Abstract

The objective of this research was to study physical and chemical qualities of surface water from Moon river, and tap water from Water Treatment Plant of Tansum Municipality, Ubon Ratchathani. Samples were collected in two periods including in the dry season (February 2016) and rainy season (June, July, and October 2016). The effects of coagulants types and concentrations, pH and ionic strength on removal of turbidity and dissolved organic carbon content in surface water were studied. It was found that surface water from Moon river, and tap water from Water Treatment Plant were in the range of water quality
except surface water collected in the rainy season. The effects on removal of turbidity and dissolved organic carbon content in surface water by chemical precipitation process were studied. The coagulants used in these experiments were ferric chloride, ferrous sulfate, aluminium sulphate and polyaluminium chloride. The jar test was used with 100 rpm rapid mixing for 10 minutes, follow by slow mixing 30 rpm for 20 minutes and setting for 60 minutes. It was found that the use of optimized type and concentration of coagulants and pH levels were affected on removal of turbidity and dissolved organic carbon content
in surface water while the ionic strength was affected in the condition without a little amount of lime. The addition of FeCl3 20 mg/L, FeSO4 10 mg/L, Alum 20 mg/L and PACl 20 mg/L at pH 7 could be high efficiency removal of turbidity and total organic carbon content in surface water. The percentages of removal of turbidity were 93.72, 50.27, 93.92 and 96.36, respectively. The percentages of removal of dissolved organic carbon were 79.54, 61.95, 79.02 and 79.32, respectively. Turbidity and dissolved organic carbon were in the quality of tap water by Provincial Waterworks Authority.
