Condensate and solids (salts) recovery using MVR and Wastewater Recycling MEE
MVR BASED EVAPORATION TECHNOLOGY
No heat generation and rejection
- Least carbon footprint
- Least manpower required
- No blowdown from cooling tower reduces load on effluent plant
- No RO system required
- Operates on low ΔT in the range of 1-3ºC
- Very low power consumption in evaporation.
- Most effective system with lowest condensate and solid recovery cost
- Recovery of energy in the form of bioenergy or fuel for boilers
- Recovery of nutrients, can be used as fertilizers in fields
- 90-95% water recovery from effluent

Research
The conventional Effluent Treatment Plant (ETP) system involved Multiple Effect Evaporators (MEE) operating on High-Pressure (HP) steam for effluent concentration. However, to reduce energy consumption and operational costs, the MEE train is discontinued, and alternative methods for effluent concentration are implemented.
In the previous ETP system, excess low-grade vapors generated during the concentration process were often dumped to surface condensers and cooling towers. With the discontinuation of the MEE train, there is no longer a need for this practice, eliminating the discharge of vapors to the atmosphere.
