The difference between the cartridge filter:

If the filter element filter is used in front of reverse osmosis, it is usually called a security filter. The security filter is to ensure the safety of the water entering the membrane. The general precision is 5 microns. Later, the cartridge filter is also called a microporous membrane filter. At this time, the filter accuracy is usually below 1 micron, mainly to remove impurities from bacteria in the water after passing through the ultraviolet sterilizer. The filter element of the filter element filter has a wire-wound filter element, a pleated filter element and a melt-blown filter element. Since the melt-blown filter element is cheap, the melt-blown filter element is used most in water treatment. The filter element is blocked and replaced directly, and the cost is small.

The difference of bag filter:

The bag filter is a multi-purpose filtration equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight work and strong applicability, and a new type of filtration system. The filter bag is supported by a metal mesh basket inside, the liquid flows in from the inlet, and flows out from the outlet after being filtered by the filter bag.

Compact structure and reasonable size. Simple and convenient installation and operation, small footprint, high filtration accuracy, suitable for any fine particles or suspended solids, the filtration range can be from 0.5 to 200 microns, the processing flow per unit filtration area is large, the filtration resistance is small, and the filtration efficient. The filtering function of a liquid filter bag is equivalent to 5-10 times of the filter element, which can greatly reduce the cost; the designed flow rate can meet the requirements of 1-500m3/h, and the cost is low.
