Treatment disposal of human excreta can be categorized into three types: fertilizer use, discharge and biogas use. Discharge is the disposal of human excreta to soil, septic tank or water body. [75] In China, with the impact of the long tradition, human excreta is often used as fertilizer for crops. [76]
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
Fertigation using white poly bag Fertilizer mixed with water connected to a drip irrigation system. Fertigation is the injection of fertilizers, used for soil amendments, water amendments and other water-soluble products into an irrigation system. Chemigation, the injection of chemicals into an irrigation system, is related to fertigation.
The universities at Iowa State and Wichita State are partnering with a $4 million grant to create a emission-reducing fertilizer. ISU researchers developing green fertilizer system to reuse wastes ...
The Milwaukee Metropolitan Sewerage District's Jones Island Plant had the largest wastewater treatment capacity of any in the world when constructed in 1925. [12] It was the first plant in the United States to succeed in using the activated sludge treatment process to produce fertilizer.
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

The theory does not limit the size of the system, or the amount of species. One design optimum is a natural ecosystem which is designed for a special purpose like a sewage treating wetland in a suitable ecosystem for the locality. Another optimum is an economically viable system returning profit for the investor.
