Summer is Heating Up - Top 5 Ways to Save on Cooling Tower Bleed
Author: Pat Smith - Service Manager
As the mineral concentration increases, the water’s ability to conduct electricity increases linearly. This means we can use conductivity as a proxy measurement to determine the relative concentration of minerals in the system water as compared to the incoming make up water. This calculation is called the Cycles of Concentration, or COC.
1. Maximize the Target COC for your System
2. Reduce Uncontrolled Water Loss
a) Poor level control resulting in overflow from tower basin or sump
b) Preventing overflow when system cycles off
c) Ensure all automatic control valves are working correctly
d) Inspect pumps to ensure the packing is not allowing water to leak from system to drain
e) Inspect tower drift eliminator operation
3. Use a Conductivity Based Bleed Controller
4. Pre-treat Make Up Water to Increase COC
The following table provides a qualitative comparison of the different considerations for each of the common pre-treatment methods for Great Lakes water quality only.
5. Utilize a Water Treatment Data Management System

Cooling towers work by taking advantage of heat lost to the atmosphere when water evaporates. As we’ve just reached the summer solstice, it’s officially peak season to find ways to improve your tower performance. Whether your cooling tower is used
The goals of cooling water treatment systems are to minimize corrosion, inhibit scale formation, control biological activity, avoid fouling, and minimize water consumption. Physical water treatment devices, often referred to as non-chemical devices
