How To Select The Most Effective Blower Technology For Wastewater Applications

Given numerous variables when selecting an aeration blower system for wastewater applications, and equally numerous claims by technology providers, it is not surprising that confusion exists. Worse than confusion is the disappointment that results when a blower technology fails to perform as anticipated — and operating cost and efficiency benefits go unrealized.

  • Wastewater Energy Program Case Study: Scheid Vineyards
    Wastewater Energy Program Case Study: Scheid Vineyards

    Scheid Vineyards, located in Greenfield, California, captures wastewater influent from the winery in three aeration ponds to supply the needed biological oxygen demand (BOD) to treat the effluent prior to being used for irrigation. In 2009, the wastewater plant processed over 8 million gallons of wastewater. The existing aeration system was inefficient and maintenance intensive leading the facility to explore alternative solutions.

  • A New Paradigm In Aeration Technology
    A New Paradigm In Aeration Technology

    The DO2E organization sprang from one individual’s attempt to solve an aeration problem in a fish hatchery and realizing that his device to do so had many other applications as well. This device broke up algal blooms as well as aerating, and it was only a short step to modify it into breaking up FOG (fats, oils, and grease) deposits in grease traps and lift stations. This device was patented, thus DO2E was born.

  • Anderson Valley Brewing Company Case Study
    Anderson Valley Brewing Company Case Study

    Anderson Valley Brewing Company had acquired a several different aeration technologies in their treatment ponds over the years including surface aspirators and a diffuser system. They were interested in increasing treatment capacity so they could irrigate using reclaimed wastewater. After discovering ClearBlu and visiting an existing installation they decided to incrementally add UltraFine Bubble aerators to increase treatment.

  • The ClearBlu Solution To Brewery BOD
    The ClearBlu Solution To Brewery BOD

    Real Ale Brewing Company (RABC) started as a small brewery working out of a commercial retail space. As the brewery outgrew their facility they purchased land on the outskirts of town and built a new brewery. Their production level was still low enough at this point for the city to allow direct access to sewer. As RABC continued to be successful and grow, a mandate from the Texas Commission on Environmental Quality stated that the city must require the brewery to treat their wastewater in order to prevent overwhelming the city’s treatment system. RABC began the process of looking into available options for wastewater treatment. They had been introduced to ClearBlu Environmental at the Craft Brewers Conference in 2011 and after careful research the brewery selected ClearBlu to design and install a complete pretreatment and treatment system.

Garrison Brewing Case Study

ClearBlu provided duplexing in-ground lift stations and a self-cleaning waterfall hydroscreen for the brewery who self-installed the equipment.  ClearBlu design and instructions made it possible for the brewery to install the lift stations and screen themselves, as well as to have the screen stand fabricated locally.  ClearBlu lift stations are fabricated from fiberglass which resists deterioration from acidic wastewater and are self-cleaning.  Round basins can be stirred so that they never have to be cleaned out.

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.
