Cooling Tower Makeup Tank

There are aspect that contribute to calculation of cooling tower makeup water.

Cooling tower makeup tank.

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. Suspended solids removal dissolved solids removal softening ph adjustment dosing of biocides for bacterial control dosing of anticorrosion agents. Cooling tower must be made up because the water level decrease by the time during operation. If the instrument is of the level displacer type it should be housed in a still well located in the pump basin.

Control of the water level in the cooling tower basin is via a level instrument of some description. 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. Cycles of concentration. Rate of evaporation is approximately 1 of the circulation flow for each 10 f 5 56 c of rise.

Total cooling water makeup water requirement evaporation loss drift loss blow down. 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. Makeup water usually is added to the cooling tower basin.

Calculate the amount of makeup water required for a cooling tower with following conditions.
