High VolumeFloating Aerator

The DO2E Patent High Volume Floating Aerator / Mixers are high-efficiency all welded, heavy-duty PVC devices. These state-of -the- aerators are designed to pull water from significant depths for aeration and mixing. On-site sludge digestion is greatly enhanced by drawing dormant sludge deposits off the bottom of the lagoon and inject-ing them with heavy concentrations of dissolved oxygen. By operating with low-pressure (>2.5 P.S.I.) high-volume ambient airflow, these devices maxi-mize oxygen transfer and energy efficiency. These units are scalable, multi voltage and can be modi-fied to fit virtually any aeration and mixing applica-tion.

DO2E utilizes the latest “Green Technology” and continues to set the standards in the Aera-tion industry. Our products are designed to be as maintenance-free as possible. Constructed from

100% heavy-duty marine grade PVC, allows our units to withstand extreme temperatures and harsh environments encountered in virtually every waste-water application. In most installations, Our clients have realized, enhanced worker safety, mainte-nance cost reductions up to 95%, and energy sav-ings of up to 80%. Our product line is the most energy efficient, maintenance friendly, and cost effective product introduced to the waste water market in the past 40 years.

Worker Safety is greatly enhanced by virtu-ally eliminating man entry into the lagoon. Since there are no moving parts to wear out, and the fact that it is secured in place by mooring ropes, there is no need for man entry into the lagoon. Since the blowers are land based, operate at low pressure ambient temperature, and the power can be turned off and locked-out at the blower location, workers

s

safety is further enhanced. The DO2E aerators were specifically designed for: worker’s safety, high oxygen transfer, high water volume move-ment, energy efficiency, and reduction in main-tenance cost. Air supply is provided to each aerator via regenerative air blower placed at a remote location on land for easy access. With no electricity in or around the water and no mov-ing parts, DO2E greatly reduces the worker’s exposure to risks associated with old and out-dated aeration equipment used today. DO2E has designed and patented the safest and most environmentally friendly aerator / mixer on the market.

A unique feature of the Aerator system is its’ expandable capability for the delivery of various gaseous materials such as ozone, hybrid ozone with hydroxyl radicals, carbon dioxide, pure oxygen or other gases required to remedi-ate various issues. This delivery method allows us to inject directly into the wastewater stream allowing for an effective and cost efficient means of direct treatment in order to address various issues such as on-site sludge digestion, and odor control.

All units are designed to address various issues where aeration is required. The primary tasks and functions of the aerators/mixers are to aerate and destratify the water column with minimum energy consumption. Other tasks are

completed simultaneously including drawing from various water depths, breaking up sludge deposit into smaller particulates, de-stratifying the water column, producing high levels of dis-solved oxygen and depositing solids into specif-ic zones or areas. “Ozone”, one of the strongest oxidants readily available can be added to the units to address both recalcitrant particulates and noxious microorganisms, including a wide variety of pathogens. “Ozone” also causes the oxidation of sulfides for enhanced odor-control.

All DO2E Aerators draw water into the device by means of the Venturi effect with no bottom scoring or no negative affects to lagoon liners. Water is then expelled through the upper chambers. This process creates a vacuuming effect drawing sludge deposits into the process chamber where they are injected with high levels of oxygen or in some cases, ozone. This process greatly accelerates the digestion of heavy sludge deposits that are sitting dormant on the bottom of the pond or lagoon. Our pat-ented aeration tubes are designed to deliver a unique combination of coarse, medium, and fine bubbles which when released at a specific depth, draws the water in through the bottom of the unit. Water is pulled upward being aerated all the while and redirected into a horizontal flow across the highly oxygenated upper portion of the water column.

The Patented High Volume State of the Art Aerator injects high volume, low-pressure air through a specially designed multi chambered air manifold located at the bottom of the unit. This unit creates a surface current up to 3 knots for a distance of up to 100 ft. Using a unique combination of coarse air and fine air bubble aeration, we are able to move high volumes of water (up to 24.1 million gallons per day), while at the same time transferring high volumes of dissolved oxygen throughout the water column. The fine air bubbles maximize the oxygen transfer while the coarse air bubbles provide the ultimate velocity. The unique combination of coarse and fine air bubbles released at a specific water depth within a confined space allows for a highly efficient aeration and mixing. The unit can operate in as little as 4’ of water and can draw from depths of up to 16’ of water.
