Abstract: Incineration is waste destruction in a furnace by controlled burning at high temperatures. Waste incinerators are commonly viewed as harmful to the environment because of the pollutants they inevitably emit. Air filtering is one viable way to minimize the harmful gases produced by incineration. Electrostatic high voltage air filter with water filtration is a highly efficient filtration device that is extremely effective oxidant, lethal to all bacteria and viruses. An electrostatic high voltage air filter is suitable in treating the smoke from the incinerator since it can effectively reduce the pollutants present in the smoke. The water filtration is a viable addition in the filtering system since it reduces the smoke coming from the incinerator. The electrostatic high voltage air filter is placed before the water filtration since the former is sensitive in humid air. The incinerator and the filtering system are separated to protect the filtering components from high temperature coming from the incinerator. MQ135 air quality sensor is used to measure the overall quality of air coming out of the exhaust after the filtering system. Industrial-grade suction fans are used to force the smoke from the incinerator to the filtering system. MCU is used to centralize the operation and control of the incineration and filtration. An LCD is used to monitor the current process and display the real-time data indicated by air quality sensor. A keypad is used to provide selection in the process of incineration and filtration. Three trials in each type of non-recyclable garbage (plastics, papers, dry leaves, and assorted) were conducted to determine the average result in four different conditions (both filters are off, filters are on, only electrostatic filter is on, and only water filtration is on). The evaluation of the performance of the filtering system was observed and therefore concluded that it is capable to reduce the pollutants emitted by the incinerator significantly.
