Palm oil mill effluent treatment system comprising bioadsorbents derivable from palm oil mill waste and membrane

Abstract

The present invention discloses a system for treating effluent from palm oil milling, specifically palm oil mill effluent final discharge (POMEFD). The system includes three main components: a first adsorbent column using activated carbon derived from oil palm waste, a second adsorbent column using palm oil mill boiler ash, and a membrane filtration unit with a hollow fibre membrane. The effluent undergoes a series of adsorption processes followed by membrane filtration to produce treated effluent. This system effectively addresses discolouration and reduces the environmental impact of POMEFD. By utilising bioadsorbents like palm oil mill waste and boiler ash, the system enhances the sustainability of the palm oil industry while reducing costs, labour, and time. The approach promotes environmental responsibility and aligns with principles of waste minimisation and resource efficiency, making it a practical and cost-effective solution for wastewater treatment in the palm oil industry.
