TL;DR: Biological filtration contributed significantly in nutrients removal processes and the obtained effluent was low in carbon and rich in nitrogen, which can be applied for restricted irrigation after disinfection, complying with the discharge limits set in the Greek Joint Ministerial Decree 145116/2011.
Abstract: The main objective of wastewater treatment is to remove carbon and other nutrients from municipal and industrial effluents in order to protect the environment and human health. Typical wastewater t...

TL;DR: In this paper, a method and apparatus for treating sewage or other waste material by subjecting it to the mechanical and biological actions of a trickling filter is described. But this method is not suitable for the treatment of agricultural waste.
Abstract: Our invention relates generally to filtration treatment of sewage or other waste material, and it has to do particularly with a method and apparatus for treating such material by subjecting it to the mechanical and biological actions of a trickling filter. It is to be understood that the term...

TL;DR: A review of research carried out to study various aspects of trickling filter system with respect to its efficiency, operating parameters, economy of the process are presented in this paper, it was observed that the trickling system has been used very effectively in laboratory scale.
Abstract: Waste water treatment by using biological methods is very important area of research in environmental field because of its advantages and applicability. The suspended growth processes like activated sludge process are common in treatment facilities. Various aspects of biological processes for removal of various pollutants are being studied by investigators. The current review aims at studying the trickling filter systems for removal of various pollutants. The review of research carried out to study various aspects of trickling filter system with respect to its efficiency, operating parameters, economy of the process are presented in this paper. It was observed that the trickling system has been used very effectively in laboratory scale. In many investigations, pilot plant and further scale up was also done successfully. Trickling filter system with or without some modifications have been used successfully for removal of organic and inorganic matter, pathogens.

TL;DR: In this article, a wastewater treatment system is described where trickling filters remove a high proportion of biochemical oxygen demand, total suspended solids (60), and nutrients from wastewater (24) using, in one embodiment, a pressurized media container (14).
Abstract: A wastewater treatment system (10) is disclosed whereby trickling filters remove a high proportion of biochemical oxygen demand, total suspended solids (60), and nutrients from wastewater (24) using, in one embodiment, a pressurized media container (14). The system (10) accomplishes this in an improved way by combining venturies (28) or blowers to aerate the wastewater (24), and recirculating the wastewater (24) and air (26) down through the treatment media (52), improving the overall efficiency of the system (10) and reducing its size. A screen (46) at the base of the pressurized media container (14) supports the media (52) and allows the wastewater (24) to exit the pressurized media container (14). The system (10) also includes a low pressure nozzle (42) that aids in the proper distribution of the wastewater (24).
