Abstract

The insufficiency of clean water for today usage has been very critical case. This is due to increasing of population, modern urbanization and also pollution that can cause water source affected by contaminants. So, in order to overcome this problem, the interest is much in the filtering of roof-collected rainwater. One of the techniques was to treat the rainwater by UV irradiation and carbon adsorption. This study was carried out to investigate the effectiveness of bacteria and another contamination removal from rainwater through ultraviolet irradiation and carbon adsorption. The parameter tested for rainwater was E-coli, coliform, turbidity and color. The rainwater was taken from tile roof at the student hostel, UTP. The experiment was conducted for 2, 4, 6, 8, 12 and 24 hours continuous circulation passing through with UV lamp. The results for rainwater before undergo treatment was 1 MPN for E-coli, coliform 7.3 MPN, turbidity 1.97 NTU, color 5NTU and pH 7.76. After 24 hours treatment, the results for the treated rainwater was 0 MPN for E-coli, 0MPN for coliform, turbidity 3.19NTU, color 7.7NTU and pH 6.5. The treated rainwater was safe for domestic usage according to National Standard for Drinking Water Quality. The acceptable value for drinking water for drinking water is 0MPN/100ml for E-coli, coliform 0MPN/100ml, turbidity 5NTU, color 15NTU and 6.5-8.5 for pH.
