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: A substrate treatment unit applies surface treatment to a semiconductor substrate by using a chemical solution. The chemical solution in which metal is dissolved by substrate treatment is discharged into a storage tank and stored. A polyacid supplying unit supplies polyacid of a deletion complex with a deficient portion into the storage tank. The polyacid of deletion complex with a deficient portion is mixed into a used chemical solution containing the metal, and a pH value of the mixed solution is adjusted to between 2 and 3 to capture the metal dissolved in the chemical solution in the deficient portion of the polyacid. In addition, a counter cation is put into the chemical solution so that the polyacid in which the metal is captured is precipitated to be separated from the chemical solution, and thus the metal contained in the chemical solution during the treatment of the semiconductor substrate can be removed to enable the chemical solution to be reclaimed.
