The Evolution of Water Treatment
Chemical Water Treatment started in the 1940’s and there has been minimal improvements in last 10 years. Chemicals used to allow:
There are a lot of disadvantages associated with chemical water treatment:
NCD (Non-Chemical Devices)
Non-Chemical Devices were started in the 1970’s to alleviate the disadvantages listed above. Several technologies have been tried: Magnetic; Electrostatic; Catalytic; Pulsed Power; Kinetic Energy, Cavitation, etc. While they mean well, these technologies seemed to fall flat on issues like water savings, use of toxic chemicals, and scale & corrosion protection. Also there was a lack of residual treatment affects when machines aren’t running or left idle.
Zero Blow Down
Zero Blow Down began in the 2000’s to simplify the treatment of cooling water and to eliminate the use of chemicals. High Efficiency Softening (HES) removes all of the hardness ions before they enter the system. Concentration of natural chemistry provides corrosion and microbiological control over the water. Businesses can gain 7 LEED points with the corrosion protection with a natural “green” chemistry. It also eliminates all blow down from the cooling system, maximizing water savings. There is less than 2% loss of all make up water use. It is a simple process for any kind of water quality (recycled, RO reject, well, etc.) and there are no indexes to balance. It also includes 24/7 online monitoring of your system.
