Study of wastewater treatment based on the DAF for the small-scaled industry

Abstract

Most of the Mongolia industry scale is small sized industry comparing other country. Therefore, there is an important need of small scale pre-treatment plant of industrial wastewater in Mongolia. As nowadays requirement for protecting environment, all small scale industry have to install WWTP before discharge the wastewater into environment and sewerage network. The wastewater treatment plant at a poultry slaughterhouse comprises a dissolved air flotation (DAF) system. The DAF system at small-scale industries especially poultry wastewater treatment is designed to remove high concentration of organic pollution such as FOG, BOD, COD and TSS. Formulated on the literature, the DAF operation of the system removal efficiency at 300kPa pressure, PAC coagulation and anionic polymer is shown optimal result
