    Effect of intake works corrosion on surface water quality and use of cathodic protection as a remedial measure
    (Federal University of Technology, Owerri, 2021-02) Udoh, Sunday Emmansion
    This research thesis on “Effect of Intake Water Corrosion on Surface Water Quality and Use of Cathodic Protection as a Remedial Measure” was aimed at studying the effect of intake works corrosion on surface water quality and how cathodic protection can be used to fix the problem while leaving the quality of the water at the intake point better. Primary and secondary data were collected for studies. Analysis of water sample collected at the intake point was carried out in the laboratory. Water quality parameters such as total dissolved solid (TDS) pH value, Temperature, dissolved oxygen (DO), Iron, Zinc, Aluminum, Flouride concentrations in mg/l, total hardness and calcium hardness were determined in the laboratory analysis. A corrosion rate of iron bars immersed in water for 7days, 14days to 49th day were determined. A simple mathematical linear relationship connecting the corrosion rate and total dissolved solids was established. It showed a simple linear regression equation that can be used to predict total dissolved solid whenever the iron concentration of the water sample is known. The result of the research showed that when the intake work members are made the cathode with the intake water serving as an electrolyte while a sacrificial anode is used to close the circuit, a simple electrolytic cell will be set-up, this will have the intake works members gain weight in the process thereby becoming cathodically protected and the water finally at the intake point becoming purer and clearer.
