I have a problem with scale which has caused the formation of Legionella bacteria in my water cooling towers.
How can I get rid of the bacteria most efficiently and quickly?
How should I change the temperature, water hardness and pH to prevent scale formation?

Oliver pretreatment with a water softener or reverse osmosis filtration would be an option for the scale. A good chemical water treatment program would be the other and solve both issues. Please call me to discuss at 708-539-2117. Eric Wallace

Lets first deal with removing the scale formation issue that is due to presence of calcium and magnesium salts in the water. A very effective technology using the template assisted crystallization tank system will bring the calcium and magnesium salts to the surface of the water, thus the salts will not adhere to the packing and scale formation will not occour.
As far as Legionella is concerned, you need to go to a shock dose of 100-200 ppm of chlorine dioxide. Once the tower is cleaned up, you need to go to constant dosing of chlorine dioxide at 1-3 ppm per day. The actual demand for chlorine dioxide needs to be established.
