Abstract: A modified activated sludge process, called the oxic-settling-anaerobic (OSA) process, achieved effective reduction in excess sludge production. Its key feature is the insertion of a sludge holding tank in the sludge return ...

Abstract: An Eulerian finite element model is presented that simulates orthogonal metal cutting. The model predicts chip geometry and temperature distribution in the workpiece, chip, and tool without the ...

Abstract: The electrochemical oxidation of phenol was studied using a
