How to select pleated filter cartridge, membrane pleated filter cartridge and micro-porous membrane pleated filter cartridge?
To select correct pleated filter cartridge, membrane pleated filter cartridge and micro-porous membrane pleated filter cartridge, you shall consider following 5 factors:
1. Filter media characteristics
First, figure out if it's to liquid or gas. And according to the characteristics of liquid or gas to select of membrane materials or sealing materials, filtration of aqueous solution generally is using hydrophilic membrane, filtering organic solvent can choose hydrophobic membrane, filtering air is using hydrophobic membrane.
2. Filter flow
According to the flux provided by the production process to consider the filter size, the number of filter elements. Generally speaking, the flow rate of the filter element (10 inches) is 0.5 ton/hour (the flux of filtered water), for example, to achieve 1.0 t of flux, you can choose a filter element of 30 inches, leaving some allowance in the right amount, because as the filtration goes on, impurities build up on the surface of the filter and cause a drop in flux. If you use a 20-inch filter, you may not meet the requirement.
3. Pressure, temperature
According to the filter temperature, pressure, disinfection conditions to determine the appropriate filter cartridge. The maximum operating temperature of general filter element is 80 ~ 90 °C. Activated Carbon Fiber is 65 °C, stainless steel pleated filter is 200 °C, titanium sintered filter cartridge is 280 °C, maximum pressure is 0.42 mpa/forward, titanium sintered filter is 0.5 MPA, stainless steel pleated filter cartridge is 0.6 MPA.
4. Filtering requirements
The degree or precision to which filtration is required (requirements for sterilization and degranulation). The filtration efficiency of deep membrane filtration and absolute membrane filtration is different, for example, the absolute precision is 0.2µm for removing bacteria and 10-20µm for removing visible particles.
5. Levels of filtration
The pre-filter is selected according to the contamination degree and impurity content of filtrate, and the purpose of pre-filter is to prolong the life of terminal filter and reduce the cost. The design of pre-filter influences the effect and life of terminal filter.
