Abstract

Peat is a wetland region in Indonesia with a very high water storage capacity. However, the amount of humic compounds obtained from the accumulation of organic substances in peat makes the water unable to be used for daily purposes. Peat water treatment with several methods has been carried out, such as coagulation, electrocoagulation, flocculation, and filtration. However, the result of clumping or filtering in such a way raises new environmental problems. One method which effective and efficient used in peat water treatment is photocatalytic. Several materials based-semiconductor was developed as a photocatalyst, another modification of photocatalyst is combining the adsorbent as a porous supporting photocatalyst which can improve its performance.

Abstract

Indonesia has the largest distribution of peatlands worldwide and is spread over Sumatra, Kalimantan, and Papua islands. Peatland is one of the land resources with a hydrological function and can store water in the form of peatwater. Peatwater is brownish-red due to high dissolved organic matter, especially in the form of humic acid and its derivatives, high organic matter content, low pH, and low cation content. Peatwater is classified as polluted water, unsuitable for consumption, and cannot be used directly as drinking, bathing, or washing water. The Mixed Matrix Membrane Fabrication method is expected to be used for peatwater purification by adding silica filler from rice husk ash. Rice husk has a high silica filler content of >90%. The higher the silica level, the better the material absorbs harmful chemical compounds in peatwater, one of which is humic acid.
