1. The I 2 Air Fluid Protocol; The Eco-friendly method for the elimination of bio-fouling in heat exchangers.

2. The Problem Heat exchangers are the heart of any cooling system found in industry. Unfortunately, the efficiency of any exchanger can be compromised when geo- thermal wells or cooling towers become contaminated by bacteria of many kinds. Bacteria adhere to the walls of the exchanger and form a gelatinous coating known as bio-film. Bio-film causes a reduction in heat transfer through; Occluded space which increases temperature and pressure through decreased flow within the geothermal or cooling tower side of the heat exchanger. Thermal insulating matter on the plates impedes heat transfer. Pitting corrosion on plate surfaces reduces plate heat transfer coefficient. This increases temperature within the coolant water to the chiller. Additionally, bio-film and planktonic bacteria can move downstream to diffusion wells where occlusion occurs on screens and and in cooling towers where bacterial contamination occurs.

4. The Answer The APF Cleaning Protocol and I2 Air Infusor The APF protocol is used to clean the interior surfaces of the heat exchanger of existing bio-film. It is a once a month procedure that requires approx. one hour per month labor time and no disassembly of the exchanger. It consists of the following: First, voiding the exchanger of any standing water within the exchanger through the introduction of air using the APF manifold.

6. Second, introducing the I2 AFI cleaning solution. Third, provide continuous agitation. Fourth, liquefy bio-film. Fifth, remove cleaning solutions. Finally, start of normal water flow.

8. The cell wall is exposed continually to new low dose iodine within the air bubbles. Iodine is drawn into the cell and key amino acids in the respiratory chain are broken down. The bacteria is destroyed. The I2 infused air molecule eliminates free floating bacteria and bacteria resident in existing biolms. Iodine converts to Eco-friendly iodide and moves downstream.

9. The patented I 2 Air Fluid Infusor Cartridge produces I 2 infused bubbles that are dosed for accurate elution. are unaffected by water temperature, turbidity, mineral content or pH. converts to Eco-Friendly iodide after contact with bacteria. will not effect most materials. will have the same effect on microbes as much higher concentrations. are negatively charged.

10. Throughout the month, the plate walls are continually bathe in low dose I 2 bubbles which keep bio-films from forming in a various ways.

11. Turbulent bubbles lift and dislodge biofilm. Iodine liquefies biofilm. Bubbles prevent planktonic bacteria from adhering to plate surface.

12. The continual profusion of I2 infused bubbles keeps the plates clean providing optimal heat transfer. The bubbles continue on to the diffusion well screens and cooling towers where bio-film is eliminated at those sites.

13. The results! Diffusion well screens after 8 months! “Hi Mike, We have been running one 300 GPM supply well. We have left all 3 diffusion wells open. Each diffusion well has a capacity of 300 GPM. In order to determine if all 3 diffusion wells are working properly, we turned two off at a time so that we tested each diffusion well by itself to ensure that it was taking 300 GPM. All 3 took the 300 GPM of water without increases in incoming or outgoing pressure at the heat exchanger. I took that to mean that all 3 diffusion wells are working properly.”
