White paper validates modern oxygen switch expertise 

The reservoir testing website.

A brand new, industry-verified white paper validates the oxygen switch effectivity of an modern, fuel infusion expertise for water and wastewater therapy.

The trademarked Dissolved Fuel Infusion (DGI) expertise has been developed by Gas Tech Inc., a US engineering firm, to supply a extremely environment friendly different to present aeration applied sciences to be used in utility and industrial functions. Validation testing reveals DGI delivers higher than 99% switch of oxygen when utilized to a handled physique of water.

Two patent-pending applied sciences are utilized in mixture to make sure optimum and exact fuel supply to focus on water and wastewater processes. These embrace a subsequent technology, pressurized saturator for fuel switch of the oxygen resolution to a slipstream of water; and an modern nozzle supply system to distribute oxygenated water that just about eliminates fuel loss from a focused physique of water.

The trademarked DGI expertise was examined utilizing validation methodologies printed by the American Society of Civil Engineers (ASCE) and its Environmental & Waters Analysis Institute (EWRI). The outcomes of the checks, which have been peer-reviewed and endorsed by {industry} specialists, have decided that:

  • 99+% of the oxygen equipped to the DGI system was delivered to a therapy reservoir as dissolved oxygen with no loss to the environment, inside described measurements of uncertainties.
  • The DGI channel injector successfully transferred the oxygen-infused water stream to reservoir water whereas positioned solely twenty-four inches under the water floor.
  • There was no measurable lack of oxygen to the surroundings, no seen bubbles, and no delay within the availability of the equipped oxygen to react within the aqueous part.

DGI combines market-leading oxygen switch effectivity with precision accuracy to ship an vitality environment friendly and cost-effective water and wastewater therapy system. This cutting-edge expertise achieves its 99+% fuel switch charge by pre-dissolving excessive purity fuel in a separate pressurized slipstream.

The oxygen infused slipstream can attain as much as 900mg/l oxygen focus, which is then added to the primary physique of water and diluted to satisfy exact buyer specs. To ensure excessive oxygen saturation charges, DGI is fitted with specifically designed high-velocity channel injectors that assist retain fuel and optimize distribution.

DGI can work as a speedy response choice or increase underperforming legacy applied sciences in a variety of water and wastewater therapy functions throughout completely different sectors, together with municipal utilities, agriculture, surroundings, pulp & paper, meals & beverage, upstream oil & fuel, and landfill administration.

The expertise may help handle a spread of points, together with regulatory compliance, water preservation, organic therapy, odor discount, chemical alternative in wastewater therapy, and enhancing general water high quality for people and the surroundings.

Gas Tech president and chief government officer Vincent Arnone mentioned, “This validation research is a foundational part of the continuing DGI enterprise improvement technique. Gas Tech is on observe to realize the aim of product commercialization in 2023 and has additionally begun recruitment for an skilled water and wastewater therapy government to take DGI to the following stage.”

The DGI expertise, and the end-to-end service offered by Illinois-based Gas Tech Inc., makes use of distinctive computational fluid dynamics modeling capabilities, that are enhanced by internally developed, high-end, visualization software program.
