Aeration System Prevents Septic Conditions
Aeration System Prevents Septic Conditions

Circa 2010, Carollo Engineering designed and implemented expansions at wastewater treatment plants in Delano, California and Reedley, California to handle increased flows of up to 8.8 MGD and 5.0 MGD respectively. The proposals for both facilities specified a need for storage and processing of secondary sludge produced by the processes’ secondary clarifiers. Mazzei Injectors were selected to provide an efficient, zero maintenance method of freshening and mixing the sludge. Read the full case study to learn more.

  • Ultrasonic Vs. Radar Level Technology In The Water Industry
    Ultrasonic Vs. Radar Level Technology In The Water Industry

    In recent years, the debate about which technology is best suited for water and wastewater level measurement and monitoring is heating up. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and open-channel measurement applications in the water industry.

  • Top 10 Questions You Should Ask When Purchasing A Control Valve
    Top 10 Questions You Should Ask When Purchasing A Control Valve

    Automatic control valves, much like everything else we purchase these days, are not all created equal. Some fall into the high quality bracket with pricing to match, while others hover closer to the lower quality and price sensitive end of the scale. Unfortunately, when evaluating control valve prices, it is not always clear what you are being offered and what standards the valve actually meets. Here are a few questions to consider and ask the supplier to ensure you get years of trouble free operation that lasts longer than it takes the sales person to drive out of your parking lot!

  • Minimizing Energy Use At Pump Stations With Extreme Variable Flows
    Minimizing Energy Use At Pump Stations With Extreme Variable Flows

    Every spring, the wastewater municipality in Dalarna, Sweden, experienced melting snow and heavy rainfall that caused a dramatic increase in pump station inflow. To handle this seasonal volume, the station had oversized pumps that consumed more energy than needed during drier months. This case study illustrates how the installation of a variable-speed pump controller decreased energy consumption by almost 50 percent while allowing for variations in flow.

    Pharmaceutical Effluent Recycling In India

    A renowned pharmaceutical company in Pune, India, installed a water treatment system to recycle pharmaceutical process wastewater for reuse. Ultrafiltration was chosen as pretreatment to a reverse osmosis system, and the feed water was tertiary treated pharma effluent.  Soon after operation began, the existing UF membranes were repeatedly choking, and QUA of­fered Q-SEP ultrafiltration modules to the customer to replace the existing UF membranes.

  • Performance Of A Conventional Surface Water Plant Using Mixed-Oxidants For Microflocculation And Final Disinfection
    Performance Of A Conventional Surface Water Plant Using Mixed-Oxidants For Microflocculation And Final Disinfection

    The surface water source is from snow-melt and summer thunderstorm run-off from the mountains. This water is detained in McClure Reservoir (7876 ft elevation) and Nichols Reservoir (7483 ft elevation) upstream from the CRWTP, a conventional plant built in 1974 with a design capacity of 8 MGD. Because the City has limited surface water rights, and due to decreased demand, the treatment plant usually shuts down for 60 to 90 days during winter. The reservoirs thaw in spring and turn over in autumn, and during the summer rainy season, raw water turbidities may exceed 5 NTU. By MIOX Corporation

  • Total Kjeldahl Nitrogen: Simplified With s-TKN™
    Total Kjeldahl Nitrogen: Simplified With s-TKN™

    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.
