Nowadays, the activated sludge process is utilized greater than the trickling filter. In this process, the air and sludge are allowed to come in close contact with the microbes. Soon after this, it can be allowed to go through the settling tank.

Investment decision in wastewater treatment systems is shifting from new construction jobs to maintenance of primary capability and function of services (asset management).

A trickling filter is actually a tank crammed with a deep bed of stones. Settled sewage is sprayed continuously over the top in the stones and trickles to the bottom, the place it can be collected for even further treatment.
