Mechanical filtration:

When the water flows through the filter tank, large particles will be trapped by the filter media, small particles will be also blocked by the linked filter media. After certain time, these particles will be accumulated and the pressure inside the tank will increase, then the filter can be backwashed to clear the accumulated particles and release the tank pressure.


Biological filtration:

By breeding beneficial bacteria inside the filtration media in the filter tank, the beneficial bacteria can convert into non-toxic substance and digested.
