The water quality in surface water depends upon geological factors, morphological factors, vegetation, in-dustrial and agricultural land in its proximity. Turbidity is one of the most unaesthetic measures of water quality in surface water [1, 2]. The turbidity in water is due to suspended and colloidal matter including clay, silt and finely divided organic matters [3]. Turbidity in water affects aesthetics adversely [4]. It also brings unpleasant taste and foul odour. Turbidity also affects water treatment process including disinfection as well as increasing the cost of treatment. In addition, turbidity is harmful as turbid water inhibits respiratory processes and reduces visibility, so it is very essential to minimize the turbid level of surface vvater. The varia-tion in temperature in different seasons also affects the chemical characteristics of water. High tempera-ture also decreases gas solubility and respiratory rates.
