    Life Cycle Design and Efficiency Strategy for Sustainable Membrane Technology
    (IOP Publishing, 2021) K K Razman; A W Mohammad; M M Hanafiah
    Life Cycle Assessment (LCA) is an assessment tool to evaluate the potential environmental impact of a system or product throughout its life cycle. Results from LCA provides an insight on developing a more sustainable system while identifying its environmental hotspots. With recent advancements in membrane treatment systems especially for wastewater treatment (WWT), there is a rising interest in its sustainability aspect. Thus, it is crucial to review on previous published studies to highlight the challenges and achievements in implementing LCA for the membrane system. Hence, this paper presents a review of 33 recent papers published from year 2017-2020 conducting LCA on membrane systems for WWT.

    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.
