Cooling Tower Makeup Tank

Control of the water level in the cooling tower basin is via a level instrument of some description.

Cooling tower makeup tank.

Makeup water usually is added to the cooling tower basin. This should be located in the relatively still waters of the pump basin. 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. Rate of evaporation is approximately 1 of the circulation flow for each 10 f 5 56 c of rise.

Cycles of concentration. Therefore water treatment is always required in the make up water of a cooling tower. Calculate the amount of makeup water required for a cooling tower with following conditions. 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.

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. Total cooling water makeup water requirement evaporation loss drift loss blow down. Water treatment of make up water will depend on the source of water and ct manufacturer requirements.
