Its advantages are a large amount of filtered water, high pollutant removal capacity, and long operating cycle, usually 20 hours. The disadvantage is that the pipeline system is complex, the operation is not very stable, and it is difficult to flush and replace materials.

2： Working principle of tank type mechanical filter: The mechanical filter uses one or several filtering media to pass the original liquid through the media under a certain pressure, removing impurities and achieving the purpose of filtration. The fillers inside are generally quartz sand, anthracite, granular porous ceramics, manganese sand, etc. Users can choose to use them according to their actual situation. Mechanical filters are one of the traditional water treatment methods that mainly use fillers to reduce turbidity in water, intercept suspended solids, organic matter, colloidal particles, microorganisms, chlorine odors, and some heavy metal ions in the water, and purify the water supply.
