and Seeing Nanobubbles"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">by John Huizenga<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this experiment with <a href=\"https:\/\/www.oxidationtech.com\/applications\/water-treatment\/ozone-nanobubbles.html\">nanobubble<\/a> generating equipment we will use a simple green laser to evaluate several methods of generating nanobubbles.\u00a0\u00a0 A green laser light is an excellent method of determining the presence of <a href=\"https:\/\/www.oxidationtech.com\/ozone\/ozone-basics\/ozone-nanobubble-review.html\">nanobubbles in water<\/a> and a general idea of more nanobubbles or less <a href=\"https:\/\/www.oxidationtech.com\/ozone\/ozone-basics\/ozone-nanobubble-review.html\">nanobubbles<\/a> when compared to a similar sample.\u00a0 When a green laser beam shines through water, the laser light reflects off the microscopic bubbles, and you are able to see the beam natively with no additional equipment needed.\u00a0 This phenomenon is similar to effect of a beam of sunlight shines through a dusty room<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Principles of analysis:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A visibly brighter beam indicates a higher concentration of nanobubbles or nanoparticles in the water.<\/li>\n\n\n\n<li>Duration of nanobubble presence confirms bubbles that do not float to the surface.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The photo below demonstrates the first principle.&nbsp; With a green laser beam shining through two water samples, the faint beam appearing in the left sample indicates a low concentration of nanoparticles, and the bright beam on the right sample indicates a high concentration of nanoparticles.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><a

reflecting off tiny particles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Equipment used to generate nanobubbles for the first test:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1hp pump circulating water for 1 minute from a stainless steel tank with 5 gallons of tap water through a <a href=\"https:\/\/www.oxidationtech.com\/products\/accessories\/ozone-injection\/static-mixer.html\"><strong>static mixer<\/strong><\/a> with 3 LPM oxygen\/ozone injected at the pump outlet several inches ahead of the static mixer.\u00a0<\/li>\n\n\n\n<li>1hp pump circulating water for 1 minute from a stainless steel tank with 5 gallons of tap\u00a0 water through an <strong>electrocoagulation and cavitation<\/strong> nanobubble device\u00a0with 3 LPM oxygen\/ozone injected at the pump outlet several inches ahead of the static mixer.\u00a0<\/li>\n\n\n\n<li>1hp pump circulating 5 gallons of tap water for 1 minute\u00a0 through the Oxidation Technologies <a href=\"https:\/\/www.oxidationtech.com\/ost-skid.html\"><strong>OST injection skid<\/strong><\/a> tank using a Mazzei 784 venturi \u00a0with 3 LPM oxygen\/ozone injected venturi suction port.\u00a0 Water loop under 30 psi of pressure.\u00a0<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">At the end of the treatment, water samples were drawn off and an hour later the green laser was used on each sample.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As you can see in the picture below, the laser beam test suggested a high concentration of nanobubbles for all of the samples and the results were not very helpful in verifying the presence of nanobubbles.&nbsp; The problem is that tap water contains many nanoparticles that reflect the laser beam.&nbsp; Reverse osmosis water removes most of these particles so we use reverse osmosis water instead of tap water in the next test.&nbsp;<\/p>\n\n\n\n<figure
