This paper attempt to highlight the potential of biochar regarding water quality improvement in tidal swampland. Water quality of tidal swampland is influenced by tides, seasons and human intervention. At the beginning of the rainy season, the water quality of tidal swampland is poor (pH 2-3). In the dry season, it is quite good (pH >5), except in areas with poor drainage. Biochar can effectively reduce contaminants including heavy metals, organic contaminants such as pesticides, medicines and daily chemical products. Biochar is created by heating biomass to high temperatures under limit oxygen conditions in a process known as pyrolysis. Similar to the shape and colour of charcoal from natural combustion, biochar differs in its manufacturing process and function. Biochar can be made from a variety of feedstock such as crop residues, plant and animal waste. Previous researches reported the positive effect of biochar as a soil amendment and adsorbent.
