Creator:: Santoso, Elisabeth
Abstract:: The fouling characteristics of cooling tower water containing various corrosion inhibitors and other additives on heat transfer surface have been investigated. Corrosion inhibitors investigated included zinc-chromate and phosphates. In addition, additives including polyacrylate and phosphonate (HEDP and AMP) were used to determine their effectiveness as antifoulants. The tests were conducted...

Creator:: Abu-Al-Saud, Abdullah A.
Abstract:: Various antifoulant treatment programs and the considerations necessary for the effective use of such programs were examined. Two different groups of tests, with and without iron contamination, have been carried out on the effectiveness of several of the state-of-the-art copolymers (PA, HEDP, AA/HPA, AA/MA, SS/MA and AA/SA) in the inhibition...

Abstract:: Scaling characteristics of calcium carbonate on a heated surface in cooling tower water was investigated. Bulk temperature was maintained constant at 95°F. Flow velocities and surface temperatures ranged from 3 ft/sec to 10.3 ft/sec and from 105°F to 170°F respectively. City water was used as make-up for two different water...

Abstract:: Deposition characteristics of magnesium silicate and calcium carbonate on a heated surface in cooling tower water using city water as make-up was investigated. Flow velocity, bulk temperature and calcium hardness were maintained constant at 5.3 ft/ sec, 95°F and 150 ppm as CaCO₃ respectively whereas surface temperature varied from 105°F...

Creator:: Lahm, Lawrence
Abstract:: The fouling of cooling tower water was investigated as a function of heater surface temperature and water quality. In particular, the effects on fouling of the addition of calcium in excess of the amounts required for saturation were examined. First, the average bulk water temperature was 97 ± 1 degree...
