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. 

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.

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.

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.

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.

Evoqua offers complete anaerobic digestion retrofits designed to address everything from simple repairs and upgrades to complete replacements.

Stable efficiency with magnetic bearings, compact and cost effective installation, and an optimized process by an intuitive compressor control.

S & N Airoflo has supplied floating brush rotors to the municipal and industrial markets for aeration for over 15 years. Our aerators provide very high oxygen transfer and mixing rates to deliver better efficiency with less horsepower, typically achieving 30% to 60% lower energy costs

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.

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.

Evoqua is looking toward the future– and that future is energy-neutral wastewater treatment plants.

With infrastructure dollars still tightly constricted, Aeration Industries International is focusing its attention on making wastewater treatment as cost-effective as possible. “Eighty percent of a wastewater treatment plant’s energy consumption takes place at the aeration basin,” Michael Ramirez, Director of Marketing for Aeration Industries points out in this Water Online radio interview. “Infrastructure dollars are low, everybody knows that. So we need to look for ways to really save money for the customer.”

RWL Water custom-designed and implemented a waste-to-energy solution for Amadori, a leading Italian poultry producer.

RWL Water supplied Tornado aerators as a key part of the engineering solution for a new wastewater treatment plant in the city of Obregon in Northwestern Mexico when wastewater began contaminating groundwater, affecting livestock and causing disease.

Kaeser's blower product manager, Stephen Horne, explains how wastewater treatment facilities can benefit from utilizing blower package and system integration for increased efficiency.

Energy is a huge portion of a wastewater treatment plant's operating costs, with aeration blowers being a major user. System splitting with adaptive control reduces electrical, maintenance, and initial investment costs.

Follow these 5 tips to make sure your compressed air system is ready for winter.

Wastewater aeration is a huge consumer of energy and the leading candidate for cost saving consideration at the wastewater treatment plant.
