To study the effectiveness of aeration units, we have selected the Lower Lake, which is situated in Bhopal, the capital city of Madhya Pradesh, India. The Lower lake (Lat 230 16' 00" N and Long 770 25' 00" E ) is an artificial lake. It is situated towards the east end of the Upper lake and is an integral part of the latter. It has a small catchment area 9.60 Sq.Km. and water spread of 1.29 Sq.Km. The extent of water pollution has been found to minimize by aeration units. The physico- chemical parameters like pH, dissolved oxygen, Biochemical Oxygen Demand (BOD) Chemical Oxygen Demand (COD) nitrate, phosphate and bacteriological status have studied to ascertain the effectiveness of aeration unit. The floating fountain cum ozonizer installed at Neelam park station is more effective unit as it increases Dissolved Oxygen Concentration, reduces Biochemical Oxygen Demand (BOD) and Chemical oxygen demand and the ozonizer installed at Khatlapura is also effective to increase Dissolved Oxygen concentration in the hypolimnion and control total coliform (MPN). Therefore, the present study indicates the aeration units especially dual systems are very effective in improving the water quality of a degraded water body.
