Statistical optimization of aeration and agitation for sewage treatment plant sludge treatment in stirred tank bioreactor

A 2-level full factorial design (22) with one central point was employed to determine the optimum agitation and aeration for effective bioconversion of STP sludge by pure bacterial culture through the removal of chemical oxygen demand (COD). A second order polynomial model was developed to determine...
