Why is chemical treatment of cooling towers needed?
Typically water treatment for cooling towers involves the use of: Scale and corrosion inhibitors – These chemicals are meant to reduce or eliminate contaminants, such as minerals, in your water supply that can result in blockages and deterioration in your system’s piping.
What is chemical treatment in chilled water system?
Closed chilled water systems need to be dosed with nitrite or molybdate based corrosion inhibitors to prevent the corrosion of chilled water pipes.
What is boiler chemical?
Steam Boiler Chemicals – These include Oxygen Scavengers, Amines, Phosphates, Polymers, and Alkalinity Builders. Oxygen Scavengers – Most common type is 38\%, pH < 4. Boiler Alkalinity Builders – Potassium Hydroxide or Sodium Hydroxide are the most common boiler alkaline products..
What is the purpose of glycol?
Glycol is a water-miscible coolant that is frequently used in heat transfer and cooling applications. It provides better heat transfer parameters than water, and can be mixed with water to provide a variety of heat transfer characteristics. Glycol comes in two varieties: ethylene glycol and propylene glycol.
How do cooling towers control pH?
What You Can Do to Balance Tower Water pH
- Determine Water Quality. Start by measuring the water’s pH, alkalinity, hardness and conductivity.
- Establish Target Cycles of Concentration.
- Monitor COC and Water Performance.
- Automate Your Processes.
- Protect Your Equipment.
- Work With Your Vendor.
What is chemical dosing system?
A chemical dosing system is a facility for automated injection of reagents into a wastewater network for the control of septicity and odour emissions. These systems are typically used at pump stations, sewer manholes, and rising mains.
What chemicals are in chilled water?
The most common chiller corrosion chemical is a closed loop nitrite, borate, silicate product. The second chemical is a cooling water biocide. The most common biocide used to control bacteria is gluteraldehyde and isothiazolin.
