Abstract
Clarity performance variables of polluted water at different conditions of bioflocculation were studied through a set of laboratory experiments using the shake flask technique. The study was based on the relationship between physical properties of developed bioflocs and some environmental parameters. The physical properties included floc sizes and numbers, solution turbidity and the ratio of unsettled floc numbers (ufn) to total floc numbers (tfn) and settled floc volume (sfv) to total floc volume (tfv). The environmental parameters were the application of different sources of wastewaters, using of filamentous, floc forming, and natural bacteria, mixed at different speeds. The results indicated that various sources of wastewater mixed at different speeds, in the presence of various categories of bacteria allowed the development of flocs possessing a wide range of physical properties. Clarity performance was directly proportional with the ratio of sfv/tfv and inversely proportional with ufn/tfn. These ratios, on one hand, and with the floc sizes, numbers and solution turbidity, on the other hand, were discussed from the view point of their importance in clarity performance efficiency measurement of wastewater.
