The multiple-effect evaporator combines two or more evaporator bodies to save fresh steam, which is condensed in the first-effect heat exchanger only. Water evaporated in the first-effect vapor body is condensed in the second-effect heat exchanger, which provides energy for the evaporation in the second-effect vapor body (and so on for next effects). Vapor from the last effect flows to a condenser and condensed water can be recycled or ruse. MEE can be arranged in multiple combinations viz. Forces Circulation, Falling Film, Rising Film with ATFD. Additionally can be attached with TVR or MVR for more savings on Fresh steam.
Applications of Multiple Effect Evaporator:-
Effluent Treatment: Industries like Chemical, Pharmaceutical, Textile, Dyeing, Breweries, Automobiles, Milk, Food industries etc, generates process effluents which are harmful to the environment. These effluents generally consist of water in huge amount and waste (contaminants). By evaporating the water from the effluent using MEE system results in the recycling of water.
Reverse Osmosis / Desalination: Reject of RO / Desalination have a huge amount of water. With MEE the water can be recycled.
Chemical Industry/ Pharma Industry: For the production of product the desired concentration is required or desired material need to be separated. Using MEE system desired concentration is achieved.
Milk Industry: Milk can be concentrated in the MEE system.
Sugar Industry: Sugar cane juice can be concentrated with MEE system.
Food industries: Tomato juice concentration, Sausages, Fruit juice concentration can be done in MEE system.
