MEE Plant, also known as Multiple Effect Evaporator Plant, is a type of Zero Liquid Discharge (ZLD) plant used for treating wastewater. In this plant, wastewater is evaporated using multiple stages of heat exchangers, which results in the separation of solids and water. The evaporated water is then condensed and recycled back to the process, while the solid residue is disposed of as a dry material.
MEE plants are widely used in industries such as textiles, chemicals, pharmaceuticals, and paper mills, where the discharge of wastewater with high TDS (total dissolved solids) is not permissible. By utilizing MEE plants, industries can achieve complete water reuse, zero liquid discharge, and compliance with environmental regulations.
MEE plants come in various designs, including horizontal and vertical configurations, depending on the nature of wastewater to be treated and the required capacity of the plant. The selection of MEE plant design also depends on factors such as energy consumption, space availability, and capital cost.
MEE plants offer several benefits, including cost savings on water and wastewater disposal, reducing the environmental footprint, and enhancing corporate social responsibility. However, these plants also require a considerable amount of energy to operate and maintain, and they may not be feasible for smaller-scale operations.
