Abstract Reduction of thermal and organic pollution by heated water from the direct contact condensers on vacuum evaporators in a beet sugar factory was studied by treating samples in a laboratory-size packed column. Cooling of the water, bio-oxidation of dissolved organic matter (primarily sucrose), and removal of nitrogen (primarily as ammonia) were achieved by counter-current contact between descending water and a rising air stream. Organic content, as measured by COD values, was reduced. The cooling data were correlated by the equation, K(y) A = 0.54 G where K(y)A IS POUNDS OF WATER EVAPORATED PER HOUR, FT3 OF PACKING, UNIT HUMIDITY DIFFERENCE, AND G is lbs air flow per hour, ft2 cross section. Adjusted temperature change in the column ranged from a low of 22 degrees (122 degrees in, 100 degrees out) to a high of 42 degrees (121 degrees in, 79 degrees out).
Highlights Notes Appraises the feasibility of reducing both thermal and organic pollution from the condenser water of beet sugar factories by using a cooling tower in a closed system in which biological oxidation of sugars, etc. is maintained.
