Another successful commissioning of a self-cleaning fluidized bed heat exchanger – the KLAREN system – in a waste water evaporation plant.
The heat exchanger converted to the KLAREN system is the 1st stage of a 4-effect evaporator train to treat waste water from a plant producing dyes for textiles. The heat exchanger earlier experienced severe fouling by salts of calcium, magnesium and silica.Due to fouling the evaporation capacity of the plant reduced to 50% in 20 days and the plant required cleaning of tubes. Subsequent to the commissioning with Klaren system the plant is operating at design evaporation capacity under stable conditions of the fluidized bed. With the KLAREN system, we make evaporator plants more sustainable.
