This becomes a daunting task due to the variability of the complex geochemical and microbiological underground environment, and the reliance of the user to perfectly design a specific chemical combination required to fully remove the plugging&#8211;while not effecting well construction.<\/p>\n<h4><span style=\"color: #e04b4b;\">Well Rehabilitation and Maintenance with Aqua Freed<span style=\"font-size: 8pt;\">\u00ae <\/span>and Aqua Gard<span style=\"font-size: 8pt;\">\u00ae<\/span><\/span><\/h4>\n<blockquote><p>Since 1988, the Aqua Freed<span style=\"font-size: 8pt;\">\u00ae<\/span> water well rehabilitation process has been used on thousands of wells worldwide with excellent results.<\/p><\/blockquote>\n<p>The Aqua Freed process uses gaseous and liquid carbon dioxide to restore water wells. Aqua Freed is broad ranging in its ability to effectively disrupt and remove a wide variety of plugging deposits, in many different types of wells. It offers superior deposit removal and more complete pore volume recovery, with adversely effecting well construction.<\/p>\n<p>The process has been used on a wide variety of wells including vertical wells, horizontal well, extraction wells, from shallow to very deep wells, from small diameter to large diameter, screened and open hole. Many of the wells treated have been rock open-hole wells that do not have a well screen, but are completed in fractured formations of limestone, dolomite, granite, and sandstone.<\/p>\n<p><a href=\"http:\/\/wrswater.com\/wp-content\/uploads\/2015\/07\/afimage.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-80 size-large\" src=\"http:\/\/wrswater.com\/wp-content\/uploads\/2015\/07\/afimage-1024x311.png\" alt=\"Aqua Freed Before and After Treatment | Water Recovery Services, Inc.\" width=\"1024\" height=\"311\" srcset=\"https:\/\/wrswater.com\/wp-content\/uploads\/2015\/07\/afimage-1024x311.png 1024w, https:\/\/wrswater.com\/wp-content\/uploads\/2015\/07\/afimage-300x91.png 300w, https:\/\/wrswater.com\/wp-content\/uploads\/2015\/07\/afimage.png 1140w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a>The Aqua Freed process is more effective at removing both deposits from inside the well screen and the formation surrounding the well. One of the active components from the injected gas is carbonic acid, a mild acid, which under atmospheric conditions produces a pH of +\/-6.0.\u00a0 However, there is pressure in an aquifer or a sealed well, allowing the pH values to become reduced to as low as 5.0. (still relatively mild). When the pressure is released, the pH will return above pH 6.0; therefore it does not become a neutralization or disposal concern. There is also the effect of localized freezing, and more importantly, agitation, as the liquid carbon dioxide is injected at approximately 0\u00b0F.<\/p>\n<p><a href=\"http:\/\/wrswater.com\/wp-content\/uploads\/2015\/07\/step_2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-96 size-thumbnail\" src=\"http:\/\/wrswater.com\/wp-content\/uploads\/2015\/07\/step_2-150x150.jpg\" alt=\"Aqua Freed Step 2 | Water Recovery Services, Inc.\" width=\"150\" height=\"150\" \/><\/a>Aqua Freed&#8217;s success is achieved from a combination of carbonic acid, agitation, and localized freezing, which results in superior disruption and detachment of the encrusted and plugging material.\u00a0The bulk of the activity is due to phase changes. The expansion rate from a liquid to a gaseous state of the carbon dioxide is 570 times in volume.\u00a0 The agitation achieved with liquid carbon dioxide is the same action as when dry ice is placed in water.\u00a0 There is agitation as the carbon dioxide changes, in this case, from a solid to a gaseous state.<\/p>\n<p>The Aqua Freed process is the controlled injection of carbon dioxide. The rate and volume of carbon dioxide injected is regulated to assure that the pressures (and energy) going down the well can dissipate into the surrounding formations.
