    Cheyenne Board Of Public Utilities In Cheyenne, Wyoming Successfully Moves From Calcium Hypochlorite Tablets To Microclor® On-Site Hypochlorite Generation

    The Cheyenne Board of Public Utilities (BOPU) operates the water and wastewater systems for the capital of Wyoming which has a population of more than 63,000. Located in the fast growing Front Range Urban Corridor, BOPU is challenged by growth, periodic water scarcity and aging infrastructure.

  • How Do You Know If Your Ozone Contacting System Is Well Mixed?
    How Do You Know If Your Ozone Contacting System Is Well Mixed?

    Mixing is something that is often taken for granted when designing systems for water and wastewater treatment. Perhaps “taken for granted” is too harsh a term. Let’s instead say that while designing a treatment unit operation or process, mixing as a phenomenon is automatically assumed to occur — an assumption that forms the basis for process controls, performance guarantees and measurement methods and locations.

  • Plant's Aeration Output Increased While Electricity Is Decreased

    Located in New Haven County, Connecticut, in the eastern USA, the wastewater treatment plant in Meriden has a design inlet flow of 43,911 m3/day (11.6 mgd) with a maximum inlet flow of 143,386 m3/day (38.0 mgd). Upgraded in the 1960s and 1980s, the plant has been in existence since the 1800s.

  • When To Consider An Alternative To Thermal Dispersion Meters

    Maintaining a firm grip on blower output within digesters at wastewater treatment plants is the key to stable dissolved oxygen levels that support an optimal biological cycle. However, the most common type of device used to measure aeration in the activated sludge process — thermal dispersion flow meters — is not always the best fit. The good news is that wastewater plant operators have multiple alternatives.

  • Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
    Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency

    One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.

    The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.

  • How To Use ATP And DNA In A Wastewater Nitrification Monitoring Plan
    How To Use ATP And DNA In A Wastewater Nitrification Monitoring Plan

    Ammonia removal is a key metric for assessing wastewater treatment facility performance. This is because ammonia contributes to aquatic life toxicity. Furthermore, nitrogen, along with phosphorus, is a driver of receiving water eutrophication. Eutrophication, which simply is an over-enrichment of nutrients, can be detrimental to environmental and public health. It can result in harmful algae blooms, dissolved oxygen depletion, fish kills, and other damaging impacts.

  • 4 Benefits Of Utilizing Reverse Osmosis Wastewater Treatment For Reuse
    4 Benefits Of Utilizing Reverse Osmosis Wastewater Treatment For Reuse

    When a municipality or business wants to reuse their wastewater, some applications require more treatment than others due to the quality of the wastewater. Many standard wastewater treatment systems consist of pretreatment, primary treatment, and secondary treatment stages. By the end of the secondary stage, a majority of the pollutants, solids, organics, inorganics, and metals have been removed or reduced. This is where reverse osmosis wastewater treatment can be utilized in a third stage process.

    Global Perspective On Water In The Circular Economy

    Isn’t it ironic that our beautiful blue planet, covered 70 percent with water, is struggling to meet citizens’ water needs? Yes, and the reasons are obvious. Out of the Earth’s total water, less than 3 percent is available as freshwater, and a portion of it is actually accessible. Uneven distribution of fresh waterbodies and population across the globe further skew water supply and demand ratios. Also, climate change, deforestation, desertification, droughts, floods, and depletion of natural waterbodies resulting from anthropogenic and natural activities add to these miseries.
