Effective Treatment of Chocolate Industry Effluent Using Waste from Biocosmetic Industry

Abstract

The revaluation of industrial wastes has great environmental benefits. Bio‐cosmetic industry has known huge success worldwide and eventually large amounts of wastes are produced. A bio‐cosmetic industrial waste (BCIW) was experimentally evaluated for its efficiency compared to Moringaoleifera seeds powder (MOSP) and aluminum sulfate (alum) coagulants to treat chocolate industry wastewater (CIWW). Confectionery industrial wastewater is commonly defined by high turbidity, chemical oxygen demand (COD), total solids, total volatile solids, and carbohydrates that may cause detrimental environmental pollution if discharged directly. M.oleifera seeds are largely studied by several researchers and alum is widely used in the industrial wastewater treatment due to its performance and low price. However, industrial bio‐cosmetic waste has never been used as a coagulant in previous studies. In this study, the removal of turbidity and COD from CIWW is investigated in relation to coagulant concentration and coagulation pH. It is found that the industrial waste performs better than MOSP and alum in removing turbidity and COD. The results show that BCIW removes more than 99% turbidity and over 87% COD at optimal treatment conditions of coagulant concentration and pH. The findings suggest that the BCIW has the potential to be utilized as a bio‐coagulant for treating CIWW.

Unveiling the dye adsorption capability of Moringa oleifera functionalized hybrid porous MOF–GO composites: in vitro and in silico ecotoxicity assessment via antibacterial and molecular docking studies

“…[21][22][23] Various parts of the drumstick tree (Moringa oleifera), such as roots, stems, leaves, and husks, are a rich source of diverse compounds, including alkaloids, phenolics, carbohydrates, tannins, flavonoids, glycosides, phenols, proteins, and terpenoids. [24][25][26][27] These compounds can be extracted and utilized as functional groups on the surface of non-bonded metal and oxygen sites on the composite surfaces. 28 Applying these functionalized adsorbents holds great promise in the selective removal of specific dyes present in wastewater, making them effective adsorbents for improving water quality.…”
