Sedimentation tanks called " secondary clarifiers " remove flocs of biological growth created in some methods of secondary treatment including activated sludge, trickling filters and rotating biological contactors.

Some of the latest trickle filter technology involves aerated biofilters of plastic media in vessels using blowers to inject air at the bottom of the vessels, with either downflow or upflow of the wastewater.

This resulted in his utilisation of the " trickling filter " system to treat septic tank waste on site, in response to his concern that septic tanks were being pumped out untreated into the environment.

The treated water effluent from industrial wastewater trickling filters is typically processed in a clarifier to remove the sludge that sloughs off the microbial slime layer attached to the trickling filter media as for other trickling filter applications.

In older plants and those receiving variable loadings, trickling filter beds are used where the settled sewage liquor is spread onto the surface of a bed made up of coke ( carbonized coal ), limestone chips or specially fabricated plastic media.

Both the investments costs and the energy consumption of the trickling filter plant are extremely low, for which the Austrian engineering company working on the plant was honored with an innovation award by the International Water Association ( IWA ), a professional association.
19.
The current system ( detailed in ) consists of an " S3 Environmental Solutions Ltd " nitrification tower ( a trickling filter also known as an aeration or biofilm tower ) through which the leachate is circulated over a biofilm supported on a plastic media.
20.
Systems can be configured for single-pass use where the treated water is applied to the trickling filter once before being disposed of, or for multi-pass use where a portion of the treated water is cycled back and re-treated via a closed loop.
