The Cooling tower is installed where the continuous heat rejection is required. Like process plants. Type is depends up on use & water property.
Range is the difference of cooling water inlet and cooling water outlet temp
The process used for cooling water in a cooling tower is evaporation. Hot water is distributed over the fill material in the tower, allowing it to come into contact with air. As the water passes through the fill, some of it evaporates, taking away heat and cooling the remaining water before it is collected and circulated back into the system for cooling.
The return water temperature of a cooling tower typically ranges from 75°F to 95°F (24°C to 35°C), depending on the specific application and system design. This temperature reflects the water that has absorbed heat from the processes being cooled and is returning to the cooling tower for re-cooling. Factors such as ambient air temperature, humidity, and the cooling tower's efficiency can influence the exact return temperature. Properly designed systems aim to optimize this temperature for efficient cooling and energy use.
Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat fromcooling water. The make-up water source is used to replenish water lost to evaporation. Hot water fromheat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units for further cooling. Cooled water is needed for, for example, air conditioners, manufacturing processes or power generation. A cooling tower is an equipment usedto reduce the temperature of a water stream by extracting heat from water and emitting it tothe atmosphere. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly (Figure 1). Cooling towers are able to lower the water temperatures more than devices that use only air to reject heat, like the radiator in a car, and are therefore more cost-effective and energy efficient.
The only thing that I've heard of with "wet cooling" in, is a wet cooling tower. A Wet Cooling tower for the closed-circuit cooling of water where the water to be cooled comes into direct contact with the cooling air dissipating heat by evaporation and air heating. The air draught required for cooling can be induced by fans or by the natural effect of the stack of the cooling tower building (natural draught cooling tower).So I don't know if that answers your question or not, but i hope it helps...
The system you are referring to is known as an evaporative cooling tower. It works by using the latent heat of vaporization to cool the air as water is sprayed into the tower and evaporates, absorbing heat in the process.

Typically this would involve standard titration and colourmetric techniques, which involves analysis and monitoring of the cooling tower.
Cooling tower blowdown is the process of removing a portion of water from a cooling tower system to control the concentration of dissolved solids and impurities. As water evaporates in the cooling tower, it leaves behind minerals and contaminants, which can accumulate over time. Blowdown helps maintain water quality, prevent scaling, and ensure efficient heat exchange. By regularly discharging a small volume of water, the overall system remains balanced and operationally effective.
Water in a cooling tower is cooled primarily through the process of evaporation. As warm water is distributed over fill material, a portion of it evaporates, which removes heat from the remaining water. This heat exchange lowers the temperature of the water that circulates back into the system. Additionally, the cooling effect is enhanced by the airflow through the tower, which facilitates the evaporation process.
