How to choose the liquid filter bag
First, we need to understand the filtration mechanism of the bag filter system: the liquid flows from inside the bag to outside the bag, and the particles are trapped inside the bag. The bag filter works by pressure filtration. The bag filter system mainly consists of three parts: filter container, support basket and filter bag.
Net cloth filter bag material choice: first of all, according to the chemical name to filter the fluid, according to the filter material of chemistry with taboo to find available, then aiming at the filter medium temperature, operating pressure, ph, viscosity (CPS), types of impurities such as (hard particles, soft particles), impurity content (PPM), operating conditions (such as whether to need to tolerate steam, hot water or chemical sterilization, etc.), assessed, and eliminate shall not apply to the filter material. Use is also an important consideration. Filters for drugs, food or cosmetics, for example, must be fda-approved; For ultrapure water, filter materials that are pure and do not contain release materials that affect specific impedance should be selected. Filter gas must be selected hydrophobic material and whether the need for "sanitary filtration" design, and so on
