Falling Film Evaporator

In falling film evaporator, water is distributed in tubes like a fine film layer on surface of tubes. Due to less wetting in surface and scaling, fouling materials will form a layer of insoluble scale that reduce its evaporation capacity. Feed vapour is separated in vapour separator. Use of falling film evaporator with multiple effects ensures high energy efficiency & is ideal for concentration of heat sensitive products, with low scaling tendency.
We installed many falling film evaporator at various capacity for various industries. Mainly falling film evaporator are suitable for handling reverse osmosis reject water and having more than 40,000mgl TDS. This system evaporates up to 90% of feed and gives concentrate 300gram per litre. This concentrate is dried in drier crystallized in crystallizer or handled with forced circulation with KWS pusher centrifuge.
