The 5T/h hollow fiber ultrafiltration device combined with well-designed filtration and adsorption can effectively remove various bacteria, viruses and pesticide residues in the water. Because the hollow fiber ultrafiltration membrane is only used for filtration, it can not filter the trace elements in water. (such as calcium, magnesium, etc.). So it can only be a kind of precision filtration of the front end of the RO membrane. When using, strictly follow the instructions for operation, maintenance and maintenance.

Ultrafiltration membrane filtration principle:

Hollow fiber ultrafiltration is a screening process related to the pore size of the membrane. The pressure difference between the two sides of the membrane is used as the driving force. The ultrafiltration membrane is used as the filter medium. Under a certain pressure, when the raw liquid flows through the membrane surface. Many fine micropores densely coated on the surface of the ultrafiltration membrane allow only water and small molecules to pass through to become permeate. And substances in the original solution having a volume larger than the micropore of the membrane surface are trapped on the liquid inlet side of the membrane to become a concentrate. Thus, the purpose of purifying, separating and concentrating the raw liquid is achieved.

The stock solution generally refers to a solution that needs to be purified, separated or concentrated. The permeate refers to the part of the liquid in which the macromolecular solute is filtered out through the ultrafiltration membrane. And the concentrate is the remaining in the stock solution due to the separation of the permeate. High concentration solution. In the purified water project, the raw liquid means that the raw water enters the water. The permeate is the purified water, and the concentrated liquid is the discharged waste water.

A hollow fiber ultrafiltration membrane device is mainly composed of hundreds to thousands of small hollow fiber filaments and a membrane shell. The ultrafiltration membrane with an inner diameter of the hollow fiber membrane of 0.6-6 mm is generally called capillary ultrafiltration. Membrane and capillary ultrafiltration membranes are not easily blocked by large particulate matter due to their large internal diameter, and are more suitable for applications where the concentration of the filtrate is large.

The separation process of the ultrafiltration membrane has the following salient features:

1. Separation at normal temperature and low pressure, resulting in low energy consumption, resulting in low operating costs of the equipment.
The 2.5T/h hollow fiber ultrafiltration device has a small volume and a simple structure, so the investment cost is low.
3. The ultrafiltration separation process is simply a pressurized delivery of liquid, the process is simple, and easy to operate and manage.
4. Ultrafiltration membrane is a uniform continuum made of polymer material. It is filtered by pure physical method. The substance does not undergo qualitative change during the separation process, and no impurities will fall off during use to ensure the ultrafiltrate. Pure.
