THE BIOLOGICAL TREATMENT OF WASTEWATER: MATHEMATICAL MODELS

Thermophilic Biological Wastewater Treatment

Thermophilic treatment is one of the advanced treatment technologies used for the purification of high-strength wastewaters. Thermophilic systems are conventionally used for sludge treatment, but their ability to reduce COD to a great extent with sludge generation one-tenth when compared to the other wastewater treatment technologies, have favored its application for wastewater purification. Mo...

Genomics of biological wastewater treatment

Cleaning up wastewater from domestic sewage and industrial processes is essential for safeguarding public health and the environment (for an overview of wastewater treatment processes see http://en.wikipedia.org/wiki/ Sewage_treatment). Biological wastewater treatment plants (WWTPs) employing sludge represent one of the most widely used biotechnological processes, with more than 120 billion lit...

The Biological Basis of Wastewater Treatment

A mathematical model for the biological treatment of industrial wastewater in a reactor cascade

Many industrial processes, particularly in the food industry, produce slurries or wastewaters containing high concentrations of biodegradable organic materials. Before these contaminated wastewaters can be discharged the concentration of the biodegradable organic pollutant must be reduced. One way to do this is to pass the wastewater through a bioreactor containing biomass which grows through c...

Physico-Chemical and Biological Treatment of Olive Mill Wastewater by Rotating Biological Contactor (RBC) Reactors

The removal performance of total poly phenols and orthodiphenols (o-diphenols) content in olive mill waste (OMW) was investigated with a three stages cross flow laboratory scale rotating biological contactor (RBC) in the present study. Due to high COD and other pollutant in the original OMW, physico-chemical treatment was effected for COD and other pollutant reduction prior to biological tr...
