Stir it up: Five tips for more effective industrial aeration
We all know that aeration is a simple but versatile secondary treatment, with uses ranging from removing gases and dangerous compounds from wastewater, to encouraging the action of microbes as they break down solids. If you’re using aeration in an industrial setting, you may be producing streams with concentrations of biological oxygen demand (BOD), chemical oxygen demand (COD), and ...

Aerators Enhance Aerobic Digestion Process
The city of Eden,N.C.,operates an extended aeration process designed for an average flow rate of 13.5 mgd with a mixed liquor suspended solids concentration that typically checks in about 6,000 mg/l. This high biomass concentration is necessary to provide a well-settling sludge and good effluent quality. Further, the plant influent is approximately 40% domestic wastewater and 60% industrial ...

Performance of Floating Horizontal Aerators in Aerated Lagoons and Oxidation Ditches
INTRODUCTION When selecting aeration equipment to use for a specific application, issues to address include reliability, serviceability, capital cost, system appurtenances, and cost of operation and maintenance. Another important consideration is oxygen transfer rate (OTR). Horizontal floating aerators have relatively high transfer rates and have been used successfully in aerated lagoons and ...

Produced-water Recycling and Energy Reduction for Central Oklahoma
Enhanced oil and gas recovery (fracturing) techniques and water go hand in hand. Current pressures including limited fresh water sources, transportation, fracturing volume requirements, and disposal costs and restrictions are driving the development of new water management strategies. Recycling and managed biologic treatment of surface water is proving to be a cost-effective, more environmentally ...

Get Custom THM Stripping Without Breaking the Bank
To limit costs, consider site-specific parameters if installing off-the-shelf trihalomethane removal systems. DISINFECTION by-product (DBP) regulatory compliance requires public water systems to achieve total trihalomethane (TTHM) levels of 80 ug/L (ppb) or less for a locational running annual average throughout a community. Often a water treatment plant's most cost-effective approach is to ...

Coca-Cola Refreshments Bottling Company Needham Heights, MA case study
The Problem: The Coca-Cola Bottling Company was operating an MBR system that was not performing to maintain the flow rate required for effluent discharge. The Membrane System had rapid flux decline and the tubular membranes were being replaced every 6 months. The Solution: BioprocessH2O supplied a bioFLOW MBR System sized and designed to reduce BOD using a bioFLOW Membrane System combined with a ...

Oxygen, the fix for pond problems
Aeration of a water feature should have three main considerations. These include preventing thermal stratification, balancing the dissolved oxygen levels throughout the water column from the sludge or benthic layer to the surface and balancing temperature levels throughout the water column. Although oxygen transfer from certain methods may be significant, the greatest amount of oxygenation takes ...

Wastewater lagoons – a new aeration concept
The use of wastewater treatment lagoons, or stabilization ponds, is a common practice for rural municipalities and industrial facilities. Through the years there have been numerous designs for these ‘sludge settling basins,’ ranging from facultative, partial aerated, and fully aerated systems. But the primary reason for these systems is to utilize relatively shallow earthen ponds, or ...

Aerator materials matter
Stainless steel construction means durability and longevity of your aeration equipment in even the toughest environments Aerators need to be made from durable materials for longevity and reliability in harsh environments. That’s why Fluence aerators come with rugged, all-stainless steel options. Our seven aerator lines, led by the flagship TORNADO and HURRICANE, are manufactured in the ...

Sequencing batch reactor
Sequencing batch reactors (SBR) sequential batch reactors are industrial processing tanks for the treatment of wastewater. SBR reactors treat waste water such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the waste water to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to make suitable for ...

Controlling Aeration Bioaerosols
Aeration of wastewater can cause pathogens to go airborne, but the right choice of aerator can minimize the danger During wastewater treatment, an adequate disinfection stage kills virtually all bacteria and viruses that might be harmful the public, agriculture, and ecosystems before effluent is discharged or reused. But disinfection is generally the final stage of treatment, so when wastewater ...

Robust Systems for Optimal Treatment - Big-Park – Case Study
Overview Big Park Domestic Wastewater Improvement District in Arizona had constructed a new 500,000 gallons per day biological wastewater treatment system in 1997. As time passed, the aging plant was unable to keep up with increasing demands. Challenges In 2012, the District started working with Sunrise Engineering to find a solution that would work in their existing plant. Sunrise Engineering ...

The Climb To The Top
Back in the late 1980’s when market drivers created the cost-effective option of using above-ground circular tanks for industrial activated sludge processes, there were some early valuable lessons for both aeration equipment manufacturers and plant operators. As production plants got away from in-ground basins, one of the more simple innate operational checks became more challenging; that ...
