Trickling Filter unique feature
CO2 and N2 can be effectively removed from the water, and also can increase the dissolved oxygen in water very well.
Trickling Filter working principle
Waste water flowing through the top of the trickling filter by gravity,during the process CO2 will be discharged from the water, and at the same time increase the dissolved oxygen in the water, then the dissolved oxygen of water will flow through the filter material, has frosted a large number of aerobic bacteria( nitrifying bacteria), the aerobic bacteria converts the metabolites in the water to N2 and discharges it.
