SANITAIRE Silver Series membrane fine bubble disc diffusers are recognized worldwide for their high oxygen transfer efficiency and durability in wastewater treatment plant aeration processes.
Since 1969, Aqua-Aerobic Systems, Inc. has led the industry in surface aeration and mixing with thousands of installed units throughout the world. For those wastewater applications that require an efficient means of introducing oxygen into a system, the OxyMix pure oxygen mixer is an economical solution compared to other pure oxygen devices.
Ten years ago, KLa Systems was presented with the challenge of finding a more wear-resistant material for our jet aeration nozzles. The inner nozzle is the liquid propulsion nozzle of the jet aerator and continuously sees high volumes of motive liquid flow at velocities ranging from 33-46 ft/s. Traditionally, these inner jet nozzles were made from the same FRP material as the outer jet with the industry accepted corrosion/abrasion liner made up of C-Glass/Nexus and Silicon Carbide impregnated into the vinylester resin. For many years this material had held up in most industrial and municipal bioprocesses with no adverse deterioration or wear.
There are many reasons for a utility to rent a blower for wastewater aeration. Besides the obvious — an emergency — plant operators may need a rental to bridge the gap during upgrade projects, supply seasonal need to supplement air, or perform testing.
A combination of urban sprawl, more stringent environmental regulations, and aging facilities is putting a huge strain on the wastewater operations at many municipalities. The good news is that membrane aerated biofilm reactor technology, also known as MABR, offers a compact and energy-efficient solution.
Improving wastewater treatment efficiency requires some type of change in the physics, biology, or economics of the process. In this Water Talk interview, Jeff Kelly, Red Valve’s senior product manager for the Tideflex Aeration and Mixing System, describes how to change all three — to the tune of a cost-saving 50-percent reduction in applied airflow! The Tideflex approach uses a unique diffuser design to support on/off aeration and mixing cycles without clogging. Managed by oxidation-reduction potential (ORP) readings, the novel technique supports a biological selection process that encourages the exclusive growth of facultative anaerobes — the most resilient wastewater microbes, which get rid of phosphates and nitrates without producing hydrogen sulfide.
Population growth, stricter regulations, and increased energy costs continue to exert significant pressure on municipal wastewater operations. But rather than investing in tired, old solutions such as the construction of additional concrete tanks, water system managers are seeking new ways to stretch the limits of their infrastructure.
In 2019, Kaeser Compressors assumed control of the venerable line of PillAerator turbo blowers, strengthening its ability to serve the wastewater industry — or wherever else atmospheric process air is needed on a constant pressure level. Watch this video to understand what inspired the decision, as Manual Dias, Business Development Manager at Kaeser, covers the advantages that turbo blowers offer versus other types of blowers. Al Moreno, Kaeser's District Manager, then highlights the company's screw blower technology, followed by Global Product Manager Peter Werhahn, who provides the business case for investing in turbo blowers.
Long known for serving the wastewater industry with blower and compressor solutions, Aerzen recently branched out to expand its service capabilities with Aerzen Rental USA. With this new, standalone company, Aerzen can now provide its low-pressure, oil-free units for short-term and/or immediate use. In this video, Matt Piedmonte, director for Aerzen Rental USA, cites five situations where a customer might need a rental, and answers some common questions around technology, logistics, and setup/operation. Hint: The company had a head start in mastering these elements, as Aerzen International Rental has been serving Europe for two decades.
Kaeser Compressors' rotary screw blowers offer superior performance, fast installation, low noise operation, and lowest life cycle costs to help wastewater treatment plant operators and designers revolutionize their plant's aeration system.
In this video, Parkson discusses the process of biologically treating wastewater in a batch mode and what differentiates Parkson's SBR from others.
Energy is a huge portion of a wastewater treatment plant’s operating costs, with aeration blowers a significant user. System splitting with an adaptive master controller reduces electrical, maintenance, and initial investment costs.
With a variety of blower combinations available to optimize aeration performance at wastewater treatment plants, efficiencies are now being found by focusing in on aeration control systems. Eric Bennett, Controls Product Manager with Aerzen, recently discussed the advantages operators are finding by deploying the company's AERProcess solution in managing energy use, optimizing biological processes and reducing wear and tear on blowers and valves.
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.
