In 2012, the Town of Francesville in Indiana contacted Air Diffusion Systems to provide a solution for several suspended solids violations and energy efficient treatment. Air Diffusion Systems was able to provide an unique solution to correct biochemical oxygen demand (BOD) and total suspended solids (TSS) problems using Kaeser Compressors’ CB Com-paK blowers.
A carrot packing plant was having severe odor problems due to septic conditions in their truck washout water holding lagoon. In addition, nutrient and nitrogen levels were becoming an issue for land application of the wastewater for crop production.
A leading fruit juice company had expanded over the past ten years and increased wastewater flow from 7,000 to 11,000 gallons per day (gpd), without upgrading its wastewater treatment plant. Read the full case study to learn how after a Mazzei AirJection system was installed, dissolved oxygen levels increased in the aeration basins, which immediately eliminated the odors.
A shopping center in Ventura, CA with several major retail stores, was suffering from a sewer odor problem.
The treated effluent from all wastewater treatment plants across the country must meet local dissolved oxygen (DO) limits before discharging into receiving waters.
The LeSourdsville WWTP in Butler County, Ohio, was required to meet their NPDES permit requirement of 6 mg/l dissolved oxygen at the plants Miami River outfall.
A large vegetable processing facility was experiencing problems with its lagoon surface aerators. The company’s treatment process includes a collection and screening assembly, two anaerobic stabilization ponds and a 40 million gallon aerated lagoon.
A design/build contractor needed a quiet, efficient aeration system for a 250,000 GPD field erected WWTP that was to be located adjacent to a school. A restriction on ambient noise at the location of the proposed WWTP required a quiet aeration process. Read the full case study to discover how Mazzei solved the problem.
Mainsail Global’s Boone diffuser membranes are designed for the petro-chemical market with hydrogenated acrylonitrile-butadiene rubber (HNBR). These custom membranes are built for durability, and can withstand long-term exposure to heat, oil and chemicals readily present in petro-chemical wastewater streams. With excellent tensile strength, abrasion and ozone resistance and higher modulus retention at elevated temperatures, Boone membranes combine the physical strength and chemical makeup of HNBR for an ideal solution in petro-chemical wastewater treatment.
The Wet Well Wizard is the only ‘one-size-fits-all’ wet well aeration system that has no moving parts, is completely non-corrosive, is simple to install, and utilizes no electricity underwater. It can be installed in 30 minutes and requires almost no maintenance.
Our fine-pore, flexible diffusers can reduce facility energy costs by up to 40%. No matter your industry, your custom, chemically-correct solution is built to last and save you money.
The Com-paK is uniquely designed to minimize space requirements and reduce installation costs.
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.
Aqua-Jet® aerators are installed in a wide variety of wastewater treatment schemes including activated sludge systems such as SBRs, MSBRs and extended aeration, as well as aerobic digesters, sludge holding, and equalization basins. It is also UL approved for TTHM stripping in potable water applications.
Discussing the projects that RWL Water has been involved with in 2016, you understand just how variable the world of water treatment really is.
When it comes to wastewater lagoons, there are three main challenges that operators run into. The first, similar to other parts of the nation’s wastewater treatment infrastructure, is age. The second is compliance with new EPA ammonia, nitrogen and phosphorus limits which many lagoon plants weren’t designed to deal with. And the third is expansion as communities grow and need additional capacity.
At WEFTEC 2016, Evoqua Water Technologies explored six core challenges faced by wastewater treatment plants -- energy reduction, nutrient removal, odor and corrosion control, aging plant equipment, water reuse and disinfection. In this Water Online Radio interview, Paul Rice, Municipal Marketing Director with Evoqua Water Technologies, discusses energy reduction and nutrient removal in more detail.
At the wastewater treatment facility, the biggest energy consumer is almost always the multistage aeration blowers. Replacing these blowers with high speed turbo blowers can save energy but the short-term cost to replace the existing blowers, reroute pipe and set new foundations can make the change a hard sell.
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.
Find out the importance of total cost of ownership in wastewater treatment applications and how Atlas Copco supports this approach.
Fluence’s Membrane Aerated Biofilm Reactor (MABR) technology is an innovative wastewater treatment solution which saves up to 90 percent energy consumption. It is the ideal solution for decentralized applications such as rural villages, housing developments, municipalities, hotels, resorts, and golf courses.
Surrounded by agricultural fields where water is a vital resource, the rural region of Hayogev, Israel chose Fluence’s energy-efficient Membrane Aerated Biofilm Reactor (MABR) solution for wastewater treatment suitable for reuse.
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.
