Salinity Reduction of Borneo Tropical Brackish Peat Water with Electrocoagulation Treatment

Sarawak located on Borneo Island has vast availability of brackish peat water sources especially in some coastal rural areas. However, brackish peat water is currently underutilized as the source for water treatment plants in the state due to excessive salinity levels. As such, this study aims to in...
