The technology involves a grit chamber to separate inert material, followed by a thickening tank and stabilization of sludge in a stabilization reactor. The discharge then enters a screw press and in the presence of flocculent, solids are separated from wastewater. Solids are then transferred to the sludge drying beds, where residual water is collected at the bottom of the bed. The percolated water is then mixed with the main stream of wastewater from the screw press in the equalization tank and the water is further treated using integrated settler and ABR, anaerobic filters. After which filtered in planted gravel filter, activated carbon filter and, finally, UV treatment. The treated water is currently being used in horticulture purposes within FSTP premises. |
