Distillery spent wash (DSW) is a highly challenging environmental by-product generated during the distillation process in ethanol production. Its composition, characterized by high organic content, significant water pollution potential, and large volumes, poses substantial ecological risks. Traditional treatment methods, such as biological processes and conventional evaporation, are not only energy intensive but also requires large footprint and financially burdensome. This paper presents the application of Mechanical Vapour Recompression (MVR) based Low Temperature Evaporator (LTE®) technology as an innovative, energy-efficient solution for the concentration of DSW. By optimizing evaporation through the reuse of generated vapour, MVR significantly reduces energy consumption, operational costs, and the carbon footprint compared to conventional methods. The paper outlines the MVR process, detailing key stages such as preheating, vapour generation, and subsequent concentration of spent wash. The effectiveness of MVR-based LTE® is demonstrated by a case study from Kibos Sugar in Kenya, which achieved high water quality, low chemical usage (for CIP only), and significant operating and maintenance cost savings. The paper discusses the potential of LTE® technology to address environmental concerns while enhancing operational sustainability and efficiency. This study underscores the transformative potential of MVR technology in revolutionizing distillery wastewater treatment, offering a sustainable pathway for the management of distillery effluents.
