Fouling characteristics of cooling tower water : pH effect

Creator:: Roy, Bhasker Vilva
Abstract:: The fouling characteristics of simulated cooling tower water flowing over a heated metallic surface has been studied. The bulk temperature of the water was maintained around 95°F. Mainly three different water qualities with respect to calcium hardness level were investigated. The pH was controlled by the addition of hydrochloric acid....

The effect of copolymer and iron on the fouling characteristics of cooling tower water containing corrosion inhibitors

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...

Fouling characteristics of cooling tower water containing corrosion inhibitors

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...

Deposition characteristics of magnesium silicate and calcium carbonate in cooling tower water

Creator:: Lee, Sai Heep
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...

Effects of water quality and surface temperature on the scaling characteristics of cooling tower water

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...

Calcium carbonate scaling in a deluged dry cooling system

Creator:: Barton, Kathleen Patricia
Abstract:: Scaling characteristics of calcium carbonate on a heated surface in a deluged dry cooling system were investigated. Bulk temperature of the deluge water was maintained constant at 90°F. Air flow velocity was maintained constant at 181 cfm., and deluge water flow was maintained at the minimum level that provided thorough...

Computer assisted design of humidification equipment

Creator:: Harvey, Glenn B.
Abstract:: A computer assisted design model, developed for undergraduate students to teach the basic principles of humidification design, is developed and presented. Beginning with the development of the differential equations, the conversion to numerical code is presented, followed by a series of applications to mechanical draft in cooling towers, natural draft...
