Abstract
The tanning industry is a major source of wastewater containing complex organic contaminants, which is crucial to the international leather trade. This article takes a deep dive into the topic of treating tannery effluent by focusing on trace organic contaminants, the dangers they pose, and the cutting-edge techniques used to get rid of them. Dye, heavy metals, sulphides, and other harmful organic compounds are only some of the organic chemicals commonly found in tannery effluents. Due to their propensity for bioaccumulation in aquatic environments, these pollutants offer a substantial environmental problem and raise concerns for human health. In this article, we will examine the origins, toxicity, and persistence of trace organic contaminants often detected in tannery effluent and their identification and characterization. Stressing the importance of strict wastewater treatment techniques, it investigates the ecological and health dangers posed by these toxins. In light of these difficulties, cutting-edge strategies for eliminating trace organic contaminants from tannery effluent are carefully evaluated. Physical, chemical, and biological processes, such as advanced oxidation processes, adsorption, membrane filtering, and biological degradation procedures, are all included in this category of treatment methods. The review analyses the efficacy, practicability, and scalability of various techniques in the context of treating effluent from tanneries. Future possibilities and new trends in tannery wastewater treatment are also examined, such as deploying decentralized treatment systems, incorporating sustainable and environmentally friendly technologies, and the possibility of resource recovery from tannery effluents.
