If you are looking for the cooling tower cleaning process, checklist and costs, this will be your guide!
Why Clean Your Cooling Tower?
Cooling towers need regular maintenance and cleanings, just like most equipment in a facility. Neglecting any maintenance or cleaning tasks can lead to the following issues with your cooling tower:
- Legionella Disease.
- Plugged up equipment.
- Decreased efficiency.
Towers that undergo regular cleanings/maintenance have been proven to be more energy efficient than those not receiving attention. Keeping your tower running efficiently will save energy consumption and manage overhead costs, at the same time.
Cooling Tower Cleanings
Any cooling tower cleaning project will typically consist of the following:
- Acid cleaning.
- Dispersant cleaning.
Acid cleaning is done in order to remove any rust that may be building up within the tower. Disinfection is performed to keep bacteria under control and as a Legionella risk-abatement. Dispersant cleaning is done last. This will loosen up deposits and strip biofilm.
- Inspect The Unit: Jot down notes on anything that looks and sounds unusual with the cooling tower. This will later serve as guideline for how to fix any potential issues.
- Disconnect Motor Switches: This is purely to ensure your safety while inspecting the tower. Of course, follow the recommended lock out procedures before attempting to perform any hands-on tasks.
- Inspect The Strainers: Clean any debris from the strainers, if possible. This will help guard against any unwanted materials entering the system.
- Inspect The Water Distribution System: Check the system for any dry areas over the fill coil section. Check the nozzles for either cracks or clogs if the surface is not completely wet.
- Flush Out Debris And Dirt: You can do this through the tower drain or sump strainer from the cold water basin. The goal here is to prevent dirt buildup.
- Check The Water Supply: First locate the predetermined water level by inspecting the makeup water supply. This is done to conserve water over time.
- Adjust The Bleed Rate: Make sure you know the local water quality regulations in your area ahead of time. Adjusting the bleed rate will block the accumulation of solid matter within the tower.
- Fix Tension Problems: The belt drive system can only function at the highest level when any tension issues have been resolved.
- Check Oil Quality: Follow the manufacturer’s advice by checking oil quality, level and shaft alignment for the gear drive system.
- Lubricate Bearings Of The Fan Shafts: This is done to guarantee proper operation. Do this task once every three months.
How Long Will A Cleaning Take?
A small to medium-sized system will typically take an entire day to fully cleanse. Generally, the acid cleaning is the longest part of this complex process.
How Much Does Cooling Tower Cleaning Cost?
A typical cleaning project for cooling towers will cost $10,000. Prices will range from $5,000-$15,000, depending on size and complexity of the project.
