Abstract:

High level of nitrates from palm oil mill wastewater causes pollution in the environment. The reduction in its content was done using natural and activated Kaolin clay. The aim of this research is to use local abundant and low cost adsorbent in the reduction of nitrates. Mineral logical composition of clay was done using X-ray diffractometer, standard methods America Public Health Association (APHA) standard was used UV-Visible spectrophotometer with a percolating media containing clay stone in ratio 3:1. The nitrate level in palm oil effluent 55.70mg/L after treatment it was reduced to 5.31mg/L for natural Kaolin and 3.4mg/L for activated kaolin. Based on World Health Organization (WHO) standard it is high enough to cause pollution. It was shown that kaolin has the capacity to reduce nitrates from palm oil mill wastewater when activated kaolin has greater capacity for nitrate removal than natural kaolin.
