00-11: Circular Hybrid Cooling Towers Microbiological Activity in Cooling SystemsHybrid cooling towers of the classical design with separate wet and dry sections have constituted a proven technology in the recooling field for approximately the past two decades. The round type of construction however is only used for high thermal performances, in particular for power stations, and is at present less well known. Another feature of this type of cooling tower is the separate machine sets allocated to the wet section and dry section
