2. 2. CHC Technology History Developed by Cliff Ashbrook and licensed to Lancer Corporation in the early 1990s. Ballistics observations AW Chesterton licensed the technology from Lancer in 1998. VRTX established as a company in 2003. Liberation Capital invests in VRTX in 2011. EcoWater Systems acquires technology IP in 2014 and renames the business EcoWater CHC.

7. 7. Water & Sewer Savings Average customer reduces make- up water 20% Average customer eliminates 50% of blow-down Because CHC is chemical-free, blow-down may be repurposed for other applications, (i.e. irrigation) saving significantly more water! A Marmon Water/Berkshire Hathaway Company
8. 8. Cavitation Metal Destruction from Uncontrolled Cavitation CAVITATION BUBBLE COLLAPSE cav.i.ta.tionkav' i ta' shunn [1. the rapid formation and collapse of vapor pockets in a flowing liquid in regions of very low pressure. A Marmon Water/Berkshire Hathaway Company Shear stress = 150,000 psi Temperature rise = 10,000 F
9. 9. Inside the CHC Cavitation Chamber The opposing water streams collide in the cavitation zone, causing millions of high energy, micro-sized cavitation bubbles to rapidly form and collapse. This stresses any bacteria and forces calcium carbonate to form in the bulk water. Water from the sump is pumped under high pressure into the cavitation chamber, where it is forced to rotate at high velocity through precision nozzles. The treated water exiting the cavitation chamber is returned to sump where the precipitated calcium carbonate is removed by the integral filtration system.

A Marmon Water/Berkshire Hathaway Company Controlled Hydrodynamic Cavitation Scale Control Changes water chemistry to precipitate calcium carbonate scale Cell Lysing Cavitation kill biologics by breaking down cell walls Corrosion Control Vacuum strips CO2 which elevates pH creating a low corrosion environment
11. 11. Cavitation Zone Chemistry Implications Notes: 1. Chemical treatment tried to keep hardness in solution. CHC removes hardness from the water. 2. Chemicals maintain delicate balance between scale control and corrosion 3. High temperature accelerates CaCO3 precipitation Scale Control Using CHC 1 CO2 Stripping: High-vacuum exceeds partial-pressure of CO2; CO2 is vented 2 Hardness Removed (!): As CO2 vents, reaction shifts right, soft, powdery CaCO3 precipitates and is filtered : Ca(HCO3)2 CaCO3 + H2O + CO2 Dissolved Precipitate Gas (vented) 1. Automatic Scale Controlremoves requirement to maintain delicate chemical equilibrium 2. Cycles of Concentration Increase resulting in less water usage 3. Towers run cleaner resulting in better heat transfer and lower energy usage Notes: 1. With CHC, you cannot over treat.
