One of the most efficient methods for wastewater treatment is commonly known as Zero Liquid Discharge, abbreviated as ZLD. This approach is typically considered a final resort due to its highly effective nature. ZLD employs state-of-the-art equipment to restrict the presence of waste and pollutants in wastewater. As the name implies, the end result of this method typically yields water devoid of pollutants. Conversely, the primary objective of this approach is to optimize water recovery while minimizing wastewater discharge.
