Introduction Industrial wastewater treatment has become a critical priority for modern manufacturing industries, especially in sectors like pharmaceuticals where wastewater is highly complex and potentially hazardous. This case study highlights the successful design, installation, and operation of a 10 KLD Effluent Treatment Plant (ETP) for Renata Ltd, a leading pharmaceutical company in Bangladesh. The project was executed by V Aqua, a well-established wastewater treatment solutions provider, known for delivering customized and efficient ETP systems across South Asia. The primary goal was to build a compact, cost-effective, and high-performance system capable of treating pharmaceutical wastewater while ensuring strict compliance with environmental regulations.
