Title : “Sewage Odor Control In Wastewater Treatment Plant Inlets”
Faculty : Faculty of Engineering, Ain Shams University.
Speciality : Public Works, Sanitary Engineering.
Summary :
The study target was to apply a new concept for odor control concentrates on the use of the air temperature and heat transfer of the gases to remove the bad smell odorous gases specially H2S gas at the entrance of the sewage treatment plant. A new design had been applied using solar chimney conical shape erected above the inlet manhole to increase the gases suction that may be dispersed in the higher layer of the air increasing the area of its dispersion that diluted its concentration in the surrounding air to the permissible limit or treated by activated carbon at chimney top that adsorb it and remove from air that achieved air with only traces of H2S gas in it.
The experimental field work was held on the headwork building in El Reeka wastewater treatment plant in Kuwait during the study period. The solar chimney had been applied with three different sizes for the outlet top to obtain the optimal sizing for the chimney related to the inlet diameter and its height. The experimental work made without activated carbon application in first round then the activated carbon applied in the second run.
The study had concluded that the application of the applied solar chimney had succeeded in decreasing the H2S gas concentration in the surrounding air by 30 -40 % and inside the headwork by 50-60% for the screen room and from 70-80 % for the grit removal chamber that ease the work inside the headwork building to the labors and improve the environment with almost minimum cost. The application of activated carbon at the chimney top removed all the H2S gas from the effluent of the chimney and help in decreasing the H2S gas in the head works area by 70% at screen and 90% at grit removal chamber which make them inside the permissible limits for air content of such places. The affecting parameters on the system design are the inlet and top diameters of the chimney, the chimney height, the sewage flow in the manhole, the temperature inside the top of the chimney and the temperature outside the chimney. The study had concluded the following equation as the simulation one with error boundary + 7 % than the field measured data
