What type of water is used in cooling towers?
make-up water Water
Water is widely used as a medium for cooling, due to its good heat transfer capacity.
What hardness should cooling tower water be?
As a general rule of thumb, the calcium hardness in the cooling tower should be maintained within the range of 350 to 400 ppm on a non-acid treatment program. If the makeup water contains, say, 100 ppm calcium hardness, the cycles of concentration are restricted to 3.5 to 4.0.
What is the pH of cooling water?
between 8 and 7
An ideal coolant pH between 8 and 7. First of all, pH (hydrogen potential) measures the acidity or basicity of a solution. For example, for coolant, it should be between 8 and 7. In this regard, it is important to check the pH of the coolant regularly.
Is RO water good for cooling tower?
Utilizing reverse osmosis water within the cooling water industries can save on the cooling tower chemicals. Low operating cost, compact size, reduced footprint, and high quality production of freshwater.
How do you calculate water for a cooling tower?
Cooling tower calculation
- Cooling tower makeup calculation. Water Make Up = D + E +B.
- Evaporation Loss = 0.00085 * 1.8 * C * Δt. C = Circulating water in.
- Blowdown : B = E = Evaporation Loss in.
- COC = Cycle of Concentration.
- Capacity of cooling Tower.
What is COC water?
COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower.
What is M alkalinity in cooling water?
Titration of the cooling water to pH 4.5 gives the so- called «m-alkalinity» (methyl orange alkalinity), a measure of total alkalinity. Below this pH, there is no more alkalinity present, only free acid (H+), carbonic acid (H2CO3), and CO2.
