Abstract

Large quantities of attached algae grow in shallow urban rivers that receive nutrientenriched effluent from secondary sewage treatment plants. Deterioration of water quality caused by respiration and detachment of attached algae is observed in these rivers.<BR>The kinetics of growth and detachment of attached algae in a circulation-type artificial river are studied in order to determine parameters involved in a water-quality simulation model of shallow and polluted rivers.<BR>First-order rate constant of algal detachment was found to increase with aging of attached algal community. And on the basis of the fact that only this surface layer of attached algal community (about 0.2g chlorophyll-a/mm²) receives sufficient light for growth, a kinetic model for the growth and detachment of attached algae is defined.
