Abstract

This case study presents the successful implementation of a vacuum distillation system at PPLi for treatment of high-concentrated waste, with a focus on water recycling. The vacuum distillation unit employs advanced thermal heating and evaporation processes, facilitated by reduced pressure, to effectively separate contaminants from the waste stream. Operational parameters, including waste type, feed rate, temperature settings, and vacuum level, were meticulously optimized to achieve optimal treatment efficiency. The study conducted experimental trials over six months, rigorously monitoring and analyzing the treated water quality for chemical composition, total dissolved solids (TDS), and other relevant parameters. Results showed a remarkable reduction in TDS and chemical contaminants, ensuring compliance with stringent regulatory standards. Additionally, the case study explored potential reuse and recovery options for the separated concentrated waste. Laboratory tests examined the feasibility of utilizing the waste residues for energy generation or as raw materials for other processes. The successful implementation of the vacuum distillation system at PPLi underscores its practicality and effectiveness in treating high-concentrated waste while facilitating water recycling. This achievement represents a significant step towards reducing environmental impacts associated with waste disposal and conserving precious water resources. The insights gained from this study serve as a valuable reference for industrial facilities seeking sustainable waste management solutions, fostering a circular economy approach and promoting responsible environmental stewardship.
