Filtering principle of capsule bag filter

The capsule bag filter is mainly used in the fields of medicine, chemical industry, electronics, bioengineering, cosmetics, food and beverage. It can also be called the capsule bag filter element, without du. So, how much do you know about the filtering principle of capsule bag filter.

Next, the editor of State Filter Environmental Protection will focus on this aspect to deepen our understanding of it. Let's have a look.

First of all, we need to know that the filter media used by capsule bag filters with different characteristics are also different. Common ones are RFPT, which uses hydrophobic polytetrafluoroethylene (PTFE) filter membrane, which is suitable for solvent and corrosive solution filtration, and air and gas vent filtration. In addition, the RFPP bag filter uses hydrophilic polypropylene (PP) membrane, which is suitable for pre-filter of reverse osmosis and ultrafiltration, ink filtration, etc. Suitable for filtering aqueous solutions and solvent samples. The RFPN bag filter uses nylon membrane, which is characterized by fast flow rate and low extractable level. The pre-filtration medium containing glass fiber can be selected, which can prolong the service life of nylon membrane, and is suitable for the filtration treatment of large volume samples and hard filtration samples.

Product features:

Du can be eliminated by steam or ETO pressurization heating;

Hydrophobic polypropylene film and polypropylene shell are corrosion resistant;

Durable low pressure differential, high flow flux, and long service life of bag filter;

Wide applicability.

In addition, the product has various shapes and sizes of interfaces (thread, hose, pagoda, buckle, etc.), which can meet various conversion joints; And filtration membrane. It adopts a unique cascade structure and applies the working principle of circular flow channel. Compared with conventional filters, its residual volume and particle shedding are lower. Connect the hose to the inlet and outlet respectively, open the exhaust port at the top, pay attention to the fluid direction, and pass in the filtrate. When the filtrate is full of the filter and all the air is squeezed out, tighten the exhaust port of the bag filter. When the filtering process results, open the exhaust port at the bottom of the filter to discharge the remaining filtrate.
