New Dif-Jet Gas injector for aeration, Saves Energy and Requires Less Maintenance at Municipal and Industrial Wastewater Plants
Fortrans Inc. manufactures a new line of gas injectors used in aeration systems that require less energy and perform more efficiently over long periods of time.
Fortrans’ patented Dif-Jet ™ gas injectors installed in our patent pending distribution and mixing systems tranfers air into wastewater above the water surface and then pipes the oxygenated wastewater to desired depth where the water is mixed and circulated.water column.
The Dif-Jet™ Gas Injectors are an Aeration Breakthrough
" Dif-Jet™ gas injectors use low pressure blowers
" Dif-Jet™ gas injectors use low pressure blowersto aerate at depth compared to bottom dwelling aerators that require large high pressure blower systems to overcome the pressure at 24 to 30 feet. Most wastewater plants must designed to cope with aerator fouling. So more aerators are installed than are required resulting in huge costs for blower systems. Aeration accounts for 40% to 70% of a typical wastewater plants energy cost. Any energy savings can help the plant reduce their electrical bill.
Aeration capacity upgrades are easy and affordable Supplying sufficient oxygen and high impact mixing to the bacteria is the best way to ensure the wastewater plant avoids bulking and odor problems. With good DO levels, the wastewater plant will not require other chemicals to assist bacterial waste digestion.
The Dif-Jet™ gas injector is non-fouling unlike aeration discs and diffusers located in the bottom of aeration basins. Fine bubble aerators can accumulate biofilm, scale and other contaminants that tend to foul and reduce aeration efficiency.
The performance curve of these fine bubble aerators may form a “bell curve” that reflects operational efficiency. At that point, the aerators must be cleaned either by drawing down the basin or feeding acid through the aerators to clean them. Drawing down an aeration basin at a plant that is treating 5 to 50 million gallons per day may be impossible if there is no storage for incoming wastewater. Flushing acid through the diffusers kills many of the beneficial bacteria that digest the waste. The aeration basin must then be re-seeded with activated sludge containing beneficial bacteria.
These problems are eliminated with the Dif-Jet gas injectors installed in an overhead grid system and down leg piping.
Maintenance is easy to perform with non-fouling non clogging detachable Dif-jet™ Gas injectors and easy to access grid piping and pump.
