Abstract

The volume of industrial wastewater is expected to double by 2025 resulting in an increase of contaminated freshwater resources [1]. The susceptibility to water scarcity for residents of industrial manufacturing-based countries increases due to discharge of untreated industrial wastewater to surface water sources. Currently, severe water scarcity affects half a billion people year-round and 1.78 billion people at least 6 months out of the year. As a country dependent on river water for human consumption, crop irrigation, fisheries, transportation, and conservation biodiversity, Bangladesh has a population of 130 of 152.5 million people experiencing water scarcity [2-4]. Bangladesh also experiences an economy driven by a heavy industrial wastewater producing industry. The 1.8-billion-dollar generating industry of leather production not only consumes large quantities of water but discharges extreme quantities of toxic wastewater without prior treatment [4-5]. This is a review of the leather industry’s role in water pollution.

Summary of research results to be presented

Industrial wastewater is responsible for the transformation of 16% (628,480 L) of global freshwater withdrawals to becoming toxic wastewater. Tannery process consumes between approximately 82-147 million liters of water annually. It produces wastewater with increased BOD, COD, SS, TDS, and chromium/sulfide concentrations. Water treatment of tannery wastewater can open the possibility to reuse water for industrial processes, reduce environmental and health impact upon discharge, and produce byproducts that can be further utilized for efficiency.
