Augmentation of pesticides in activated sludge

Abstract

Activated sludge processes are the main technology used to treat organic wastewater. In the activated sludge have the contents of bacterial that is come from biological process. This process important in the system of wastewater because of the function is to treated sewage and industrial wastewater using air and biological floc composed of bacterial and protozoa. The effectiveness of the activated sludge has been studied with regard to augmentation of Metaldehyde representative of pesticide available on agricultural market. In order to compare the effect of different concentration of metaldehyde on the microbial growth in activated sludge. An agricultural industry contributes the high quantities of toxic pesticide into the environment. In this research, the bacterial can be detected was coccus, this bacterial was used to assess the potential of augmentation of pesticide can be treated in the different concentration of metaldehyde. During the experimental studies, the growth of bacterial for five samples with different concentration of metaldehyde shows the optimum growth is on control test (without metaldehyde) and the concentration of lower metaldehyde. However, at higher concentrations the bacterial count decreased but no death occurred. Based on the result can analyse the factor of growth and the study finding indicate that bacterial cannot be used to treat the high concentration of metaldehyde.
