The ADS Advantage

Over the last 60 years, Air Diffusion Systems (ADS) fine bubble aeration has been installed around the world to promote natural and biological treatment of lakes, lagoons, reservoirs, and other bodies of water.  Bubbling from the bottom up, ADS diffusers recreate a river-like environment in bodies of water that lack oxygenation and mixing.  Once elevated “bottom dissolved oxygen” levels are restored, settled microbes, and higher life forms consume organics and nutrients. The final result is a clog-free diffuser that is efficient as it is effective.

Not all Bubbles are Created Equal

There is a significant difference in the way larger "coarse" bubbles and smaller "fine" bubbles mix and oxygenate water. Fine bubbles need less energy to create and provide a larger surface area for oxygen transfer to occur.  Coarse bubbles larger than 1/10” diameter are limited in their mixing capabilities due to the turbulent manner in which they move through water. The same amount of energy is required to produce a single 1” coarse bubble or a million 1/100” fine bubbles. ADS fine bubble aeration ranges from 1/8” to 1/64” in diameter, providing efficient quiescent mixing and unsurpassed oxygenation.

Independently Certified Using “ASCE” Oxygen Transfer Standards

ADS fine bubble aeration offers a superior oxygen transfer rate, which was independently tested and certified by former federal EPA Advisor, Dr. Michael Stenstrom. Three sets of tests were performed according to the testing procedures and standards developed by the American Society of Civil Engineers (ASCE). These independently verified results concluded that ADS fine bubble aeration delivers an oxygen transfer rate of ~ 3% per foot of water Standard Oxygen Transfer Efficiency (SOTE). This is twice as efficient compared with other diffusers and four to six times more efficient compared with static tubes, jet, or surface aerators.

ADS Fine Bubble Diffusers & Aeration

ADS fine bubble diffusers & aeration tubing is manufactured using virgin plastics containing more than 2% “carbon black” to prevent UV degradation. The aeration tubing contains microscopic air-releases located along the top and sides where the fine bubble are emitted. If the air supply is shut off, the air-releases act as a one-way check valve, preventing plugging or clogging of the aeration system. One of the key design features of ADS aeration is the built-in pressure drop. The 2 PSI pressure drop ensures that the fine bubble diffuser will work even if the bottom is not perfectly level.

ADS Fine Bubble Diffuser Treatments

Wastewater Aeration Treatment

For more than 60 years, ADS has specialized in the biological treatment of domestic and industrial wastewater. We are committed to providing our clients with the highest cost benefit, utilizing the most innovative treatment technologies available. ADS fine bubble diffusers are designed to meet or exceed all permitted effluent requirements and treatment goals. With hundreds of installed systems, ADS is proud to offer an industry leading 5-year product and treatment guarantee.

Lagoon Aeration Treatment

Lagoon aeration is our specialty.  The ADS aerated-facultative lagoon approach provides the highest cost-benefit and reliability of any fine bubble aeration system commercially available.  A properly designed ADS system is 3 to 6 times more efficient than high-speed surface aeration or static tubes, and 2 to 4 times more efficient than other diffused aeration systems.  By using highly efficient blowers, operational costs are typically less than $0.01 per capita/day.  The energy savings alone can help to pay for the system within several years of operation.  Because there is only one moving part (the blower), operation and maintenance is very easy.

Sludge Reducing Bacteria (SRB)

Sludge accumulation is one of the most significant issues at wastewater treatment facilities small and large.  Disposal and physical removal of stored organics and sludge can be a tricky and costly proposition.   ADS Sludge Reducing Bacteria (SRB) offers proven results for reducing accumulated bottom sludge and sediments at a fraction of the cost compared with physical removal.

Lake Aeration Treatment

Without natural or artificial circulation, lake and reservoir water goes through a process of aging called eutrophication in which inorganic & organic materials accumulate at the bottom.  This accumulation depletes bottom oxygen levels creating anaerobic conditions that cause many long-term problems for lakes and reservoirs. ADS fine bubble aeration restores oxygen throughout the entire water column, revitalizing water the natural way.

Harmful Algal Blooms Treatment

Harmful Algal Blooms (HAB’s) are a major environmental problem around the world.  Also known as cyanobacteria or blue-green algae, HAB’s can reproduce very quickly in warmer water where excessive nutrients are prevalent.  In addition to depleting oxygen and producing toxins, HAB’s can adversely affect taste and odor in public drinking water supplies.  ADS fine bubble diffusers are a proven remedy for minimizing the harmful effects of HAB’s, while also reducing their occurrence.

Tank Aeration Treatment

ADS' fine bubble aeration is an effective method to provide oxygenation and mixing for many types of water storage tanks, including potable water tanks, fracking tanks, industrial wastewater tanks and more. Learn how ADS fine bubble diffusers can help with your above and below ground storage tanks.

Air Sparging (AS) & Fluid Delivery

ADS air sparging (“in situ air stripping”) is very effective in reducing concentrations of volatile organic compounds (VOCs), which are absorbed in soils or dissolved in groundwater. Horizontally drilled piping is the easiest to install and the most cost-effective way to deliver oxygen to the contaminated areas.

Ice Prevention & Ice Melting Aeration

Ice formation can cause structural damage to moored boats, pilings, retaining walls, docks, or entire marinas. ADS ice melting aeration diffusers circulate this slightly warmer bottom water to the surface, melting ice or preventing its formation in the first place.

Aquaculture Aeration

Whether you raise catfish, shrimp, tilapia, prawns, minnows, trout, bass or any other type of aquatic life, there are many benefits obtained by incorporating ADS fine bubble diffusers into your operation including reduced energy costs, increased production, and healthier aquatic and plant life.
