<p>Molasses, a brownish black viscous liquid, is a byproduct of the cane sugar process. It finds applications in various industries such as fertilizer production, animal husbandry, alcohol production, monosodium glutamate production, and the production of acetic acid. In Thailand, it is primarily used for alcohol production and as animal feed. However, molasses wastewater is characterized by high levels of biochemical and chemical oxygen demand, as well as suspended solids. Untreated release of this wastewater into the environment can lead to numerous environmental issues. Additionally, the presence of melanoidins in molasses wastewater makes its removal challenging, resulting in a dark colour of the treated water.
