Econexis Engineering is one of the leading manufacturers and suppliers of advanced Multi Effect Evaporator (MEE) Systems, designed to treat and recover valuable resources from industrial effluents. These systems are widely used in chemical, pharmaceutical, textile, food processing, and other industries where wastewater treatment and zero liquid discharge (ZLD) are critical.

A Multi Effect Evaporator (MEE) is an energy-efficient system that uses the principle of evaporation and condensation to remove water from industrial effluent and concentrate the dissolved solids. The process involves multiple stages (effects), where the vapor generated in one effect is reused as the heating medium for the next effect, drastically reducing steam consumption and energy costs.
Feed Collection & Preheating:
The effluent from the process is collected in a feed tank and preheated using heat exchangers to improve evaporation efficiency.
Evaporation in Multiple Effects:
The preheated effluent enters the first effect, where it is boiled under vacuum conditions. The vapor generated in this effect is used as the heating medium for the next effect, and this continues across multiple stages — typically 3 to 7 effects.
Condensation & Recovery:
Vapors from the last effect are condensed into pure water, which can be reused within the plant or safely discharged.
Concentration of Solids:
The remaining concentrate (high TDS/TSS) is collected and either reused or sent for further drying, depending on the nature of the industry


High Thermal Efficiency: Optimized design ensures maximum steam economy and minimal power usage.
Corrosion Resistant Construction: Made with SS316L or Duplex steel for longer life in harsh chemical conditions.
Automatic Operation: PLC/SCADA-based control system for fully automatic functioning and real-time monitoring.
Compact Modular Design: Easy to install, maintain, and expand as per future capacity needs.
Low Maintenance & Operating Cost: Designed for durability and continuous operation.
Zero Liquid Discharge (ZLD) Compatibility: Can be integrated with ATFD (Agitated Thin Film Dryer) or Crystallizer units.
At Econexis Engineering, we combine innovative design, precision engineering, and sustainable technology to deliver world-class evaporation systems. Our MEE units are tailored to your effluent characteristics, ensuring compliance with environmental norms while recovering maximum reusable water.
