RW Solutions, LLC

A Division of DO2E WasteWater Treatment

The High Volume Floating Aerator / Mixers are high-efficiency all welded, heavy-duty PVC devices that are unique in several ways. Our patented products are designed to pull water from significant depths for aeration and mixing. By operating with low-pressure (<1.85 P.S.I.) high-volume airflow, these devices maximize energy efficiency. Our patented products are scalable and multi voltage.

The High Volume Floating Aerator utilizes the latest “Green Technology” and continues to set the standards in the Aeration industry. Our products are designed to be as maintenance-free as possible. Construction from 100% heavy-duty PVC, allows our units to withstand harsh environments encountered in virtually every wastewater 

application. In most installations, DO2E’s clients have realized maintenance cost reductions up to 95%. Our product line is the most energy efficient, maintenance friendly, and cost effective product introduced to the waste water market over the past 30 years.

From a safety standpoint, our High Volume Floating Aerators reduces employees’ exposure to risks by utilizing two key components: land based blowers and no moving parts. Air supply is provided from a regenerative air blower placed at a remote location on land for easy access. With no electricity in or around the water and no moving parts, we can greatly reduces the worker’s exposure to risks associated with standard aeration equipment used today. We have designed and patented the safest and environmentally friendly aerator / mixer on the market.

A unique feature of the High Volume Floating Aerator system is its’ expandable capability for the delivery of various gaseous materials such as ozone, hybrid ozone with hydroxyl radicals, carbon dioxide, carbon monoxide, or other gases required to remediate various issues. This delivery method allows us to inject directly into the wastewater stream allowing for an effective and cost efficient means in order to address various issues, for example, hydrogen sulfide before it is released into the atmosphere.

All RW Solutions units are designed to handle several different tasks. The primary tasks and functions of the aerators/mixers are to aerate and mix the water column and distribute it from the device. Other tasks may be completed simultaneously including drawing from deep sludge deposits, breaking up sludge deposit solids into smaller particulates, de-stratifying the water column, and aerating and/or depositing solids into designated locales. ”Ozone” 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.

Aerators can be designed to address a variety of environmental issues. This is accomplished by increasing the horsepower of the blowers used, increasing the aeration rate by the manipulation of the bubble mixture, changing the physical size of the aeration module, utilizing the type and viscosity of the material encountered in both the water and air column.

All the High Volume Floating Aerators draw water into the device by means of the Venturi effect. Water is then expelled through the upper chambers. Our patented 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 that is perpendicular to the input of the water column.

A resonance circulation of the water column, allows the devices to increase the unit’s “pull” from the water column. Depending on the amount of force generated from the initial airstream (which is a multivariate function of power horsepower of the blower), the temperature of the water column, and the viscosity of the water column. The “reach” of the aerator can be as deep as 18’ from the surface of the water. Depending on varying conditions, it may take different times for equilibrium to be reached so that a consistent draw from depth results. By injecting cool ambient air in combination with the air pressure and water pressure released within a confined space, insures that the RW Solutions aerator achieves maximum oxygen transfer.
