    WASTE FILTERING APPARATUS
    TECHNICAL FIELD OF THE INVENTION
    The invention disclosed herein generally relates to waste filtering apparatus implemented in a sewage treatment plant. More particularly, the invention disclosed herein relates to a waste filtering apparatus for sorting out waste before entry into the sewage treatment plant.
    BACKGROUND
    Residential, institutional, commercial and industrial establishments generates sewage. It includes household waste, liquid from toilets, baths, showers, kitchens, and sinks draining into sewers. In many areas, sewage also includes liquid waste from industry and commerce. Today, environment possess a major problem on handling large quantities of waste or debris in sewers of the sewage treatment plant, especially in the event of heavy rain. Waste may include cigarettes, ice sticks, glasscutters, leaves, branches, paper capsules, pens, etc.
    The separation of the solid and liquid waste prior to sewage treatment plant is very a crucial step. The solid waste could be accumulated into a system used for wastewater management. Once accumulated the solid waste may block the flow of liquid, and hinder the processing steps involved in the wastewater management system. The solid waste could even damage the system, causing blockage into the waste management system. The damage of the system could delay the wastewater treatment process. Further, the repairing of the system could be too expensive and cumbersome.
    The waste material to be treated contains a very high biochemical oxygen demand (BOD) and/or very high chemical oxygen demand (COD). The deposition of the effluent having high BOD and COD into the lakes lagoons or rivers results in lowering the concentration of dissolved oxygen. This may produce septic conditions accompanied by foul odors,
    DK 2017 00628 A1 death of natural fauna, and a buildup of scum on the surface of the water. Oxidation of these materials using oxidizing agents is not feasible, since the expense of oxidizing agents is very high.
    Henceforth, it is desirable to provide an apparatus for sorting the solid and liquid waste prior to subjecting into the sewage treatment plant or depositing in the water bodies.
