and other contaminants from clean water. An ultrafiltration water system forces water through a .02 micron membrane. Suspended particles that are too large to pass through the membrane stick to the outer membrane surface. Only fresh water and dissolved minerals pass through.

At present, the commonly used ultrafiltration membranes in industrial production are: plate and frame type, circular tube type, spiral wound type, hollow fiber type, and capillary type. Various industries must choose different types of ultrafiltration membranes according to their needs to give full play to their performance.

The development of membrane technology has brought great convenience to the treatment of production water and the concentration and separation of substances in various industries. With the continuous advancement of science and technology, ultrafiltration membrane technology has been continuously improved, occupying a leading position in the market with its unique properties.


Use, Cleaning and maintenance of membrane module

The UF membrane module must be used in the regulated pressure , temperature and pH, The turbidity of the water entering the UF membrane is less than 50NTU, the particle size of the water entering the ultrafiltration membrane is 50-100 μm,and the SDI of the water produced by the UF  membrane module is less than or equal to 0.2 NTU, and its SS is less than 0.2. The rejection rate of UF membrane on microbial,bacterial, E. coli, pathogen is more than 99.99%. The membrane surface of UF membrane in the course of application is easy to pollute, resulting in membrane water production decline. UF membrane module should be cleaned regularly in a timely manner by physical and chemical cleaning methods.

Substances of different molecular weights can be fractionated.

During the operation of the ultrafiltration membrane, no impurities will fall off, ensuring the purity of the ultrafiltrate.

The ultrafiltration membrane has the characteristics of selective separation, which can retain the mineral elements that are beneficial to the human body.

The equipment is compact in structure, small in floor space and easy to operate.

It has strong applicability to water quality and has a wide range of applications.


Applications

Electronics industry: semiconductor industry ultrapure water equipment, integrated circuit cleaning water treatment equipment;

Pharmaceutical industry: medical pure water, drug concentration and separation;

Water treatment project: pure water preparation, drinking water purification, reverse osmosis device.

Food industry: juice concentration and clarification, protein concentration and separation.

Wastewater treatment project: industrial wastewater, municipal wastewater treatment and reuse, etc.


  • Wastewater treatment: With the increasing importance of environmental pollution control, industrial wastewater and urban sewage treatment have been further developed to advanced treatment, and reclaimed water projects have been put on the agenda. Ultrafiltration deep purification and utilization of membrane bioreactors combined with biotechnology and ultrafiltration technology have begun to be applied in urban sewage and industrial wastewater treatment. A new starting point for the development of ultrafiltration technology in my country will be the industrial application of wastewater treatment. Compared with the industrial application of water purification, wastewater treatment is more difficult and lacks practical experience. Therefore, a lot of work needs to be done in the development of membrane module production and application technology. At present, the fouling-resistant coarse capillary ultrafiltration membrane has achieved good results in preliminary application.

  • Application of purification function:

    a. Water industry

    ①Pretreatment of reverse osmosis in the preparation of ultrapure water and pure water. The SDI of pretreated water quality can reach 0~1;
