<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.

However, molasses wastewater is characterized by high levels of biochemical and chemical oxygen demand, as well as suspended solids.
