Wastewater Treatment Case Studies and White Papers

  1. Reliable Production Of High Quality Permeate For Irrigation

    Following one of the driest periods on record in California, farmers in the San Joaquin Valley faced restricted water allocations.

  2. Flow Data Red Flags: When To Act

    Accurate flow measurement is critical to most water and wastewater processes. Red flags may pop up to indicate meter problems, but which ones should lead you to act — and when? The answer depends on the type of meter, what it is used for, and whether the readings are local or remote.

  3. Clearing Channels And Tanks Of Rag And Fiber Produces Benefits Beyond The Tanks

    Reduction of ragging is merely one of the benefits the EscaMAX® Perforated Plate Screen bestows upon its implementer. But this is such a huge factor, that mitigating it brings night-and-day results in other areas such as reducing debris in the grit channel, increasing space for energy-producing biosolids in tanks, and releasing cleaner end products. 

  4. Innovative And Cost-Effective Solutions For Activated Sludge And Nutrient Removal Applications
    Municipalities across the nation grapple with the treatment challenges associated with escalating state and federal regulatory requirements on the heels of limited or declining budgets. By Ayman Shawwa, P.E., Ph.D., BCEE, PMP, Aeration Industries International
  5. MBR Helps Ohio WWTP Expand Its Facility Within Its Existing Footprint

    The Carrollton Wastewater Treatment Plant located in eastern Ohio, was upgraded from conventional activated sludge technology.

  6. Top 10 Considerations When Converting To On-Site Hypochlorite

    Transporting pure salt - the raw material needed to generate sodium hypochlorite onsite – is more cost effective, stable, and safer, than transporting and storing bulk sodium hypochlorite, or gaseous/liquid chlorine cylinders from local chemical suppliers. The conversion to on-site hypochlorite generation can be achieved by adhering to these design guidelines.

  7. Anglian Water To Use Atlas Copco ZS Blowers At Wastewater Treatment Re-Development Sites

    Anglian Water, one of the UK’s largest water and wastewater treatment companies - operating over 1000 wastewater treatment works in the East of England - has chosen Atlas Copco’s low-pressure ZS blowers to supply air to the aeration diffusers at four of its wastewater treatment re-development sites.

  8. Article: 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
  9. Harmful Algal Blooms – What’s In Your Drinking Water Intake?

    In August 2014, the city of Toledo, Ohio informed its residents (~500,000 people) that they should not use tap water for any purposes including bathing and cooking. The culprit: microcystin, a toxin produced by blue-green algae, had been detected in the city’s finished drinking water at concentrations 2.5 times the World Health Organization’s guideline value.

  10. Z-88® Radium Treatment Process - City Of Bridgeton, New Jersey

    This radium removal pilot study was conducted for the City of Bridgeton, New Jersey’s Well No. 19 treatment facility. The Bridgeton water system contains concentrations of radium and gross alpha in excess of the Maximum Contaminant Levels (MCL).
