Industrial Ultrafiltration Water Purification Equipment;

Ultrafiltration (UF) is a separation technology that uses a certain pressure for separation, which is a separation of ultra-fine particles and macromolecules.
An effective method of matter, which is characterized by high efficiency, low cost and easy operation

The principle of ultrafiltration

Ultrafiltration is a dynamic separation process that allows some components to pass through while preventing some others from passing through. The separation effect comes from the screening effect of the ultrafiltration membrane. Ultrafiltration membranes act like filters, they divide substances into different parts by force, with the aim of separating out the substances that are needed. The screening of ultrafiltration membranes is based on several factors, such as membrane pore size, membrane permeability, membrane thickness, and physicochemical properties of the membrane.

The pore size of an ultrafiltration membrane is a key factor in determining its screening effect. Ultrafiltration membranes with smaller pore sizes are able to filter out smaller substances while passing through larger ones. Pressure is an essential factor in the ultrafiltration process, which is used to facilitate the transition of molecules or ions from one side of the membrane to the other. Due to the pressure ratio of the filtrate

The liquid pressure on the membrane is high, so the substance is able to penetrate from the filtrate onto the membrane. As the pressure increases, the permeability of the substance also increases, but the strength of the membrane is also affected, so the service life of the membrane is also limited.

Ultrafiltration control factors

Ultrafiltration is a complex process, and many factors can affect its performance. In order to achieve good ultrafiltration results, it is necessary to get right
Different control factors are finely adjusted and managed. The factors that lead to poor ultrafiltration include the following.

○ Filtrate flow rate
Filtrate flow rate refers to the rate at which the filtrate passes through the ultrafiltration membrane. In general, the lower the filtrate flow rate, the less adhesion and erosion there is to the membrane. However, if the filtrate flows
If the speed is too slow, the filter cake may be bound to the surface of the filter membrane, thus limiting the mass transfer and degrading
Low ultrafiltration efficiency. Therefore, it is necessary to find a suitable filtrate flow rate.

○ Operating pressure
Ultrafiltration operating pressure is a very critical control factor. Typically, ultrafiltration operates at a pressure of 3-6 Bar, with slightly different operating pressures for different membranes. If
If the working pressure is too high, it will reduce the life of the membrane, and at the same time cause permanent deformation and performance degradation of the membrane.
If the operating pressure is too low, filtration can be reduced, resulting in process waste and products that do not meet the required quality standards.

○ Thickness of ultrafiltration membrane
The thickness of the ultrafiltration membrane also has an impact on the ultrafiltration effect. When the ultrafiltration membrane is thinner, the separation of macromolecular substances is better, and the life of the membrane is also extended. but
Yes, if the film is too thin, it may cause the strength of the film to decrease, which will affect the reliability of the film
and durability, so it is necessary to select the right materials and processes to manufacture ultrafiltration membranes.

○ Temperature and pH Temperature and pH are also important factors that affect ultrafiltration performance. Within a certain range, the higher the temperature, the more active the thermal movement of the molecules, thus promoting the movement of the molecules in the ultra
Movement on the membrane. However, excessive temperatures can damage the membrane material and reduce the life of the ultrafiltration membrane. In addition, pH can affect the ionic strength and strength of the ultrafiltration media
molecular size, so the pH needs to be carefully handled in the process to meet ultrafiltration conditions.
Ultrafiltration is a highly efficient technology for all types of particles, which can effectively separate some mechanical and smaller particles and substances. Despite its very wide range of applications,However, it is very important to avoid ultrafiltration failures and jams, so the principles and factors of ultrafiltration need to be carefully considered to ensure that the desired ultrafiltration effect is obtained.

Features of ultrafiltration equipment

○ The filtration effect is stable
The water quality of the ultrafiltration equipment is not affected by the fluctuation of raw water quality, which can ensure the stability and consistency of the water quality of the produced water.

○ Low energy consumption
Running at room temperature and pressure, the operating cost of the ultrafiltration system to treat surface water is only 0.28 yuan

○ High efficiency
The utilization rate of the original solution is high, the waste is small, and the recovery rate of the tap water treated by the ultrafiltration system is as high as 95%.

○ No phase change
The ultrafiltration separation process belongs to pure physical separation at room temperature, and there is no need to worry about the change of the properties of the substances after ultrafiltration separation. And there will be no secondary residue.

○ Wide range of separation
Ultrafiltration membranes can be made into products with different filtration ratings from 2 nm to 100 nm for different applications.

○ Easy to expand
The filter system is easy to install, and when the throughput needs to be expanded, only the membrane host needs to be increased by the corresponding throughput.
