On paper and in practice, aeration options and their corresponding efficiencies are calculated and compared.
In 2007, Greenville, SC-based Western Carolina Regional Sewer Authority (WCRSA) conducted a rigorous performance test on a new tertiary treatment technology to assess its ability to effectively remove nitrate-nitrogen (NO3-N) without using excess amounts of methanol at its Lower Reedy Wastewater Treatment Plant (WWTP).
This radium removal pilot study was conducted for the City of New Underwood, South Dakota. New Underwood’s water system contains concentrations of radium and gross alpha in excess of the Maximum Contaminant Levels (MCL).
There is a newly-developed technology, the so-called PeriFilter® that will hit the market within the next few weeks. This offers many heretofore technological and economic advantages in the separation of solid phases from liquid phases with concomitant transformation of the solid phases into processable forms for further usage and/or products. It may be used in the separation of solids from liquids in water purification and in wastewater treatment applications as well.
While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
The Ventura Regional Sanitation District’s Liquid Waste Treatment Facility (LWTF) was experiencing a double-threat to safety and productivity.
Best known as the home of outdoor retailer L.L. Bean, the community of Freeport is a popular summer destination on the shore of Casco Bay in southern coastal Maine. In 2010, the Freeport Sewer District brought in engineering firm Woodard & Curran (also of Freeport), to conduct an energy analysis of the Freeport Wastewater Treatment Facility. The assessment revealed that the Freeport plant consumed more than 8.9 kBtu per gallon of wastewater treated, more than double the national average of 4.1 kBtu per gallon. While an outdated oil heating system contributed to the overall inefficiency, the plant’s 30-year-old multistage centrifugal aeration blowers accounted for as much as 80 percent of the electricity consumption.

Until 2012, the Kaufman, TX, Wastewater Treatment Plant (WWTP) operated two separate aeration basins with mechanical surface aerators. As the plant’s equipment aged and required more frequent and expensive repairs and maintenance, the City of Kaufman followed its engineering firm’s recommendation to install a new, more efficient, fine bubble-diffused air system rather than simply replacing its old mixers with in-kind equipment.
Responsibility for analysis results lies with the users themselves or their supervisors. Both are therefore liable for any incorrect interpretations and decisions that are made as a consequence of incorrect data.
Accurately measuring the flow and level of the various liquids and gases that travel through a process industry plant is a critical function for effective and efficient plant operations. Read more to learn ten important industrial process plant functions that can benefit from accurate, repeatable and reliable electronic flow or level measurement.
