Cooling Tower Makeup Tank

Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near.

Cooling tower makeup tank.

Control of the water level in the cooling tower basin is via a level instrument of some description. Rate of evaporation is approximately 1 of the circulation flow for each 10 f 5 56 c of rise. A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Therefore water treatment is always required in the make up water of a cooling tower.

Suspended solids removal dissolved solids removal softening ph adjustment dosing of biocides for bacterial control dosing of anticorrosion agents. Calculate the amount of makeup water required for a cooling tower with following conditions. Cooling tower must be made up because the water level decrease by the time during operation. There are aspect that contribute to calculation of cooling tower makeup water.

Makeup water usually is added to the cooling tower basin. These valves which are often included as standard on cooling towers operate similarly to the float valve in a toilet tank. If the instrument is of the level displacer type it should be housed in a still well located in the pump basin. Installed inside the cooling tower the float portion of a mechanical make up valve floats atop the water in the cold water basin.

Water treatment of make up water will depend on the source of water and ct manufacturer requirements.
