Abstract
Developing countries are confronted with general issues of municipal wastewater management and treatment. Untreated faecal sludges and wastewaters from septic tanks and traditional toilet are rejected into rivers and sometimes using for urban agriculture without any treatment to reduce the biorisk. Consequently, there are potential environmental and public health risks. In this study, a wastewater treatment plant prototype coupled with Moringa Oleifera seeds treatment was developed to evaluate their effectiveness for the reduction of faecal indicator bacteria and antibiotics resistant bacteria in domestic wastewater. Results indicate that our performed prototype system presents high capacity to reduce bacteria with abatements up to 99.34%. High reductions of bacteria load were obtained after add of Moringa Oleifera seeds into waters, with reductions varied from 36.6-78.8% for E. coli, 28.3-84.6% for Faecal coliform, 35.3-95.6% for Vibrio cholerae and 32.1-92.4% for total flora. Same effects of Moringa Oleifera seeds were noted for reducing antibiotic resistant bacteria, Extended Spectrum Beta-lactamases and Carbapenem-Resistant Enterobacteriaceae with abatements up to 98% for E. coli and faecal coliform, 100% for Vibrio cholerae and 91.96% for total flora. Our results supported high capacity of Moringa Oleifera seeds as an excellent alternative for pathogens and antibiotics resistant bacteria reduction/purification from domestic wastewater
