COMPARISON OF KINETIC AND STATISTICAL MODELLING APPROACHES FOR CONTINUOUS ELECTROCOAGULATION FOR PEAT WATER TREATMENT DESIGN SIMULATION

In Sarawak, peat water is one of the potential raw water sources as a domestic water supply, particularly for the communities of the rural areas that do not have access to the municipal water supply. However, the peat water must be treated before it is used as a water supply due to the high ac...
