Relations Among Sludge Rheological Properties And Operational Problems In An Industrial Zone Wastewater Treatment Plant

The main objective is to examine how the viscosity values change in order solve problems frequently encountered transmission lines this study. Sludge samples from chemical and biological treatment process were taken two different stages of nearby industrial zone wastewater plant (IZWWTP). Physical, rheological properties sludge investigated seasonal periods (October February). pH, temperature, conductivity, total suspended solid, oxygen demand volatile solids determined first phase In second phase, shear stress rates using Brookfield DV-II+Pro viscometer. behaviors modelled Bingham, Ostwald Herschel-Bulkley. operating when increases, alternative coagulants may be preferred, type or amount changed process. pumps within facility should selected according sludge. Seasonal measures can reduce costs.
