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.
Mainly falling film evaporators are suitable for handling reverse osmosis reject water and having more than 40,000mg/l TDS. This system evaporates up to 90% of feed and gives concentrate 300gram per litre.
