Methods of recovering nutrients from a high nitrogenous liquid waste are disclosed. The methods include collecting the high nitrogenous liquid waste, introducing the high nitrogenous liquid waste and an oxidant into a reactor to produce oxy-anions of nitrogen, maintaining a predetermined pH to control concentration of the oxy-anions of nitrogen, and concentrating the liquid to produce a concentrated product and a dilute water. Systems for recovering nutrients from a high nitrogenous waste are also disclosed. The systems include a solids-liquid separator, a reactor having an inlet fluidly connected to the solids-liquid separator and an inlet fluidly connected to a source of an oxidant, a pH control subsystem, and a dissolved solids concentrator.

A waste treatment system 100 for performing a hydrothermal treatment of wastes includes a hydrothermal treatment device 10 for performing the hydrothermal treatment by bringing steam into contact with the wastes, a storage facility 8, 9 for storing a fuel produced from a reactant of the hydrothermal treatment, and a heat recovery steam generator 18 for generating the steam to be supplied to the hydrothermal treatment device 10. The heat recovery steam generator 18 is configured to generate the steam by using a combustion energy generated by combustion of the fuel stored in the storage facility 8, 9.

An ammonia capture and recovery system comprises five process steps, including an ammonia removal step, an ammonia recovery step, a product granulation step, a granulated product wax-coating step, and a granulated product encapsulation step. These steps are modular in that multiple approaches are valid for each step if it meets the process requirements for the next influent. Also, a method of taking ammonia-containing wastewater and producing several water fractions (preferably of decreasing volume and increasing purity) and a time-release ammonium-containing fertilizer, resulting in a sustainable nitrogenous fertilizer product that reduces fertilizer use and subsequent nutrient runoff while being produced from wastewater and not fossil fuel or hydrogen sources.

The present disclosure discloses a preparation method for hyperthermophilic aerobic fermentation inoculant prepared by using sewage sludge, the method includes the following steps: carrying out fermentation after the activation of hyperthermophilic aerobic bacteria, removing the supernatant from the fermentation products, and adding the protective agent and stirring until uniform, drying to obtain a product, pulverizing the product by a pulverizer, and sieving the product before sub-packing. The solution of the present disclosure has the following advantages.

The invention provides an efficient system for treating livestock waste, particularly waste from cattle or pig farming. The new facility and method employ special transfers of slurry streams through ASBR, SBR, and a unique pretreatment reactor, resulting in treated water, quality compost, and biogas.

A method for purification of water with a water purifier. The water purifier includes an anode and a cathode as electrodes in such a way that a gap remains between the anode and the cathode. In the method, an electric field is generated between the anode and the cathode, water for purification is conveyed to the gap and an additive enhancing floc formation is introduced to water for purification or to purified water in an amount of less than 50 g and at least 1 g, measured as dry matter, per each cubic metre of water for purification. Floc material manufactured with the method, when water for purification is municipal wastewater. The use of the floc material produced in this way as a soil conditioner or for manufacturing a soil conditioner.
