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....

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...

Friction losses for water flowing in non-circular ducts

Creator:: Mohandes, Abdolhosein
Abstract:: Friction factors were measured for water flowing in ducts made up of two rods held between two flat plates. Three rod diameters of 0.50, 1.00 and 1.50 inches were used. The spacings between rods varied from 0.0 to 0.32 inch. It was found that the concept of hydraulic diameter was...

Calcium carbonate scaling characteristics of cooling tower water

Creator:: Coates, Kenneth Edwin
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...

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...
