Cycles of concentration definition

Cycles of concentration means the flow rate of water added to a cooling tower water system divided by the flow rate of water discharged from the cooling tower.
Sample 1Sample 2Sample 3
Cycles of concentration means the ratio of the concentration of total dissolved solids, other conservative mineral constituent, or electrical conductivity in the blowdown water to the concentration of this same constituent or electrical conductivity in the make-up water. This can be calculated by dividing the total make-up water by the total blowdown water.

Examples of Cycles of concentration in a sentence

  • Cycles of concentration represents the accumulation of dissolved minerals in the recirculated cooling water.

  • Cycles of concentration can be measured as the ratio of chloride levels in the recirculated water or blowdown relative to the chloride levels in the source water, or makeup water.

  • Cycles of concentration will be optimized, based on make-up water quality to obtain at least 5 to 7 ideally for efficient operation and cost effective conservation of water and treatment chemicals.

  • Cycles of concentration can be measured as the ratio of chloride levels in the recirculated water or blowdown relative to the chloride levels in the source water, or makeup water; or the make-up water volume divided by the blowdown volume (provided there aren’t other water losses); or the blowdown water conductivity divided by the make-up water conductivity.

Related to Cycles of concentration

  • median concentration means that half of the homes in a county are expected to be below this value and half to be above it. All houses contain some radon, and a few houses will contain much more than the median concentration. The only way to accurately assess long-term exposure to radon in a specific house is through long-term testing (sampling the indoor air for a year or more). The EPA recommends that all homes be tested for radon. Columbia University's "Radon Project" website offers help to homeowners in assessing the cost vs. benefit of testing a specific house for radon or modifying it for radon reduction (see http://www.stat.columbia.edu/~radon/).
