Electrocoagulation Treatment of Peat Water in Sarawak with Aluminium Electrodes

Water scarcity is still a major problem in Sarawak’s rural areas. Peat water is abundantly found in the rural coastal regions but peat water is associated with a distinct red-brown colour and unpleasant smell. As such, this research investigates the application of an electrocoagulation treatment sys...

Peat water is abundantly found in the rural coastal regions but peat water is associated with a distinct red-brown colour and unpleasant smell.
