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. Iron, sulfur and other species of 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. Additionally, bio-film and planktonic bacteria can move downstream to diffusion wells where occlusion occurs on screens and in cooling towers where bacterial contamination occurs.

The Answer The APF Cleaning Protocol and I 2 Air Infused mixed media. 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.

Second, introduce the I2 AFI cleaning solution. Third, provide for continuous 30 min. agitation. Fourth, liquefy bio-film. Fifth, purge exchanger of cleaning solutions. Finally, start of normal water flow. Note: cleaning solution is retained only in the exchanger and not allowed into the injection well. This is an Eco-friendly protocol.

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

Turbulent bubbles lift and dislodge bio-film. Low dose Iodine reduces microbial content Bubble flurry prevent planktonic bacteria from adhering to plate surface. Bubbles impart low dose iodine into water for downstream disinfection of cooling tower and diffusion screens

The patented I 2 Air Fluid Infusor Cartridge produces I 2 infused bubbles that are dosed for accurate elution. Elutes only grams per month into water stream. Adjustable based on need and standards. 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.

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.

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.

Does it really work? 300 GPM system, plate heat exchanger/ geothermal well; Inlet pressures average 13 psi and outlet pressures 4 psi. Total labor: 75 minutes/month! What about diffusion screens? “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.”

The benefits The APF Cleaning Protocol and I 2 Air Infused mixed media; Increases system efficiency. Effectively removes bio-film and minerals. Eliminates exchanger breakdown. Prevents the reformation of bio-films. Does not use caustic chemicals. Uses very low dose iodine. Does not allow exchanger cleaner into groundwater or well System down time is under 2 hours per month. Low cost of use. Does not expose staff and environment to bio-films and dangerous chemicals. Environmentally friendly.
