6/2/2020 · COC = Make up water quantity / Blowdown water quantity The last formula gives you more accurate COC if you have flow measurement facility available for makeup & Blowdown water in the cooling tower. The cycles of concentration normally vary from 3.0 to 8.0 depending on the design of a cooling tower.Get Price
Boiler water must contain a certain amount of causticity i.e. Hydroxide alkalinity in order to accomplish three things: 1. To maintain a protective coating of iron oxide over the metal and thereby prevent certain types of corrosion. 2. To provide a proper environment for precipitation of desirable sludge materials. 3.Get Price
20/9/2019 · COC or the C ycles O f C oncentration 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.Get Price
These systems measure the boiler water conductivity, compare it with a set point, and open a blowdown control valve if the TDS level is too high. A number of different types are on the market which will measure the conductivity either inside the boiler, or in an external sampling chamber which is purged at regular intervals to obtain a representative sample of boiler water.Get Price

Blow-Down Valve. Blow-Down Valves are used to remove impurities from boiler water. The water is blown out of the boiler with force by the steam pressure within the boiler. It needs to be blown out at speed, so that solid impurities in boiler feed water are carried out with it. These concentrated solids would cause many problems such as Get Price
Cooling tower bleed-off/blowdown is the flushing of a portion of high mineral concentration cooling tower system water down the drain, while simultaneously replacing it with fresh water. This process dilutes the system water mineral concentrations that steadily increase due to water evaporation. Scale formation will occur if the concentration Get Price
