the use of a vertically designed Degasification tower. A Decarbonation tower is specifically designed to remove Carbon Dioxide (CO2) from a water treatment process. When the water is being treated for “potable” use for direct or indirect consumption than all of the components used in the process must comply with NSF/ANSI 61 standard to assure that the components that have direct contact with the water are safe and will not introduce any foreign substance during the treatment process. Decarbonation towers have direct exposure and contact with the water during the removal of CO2 and therefore must be manufactured from material such as Fiberglass (FRP) that complies and meets the NSF/ANSI 61 standard.

requires the use of certified FRP resins and protocols during the fabrication process of the Decarbonation tower. It is normal protocol at DeLoach Industries Inc. to install a veil lining inside of a Decarbonator or Degasification tower that complies with NSF/ANSI 61 standards to safeguard all potable water projects. Decarbonators are utilized in the food and beverage industry, municipal industry, pisciculture, semiconductor industry, and other industrial markets. In addition to the Decarbonator complying with the NSF/ANSI 61 standard it is equally important that the fiberglass (FRP) tanks also comply with the same standard and follow the same protocols during the manufacturing process. The NSF/ANSI 61 standard was developed to safeguard the public and provide assurances that water is free from impurities.

both too and from the process must also comply with the NSF/ANSI 61 standard. Because the US imports so much of its raw materials and also finished goods from outside the US the NSF/ANSI 61 standard has been adopted as an internationally accepted standard for other non USA manufacturing companies to follow. Water piping conveyance and delivery systems can be manufactured from a variety of materials such as stainless steel, carbon steel, lined carbon steel, PVC, and fiberglass (FRP). Each material when used for the manufacturing of potable water conveyance piping and fittings must follow the strict protocols and standards set forth by the NSF/ANSI 61 guidelines.

When reviewing a design of a Decarbonation or Degasification system it is important to analyze both the shell structure as well as all internal items that will have direct contact with the water that is being treated. It is the responsibility of the Original Equipment Manufacturer (OEM) to safeguard their products during the fabrication process by reviewing and selecting suppliers who also meet and comply with the NSF/ANSI 61 standards. At DeLoach Industries Inc., there are detailed reviews of all raw materials before they are utilized in the fabrication of their water treatment systems including; Decarbonation, Degasification, Pwater brainressure Filtration, Demineralizers, and Odor Control and Fume Scrubber Systems.

DeLoach Industries is currently designing one of the first “smart” degasification tower utilizing “AI” (Artificial Intelligence) on the market which began being released in 2018 to better serve the water professional industry.
