Ecological and Comparative Performance Studies on High-rate Sewage Filter Media
… discharge to inland waters ,using conventional biological filtration, The use of two stage filtration has been shown to produce effluents of a higher standard than single stage filtration. This investigation was undertaken to determine the optimum conditions for two stage filtration where the …

Ecological studies on high-rate biological filters with special reference to microbial biosynthesis and nitrification
… nitrification was achieved. Fungi dominated the biological film of the primary filters, with invertebrate grazers having little influence on film levels. Ponding did not arise, and modular media supported lower film levels than random-fill types. Secondary filter film levels were low, being …

The Kinetics of Particulate Substrate Utilization by Bacterial Films
… oxygen demand (PCOD) from wastewaters in biological film systems. In this context, organic particles that are maintained in suspension (i.e., not removed during normal settling) are the focus of experimentation, modeling, and discussion. The goal of this research project is to study the …
