    Abstract: A method and system of treatment of agricultural and industrial wastewaters that contain high concentrations of suspended solids, nitrogen, and phosphorus compounds is disclosed. The method and system includes pre-treating the wastewater, controlling the amount of coagulants used, and controlling the mean velocity used for mixing, surface loading rate, and solids loading rate. The method and system functions as a sedimentation unit and gas flotation unit (solid/liquid separator). The pH of the effluent wastewater is stabilized within the separator by ensuring that there is sufficient alkalinity to buffer the wastewater. Sufficient gas is produced in the coagulation reactions to float and concentrate the solids, which results in as high as 99 percent reduction in suspended solids, a 96 percent reduction of the phosphorus concentration, and a 50 percent reduction of the nitrogen concentration in the effluent from the separator.

    Abstract: Disclosed herein is a method for zero-discharge treatment of high-concentration organic wastewater by mixing sludge with high-concentration organic wastewater. The sludge is biodried sludge prepared by a method including preparing a sludge mixture consisting of belt-pressed sludge and dried sludge; and collecting the sludge mixture when its temperature finally becomes stable by returning to room temperature. The high-concentration organic wastewater used contained small particles of pulverized food waste having a diameter of 1 mm or less. The treatment was performed by decomposing the organic materials using microorganisms contained in the sludge via metabolism, followed by water evaporation caused by the metabolic heat generated by the decomposition of the organic materials, in which the microbial metabolism was performed under an aerobic condition.
