Evaluation of crosslinking degree on the integral membrane by using Rice Husk Ash (RHA) / Nurul Atirah Fitriah Mohd Zainuddin, Norin Zamiah Kassim Shaari, Nur Syazwanie Izzati Chik and Fazlena Hamzah

Rice husk ash (RHA) is a waste product from the harvesting and processing of rice that contains a high quantity of silica, approximately 95% after combustion. Membrane technology is being developed to remove impurities like heavy metals and dyes as the natural environment deteriorates and water supp...
