VertiCel® Wastewater Treatment Systems

VertiCel® Wastewater Treatment Systems

The VertiCel® system is superior to other aeration technologies because it saves energy and space, while producing an unparalleled effluent quality. It is ideally suited for wastewater treatment plants with process flows above two million gallons per day. The VertiCel® tanks in series design consists of an aerated-anoxic tank followed by an aerobic tank. 

Bi-Directional Jet Aerators

Bi-Directional Jet Aerators

Mass Transfer Systems bi-directional jet aerators are designed with jet aeration nozzles installed on both sides of the liquid/air jet aeration manifold. This configuration is most applicable for square or rectangular tanks, larger lagoons, and sequence batch reactors where directional flow patterns are not desired.
Automatic pH Balancing Systems

Automatic pH Balancing Systems

ClearBlu builds package pH balancing systems for high strength wastewater that are robust and low maintenance.  High strength strength wastewater can easily blind pH sensors, even when they are insertion mounted in a pipe.  ClearBlu utilizes digital self-cleaning immersion sensors for reliability, longer periods between calibration and lower chemical usage.

1500 Series For Cost-conscious Municipal and Industrial Water Markets

1500 Series For Cost-conscious Municipal and Industrial Water Markets

EPDM elastomers’ fully saturated backbone lends these diffusers superb resistance to ozone and oxygen, while its non-polar nature provides resistance to ketones and alcohols. These economical membranes also offer excellent chemical, heat, acid and phosphate fluid resistance. With good low temperature flexibility, this series’ technology provides optimum performance and stability over a broad range of operating temperatures. Our Columbus, Drake and Magellan membrane technology is not recommended for applications where petroleum or mineral oils, or di-ester lubricants are present.

PASSAVANT® Disc Diffuser ROEFLEX®

PASSAVANT® Disc Diffuser ROEFLEX®

The disc diffuser ROEFLEX® stands out for its simple and robust design. It consists of a unique, convex shaped support disc. The disc is covered by a flexible, slotted membrane of elastomer, a ring secures the membrane in place. Due to the disc’s unique convex shape the membrane is slightly lifted off the disc when air is supplied, therefore allowing an even distribution of the generated fine bubbles. The membrane can be delivered in different rubber (EPDM) qualities and slot patterns (HL, SL) according to the application.

The Right Technology To Fit Your Needs

The Right Technology To Fit Your Needs

Aerzen supplies blowers for industrial and for wastewater treatment. Tom McCurdy, Regional Sales Manager at Aerzen, told Water Online radio in an interview that his company is unique in that they have the ability to help customers pick the right technology for the application without bias because they have multiple technologies available. They will work with the customer within what they need in terms of maximum and minimum flows, pressure swings, on-off cycles, etc., and will help guide a customer towards the right technology.

Introducing The O-Factor In Aeration

Introducing The O-Factor In Aeration

There is no one-size-fits-all solution when it comes to aerating wastewater lagoons. As Randy Chann, President and CEO of Environmental Dynamics International (EDI) explains in this Water Online Radio interview, each lagoon environment needs to be configured to meet both financial and regulatory outcomes.

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.
