biological filter

The biological filter is the use of beneficial natural bacteria to get rid of organic waste compounds from the water, a process through which the ammonia compounds in the water are oxidized to nitrite and then to nitrate. The bacteria that work in the biological filter are part of the "nitrogen cycle", which is a series of events that operate in nature.

It can combine the advantages of aeration filter and solid waste removal to improve the formation of highly concentrated biological film with high processing efficiency, the conversion rate of ammonia nitrogen can be improved 2-4 times, it has the double function of biological filter and novice mechanical filter, and at the same time it has the functions of backwashing.
