    Comparison Between Activated Carbon and Sand Filtration Method for Water Quality Enhancement: A Case Study
    (IOP Publishing, 2021) M R A A Chan; N Kasmuri; R Ahmad; R Santiagoo; S Ramasamy
    This study aims to determine the water quality status of Metropolitan Lake, Kuala Lumpur before and after the treatment of activated carbon and sand filtration method. Here, physical and chemical characteristics were conducted for in-situ and laboratory analysis. Temperature, pH, dissolved oxygen (DO), total dissolved solids (TDS) and turbidity of water samples were taken in-situ. Meanwhile, parameters of biochemical oxygen demand (BOD), chemical oxygen demand (COD), turbidity, total suspended solids (TSS), ammonia nitrogen (NH3-N) were determined in the laboratory.

    Enhancement of Water Quality using Natural Coagulant in Shah Alam Lakes, Malaysia
    (IOP Publishing, 2021) R A Hassan; N Kasmuri; R Ahmad; R Santiagoo; S Ramasamy
    This research aims to investigate the optimum condition of natural coagulant (Moringa oleifera) for the treatment of surface water from Shah Alam Lakes in Selangor Region, Malaysia. These lakes can be a potential source of water if water shortage occurs. At first, the characteristics of the water samples were determined. Later, the sample of surface water from the lakes was examined with the jar test for the coagulation-flocculation process using Moringa oleifera with different concentrations. The water quality parameterssuch as pH, turbidity, suspended solids, phosphorus and chemical oxygen demand were evaluated.
