Abstract

Dairy industries discharge wastewater which is characterized by high chemical oxygen demand, biological oxygen demand, total suspended solids and organic as well as inorganic nutrients. If discharged without proper treatment, they severely pollute the water bodies thereby affecting the aquatic flora and fauna. So the proper treatment of dairy wastewater needs to be done before its disposal and should be well documented. Of all the secondary treatment methods, inverse fluidization technique has promising features because of its simplicity, easy handling, low cost, better efficiency and controlled growth of biomass on carrier particles. The present work summarizes the characteristics of hydrodynamic behaviour of inverse fluidized bed system and the dairy wastewater treatment. Behaviour of bed in terms of pressure drop, solid loading and different phase fractions were studied experimentally and correlations were developed accordingly. The system parameters of dairy effluent like Biological Oxygen Demand, Chemical, Oxygen Demand, Total suspended solids and pH were varied at different concentrations and time intervals to find its reduction percentage.
