    Water Quality of Rooftop Rainwater Harvesting System (MyRAWAS)
    (IOP Publishing, 2021) N U M Nizam; M M Hanafiah; M B Mokhtar; N A Jalal
    This study was conducted to determine the quality of rainwater harvested collected directly from rooftop. The quality of the rooftop rainwater was taken in three consecutive months and the water quality for before and after treatment was measured and compared. Commercial activated carbon was used to treat the rainwater obtained from the rooftop. The water quality was compared with the Water Quality Index (WQI) and the National Water Quality Standards (NWQS). The parameters involved are pH, temperature, conductivity, dissolved oxygen (DO), total suspended solids (TSS), ammoniacal nitrogen (NH3-N), biochemical oxygen demand(BOD), chemical oxygen demand (COD), E.coli and total coliform bacteria.
