TLDR
In this article, the authors describe a treatment plant for wastewater, where a shared housing 2, a chamber 3 for a trickling filter 4, a final clarification tank 10 and a pump chamber 5, separated from these by a wall 15.Abstract:
In a treatment plant for wastewater, there are provided, in a shared housing 2, a chamber 3 for a trickling filter 4, a final clarification tank 10 and, separated from these by a wall 15, a pump chamber 5. In the final clarification tank 10 which is disposed immediately under the chamber 3 for the trickling filter 4, there is provided a pump 25 from which there departs a line 26 which leads to a digestion chamber which is connected upstream of the trickling filter 4. From the final clarification tank 10 wastewater flows through an overflow 17 in the wall 15 into the pump chamber 5. In the pump chamber 5 there is provided a pump 28 from which a line 29 departs which leads to a soil filter chamber. In this line 29 is provided a three-way valve 30 from which a pipe branch 31 departs which ends above the trickling filter 4.read more

Liq. purificn. in contact beds - with direct introduction of oxygen for microorganism growth
TL;DR: The direct application of O2 to the microorganisms improves their physiological performance and raises the efficiency considerably, even when used for sewage which is otherwise difficult to clean as mentioned in this paper, and the O2 flow rate, temp. moisture and pressure are controlled for optimum growth conditions.

Trickling filter for sewage clarification - adding oxygen to circulating air and discharging min. of waste air
TL;DR: In this article, the discharge of air from a trickling filter bed is adjusted by a control unit automatically adjusting the discharge and the oxygen addn. This keeps the amt. of air discharged to the environment and thereby the bad odours to a min.

Process for biological purification of waste water by trickling over bacterial beds and device employed.
TL;DR: In this paper, a process for biological purification of waste water is described, where the packing material becomes too blocked and is replaced by a cleaning solution containing at least 7 g/l of ammonium ions and preferably a solution of aqueous ammonia and ammonium chloride taken from the vessel.
