9. Traitement des microbes par encapsulation This process has a significant dis-infection effect against microbes, carried out in two ways. First, the microbes are actually suspended particles, so free of their surface charge, they become attractive surfaces for the minerals coming out of solution. They are encapsulated in the forming powder…not killed, but rendered unable to reproduce. Second, as they flow through the Dolphin, the Pulsed signal repeatedly “zaps” them, weakening not killing them. They are unable to sustain a vigorous population. They are carried out in the powder and die in 24-48 hours.This process has a significant dis-infection effect against microbes, carried out in two ways.

11. Le PEM contrôle toutes les espèces de bactéries qui sont présentes Les biocides ne sont pas efficaces contre toutes les espèces de bactéries Les bactéries ne forment pas de résistance au Dolphin Les bactéries crées une résistance aux biocides (plusieurs biocides doivent êtres utilisés en alternance) Avantages du contrôle physiqueVS chimique des bactéries

12. Les garanties

13. Basis of our guarantee is the CTI recommendation of 10,000 CFUs Five seasons of data at Alcoa. A variety of load conditions over the course of the year. Wet shutdown over winter – circulate the water for a few hours when outdoor temperature allowed (heated basin). Some fluctuations when system was started up at beginning of cooling season Consistent control of microbial Basis of our guarantee is the CTI recommendation of 10,000 CFUs Five seasons of data at Alcoa.

14. Two towers tested and studied by Quinipiac University – one system on chemical control and the other with Dolphin. Chem system eventually changed to Dolphin Can see where the system was shocked with chemical additions to control bacteria at $5000/yr/tower Bacteria will become resistant to biocides which results in having to change biocides with chemical treatment One excursion after changeover to Dolphin due to biofilm dying off and releasing bacteria Excellent ongoing control with DolphinTwo towers tested and studied by Quinipiac University – one system on chemical control and the other with Dolphin.

15. Legionella bacteria are present in most water Different people are more or less susceptible to legionella Many studies have concluded that to have a legionella outbreak, three things must occur Must have legionella present and ir be allowed to amplify It must get into the air as a mist and be breathed Usually sick people more susceptible such as in hospitals Need to keep the tower and drift away from air intake Legionella bacteria are present in most water Different people are more or less susceptible to legionella Many studies have concluded that to have a legionella outbreak, three things must occur Must have legionella present and ir be allowed to amplify It must get into the air as a mist and be breathed Usually sick people more susceptible such as in hospitals Need to keep the tower and drift away from air intake

16. Dolphin treatment has excellent biological control which results in no biofilm thus eliminating the amplification potential No amplification is the best protection from LegionellaDolphin treatment has excellent biological control which results in no biofilm thus eliminating the amplification potential No amplification is the best protection from Legionella

17. Contrôle du biofilm par le PEM Méthode de contrôle par épuisement des nutriments Préviens la maturation du biofilm Carence en nutriments du biofilm mature Confirmation du contrôle du biofilm Pas de biofilm au touché Compte bactériologique bas Pas de biofilm dans les tours d’eau traitées par le PEM

18. Transfer de chaleur – 4 fois plus isolant que du tartre et particulièrement mauvais pour les tubes des échangeurs Encrassement de l’alimentation – Biofilm trappe les saletés et les débris dans le rampe de pulvérisation réduisant l’efficacité de la tour d’eau. Corrosion – Corrosion induite par biofilm Pathogènes – Contrôle de la Légionelle accomplie par le contrôle du biofilm. Problèmes causés par le biofilm

29. Corrosion Deux catégories de corrosion: Corrosion uniforme Corrosion localisée

30. Dolphin forces system into alkaline mode at the saturation point of Calcium Carbonate which is a cathodic corrosion inhibitor so low uniform corrosion No need for corrosion inhibitors Dolphin forces system into alkaline mode at the saturation point of Calcium Carbonate which is a cathodic corrosion inhibitor so low uniform corrosion No need for corrosion inhibitors

31. Corrosion uniforme

32. Corrosion localisée Les types de corrosions localisées qui écourte la vie des équipements: Corrosion induite par les microbes (MIC) Piqûres par les chlorures Corrosion induite par les produits chimiques Elles ne peuvent pas êtres mesuré ou prévu et sont habituellement détectées trop tard
