Prof. Dr. Water quality management Water -- Purification Water resources Master of Science in Civil Engineering This study aims to assess the quality of water resources in the Kedah North Canal, and its impact on chlorine demand in the Water Treatment Plant Arau Phase IV, Perlis. The study was conducted over 12 months from June 2014 to May 2015 based on the WQI, INWQS, and NSDWQ. The study found that the quality of water resources in the North Canal are in Class III. The main factors associated with this pollution is land use activities and the seasons change. Studies have shown that Pelubang, Jitra and Tunjang Station are major contributors of pollution such as ammonia, TSS, TOC, BOD, COD, turbidity, temperature, pH and DO. Iron and manganese pollution were the highest recorded at Tunjang and Jitra Station, while phosphate and nitrate pollution concentrated in Tunjang and Padang Sera Station. Analysis of water quality in the Water Treatment Plant Arau Phase IV shows the changes of water quality resources with a significant impact on the chlorine demand when the value of r = 0.75 and r2 = 0.56. The average of chlorine demand in D1 Station (Intake), D2 (Aeration), D3 (Sedimentation) and D4 (Sand filtration) were 2.48 mg/L, 2.31 mg/L, 1.98 mg/L and 1.74 mg/L. Analysis of water quality parameters and chlorine demand also exhibits a very strong relationship with r > 0.90, particularly by pH, ammonia, nitrate, phosphate, iron, manganese and TOC. This is followed by r > 0.70 by TSS, temperature, and turbidity, while DO exhibit the weakest correlation, r = 0.20. Multiple regression analysis showed predictor parameters for chlorine demand in D1, D2, D3, and D4 each consisting of TSS, TOC, manganese and ammonia. The conclusion is, the combination of land use activities and seasonal changes can affect and impact on the quality of raw water resources in the North Canal, Kedah thus affecting the chlorine demand present in the water treatment process at the Water Treatment Plant Arau Phase IV, Perlis. The higher quality of water resources, chlorine demand will decline, but when low-quality water resources will increase of chlorine demand. Therefore, the effectiveness of pollution control and water treatment process is very important to eliminate or minimize the potential precursor to cause demand to ensure that chlorine treated water supplied to consumers quality and safe. 2017 2023-05-23T03:56:24Z 2023-05-23T03:56:24Z Thesis http://dspace.unimap.edu.my:80/xmlui/handle/123456789/78790 ms Universiti Malaysia Perlis (UniMAP) Universiti Malaysia Perlis (UniMAP) School of Environmental Engineering
