WASTEWATER AERATION & BLOWERS WHITE PAPERS AND CASE STUDIES

Albertville WWTP Uses Biogas Blower To Replace Natural Gas To Fuel Boilers

As part of an ongoing effort to improve efficiency and lifecycle costs across all of its projects, a Municipal Utilities Board in Albertville, Ala., set out to upgrade solids handling at the WWTP and pursue Class A biosolids certification, a U.S. Environmental Protection Agency (EPA) designation for dewatered and heated sludge that contains low levels of pathogens.

Submersible Aerators Blast Off At Naval Air Station WWTP

When the Jacksonville, Florida Naval Air Station needed to increase oxygen in their aeration basins, they turned to RWL Water. Five submersible HURRICANE aerators provide bottom-up mixing, drawing surface air and dispersing it in a 360-degree pattern near the basin floor. Long bubble hang time results in excellent oxygen transfer, and ensures excellent BOD and ammonia removal, treating flows up to 3 MGD.

1600 Series For Fats, Oils, Greases, Phosphorus, Chlorines and Other Chemicals

1600 Series For Fats, Oils, Greases, Phosphorus, Chlorines and Other Chemicals

Designed with the dairy market in mind, the Dampier membrane is optimized to withstand long-term exposure to fats, oils, greases, phosphorus, chlorines and other readily present chemicals. Its silicone elastomers possess inherently low intermolecular forces, providing excellent resistance to hot and cold temperatures. Our Dampier membranes are hydrophobic, and do not react with the unique chemicals present in dairy wastewater. Heat stable (up to 365°F) and flexible at low temperatures, these custom formulated membranes provide durable, chemically-correct solutions for dairy wastewater treatment.

Traffic Rated Screen Drain Grates

Traffic Rated Screen Drain Grates

Most lift stations and basins require separate drain inlets that do little to keep out large solids such as gravel, branches and general litter than can destroy pumps. ClearBlu has developed a traffic rated grate system that utilizes perforated plate with 1/4″ holes. The grate sits in a heavy grate frame that embeds in concrete. By embedding the frame in concrete, traffic weight is carried by the frame and concrete and not the basin. This allows the basin to be secured and sealed to a poly or fiberglass basin.

ABOUT AERATION

 

A common first step in the secondary treatment process is to send wastewater to an aeration tank. In an aeration tank, bacterium is used to effectively break down pollutants into less harmful components. Wastewater aeration provides the appropriate oxygen level so that aerobic bacteria can thrive in degrading pollutants such as iron and manganese as part of the wastewater treatment process. Aeration can also be used to destroy anaerobic bacteria that perish in the presence of oxygen. Aerobes that can break down pollutants 10-100 times faster than anaerobes are used most frequently.

Aeration is also used to improve waste lagoons and other waterways such as lakes and reservoirs where oxygen deficiency contributes to taste, odor and pollutant problems. Equipment used for wastewater aeration includes low cascades, jet fountains, spray nozzles, blowers, submerged perforated pipe and porous plates or tubes. Whether the water is thrown into the air via a fountain or diffused by air bubbles being blown or drawn into the wastewater in an aeration tank, aeration works by increasing the area of contact between the oxygen in the air and water.

The most common wastewater aeration process in use today is the air diffusion process, where air is introduced from blowers through diffusion tubes suspended in a spiral flow tank, or in some cases, through diffuser plates in the bottom of the aeration tanks.
