The Benefits Of Adaptive Control Systems
The Benefits Of Adaptive Control Systems

In municipal and industrial wastewater treatment, there has been a shift from manual to automatic process control in order to increase efficiency and improve effluent quality. An increasingly popular approach includes installing a variable frequency drive (VFD) to constantly adjust the amount of air injected into the process to control dissolved oxygen, NH4, and/or NO3 in the wastewater treatment.  This approach works well from a process control standpoint.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Case Study: Mazzei AirJection® Aeration System Installed In Alabama Field Erected WWTP A design/build contractor needed a quiet, efficient aeration system for a 250,000 GPD field erected WWTP. This plant was to be located adjacent to a school. A restriction on ambient noise at the location of the proposed WWTP required a quiet aeration process. By Mazzei Injector Company, LLC
  • Packaged Wastewater Treatment Plant Meets Tricky Challenge
    Packaged Wastewater Treatment Plant Meets Tricky Challenge

    Packaged Wastewater Treatment Plants offer many advantages, flexibility notwithstanding. One plant in particular, located in Georgia, needed to be upgraded to handle the increased flows from a growing city and to address new effluent discharge regulations.  The tight plant site offered minimal opportunity for routine expansion of the packaged wastewater plant volumes, hence special designs were needed. Learn how this 200,000 GPD system is thriving.

  • Case Study: Andrews Infrastructure - Sewer Main remote inspection Andrews Infrastructure provides remote sewer-main inspection to municipalities. A problem for the firm was the lowering and retrieval of its cameras and umbilical cords down deep shafts
  • Case Study: Aerator/Mixer System Gives China WWTP Trouble-Free Performance
    Case Study: Aerator/Mixer System Gives China WWTP Trouble-Free Performance

    Aeration Industries International, Inc. is playing a key role in cleaning up water worldwide to help preserve the earth’s most precious resource, water. When the Chinese city of Lin An planned an expansion to their oxidation oval system, officials were looking for a new type of aeration system that would offer process performance and trouble free operation. The company's AIRE-O2 TRITON process aerator/mixers were the ideal solution for the Lin An wastewater treatment facility.

  • Case Study: More Power. More Control. Cuyahoga County is the most populous county in Ohio, with nearly 1.4 million residents. Part of Greater Cleveland, the county is named after a Native American word meaning "crooked river." By The Gorman-Rupp Company
  • Submersible Aerators Blast Off At Naval Air Station WWTP
    Submersible Aerators Blast Off At Naval Air Station WWTP

    When the Jacksonville, Florida Naval Air Station needed to increase oxygen in their aeration basins, they turned to RWL Water. Five submersible HURRICANE aerators provide bottom-up mixing, drawing surface air and dispersing it in a 360-degree pattern near the basin floor. Long bubble hang time results in excellent oxygen transfer, and ensures excellent BOD and ammonia removal, treating flows up to 3 MGD.

  • Dairy Processing Plant Maximizes Performance With New Scaling-Resistant Solution
    Dairy Processing Plant Maximizes Performance With New Scaling-Resistant Solution

    Wastewater from dairy applications has high amounts of calcium and phosphorus. This characteristic may cause scaling on the media of a Moving Bed Biofilm Reactor and may cause poor COD removal. Veolia was able to retrofit the client’s existing MBBR with the newly designed Z-MBBR media by AnoxKaldnes, which improved the operation of the entire wastewater system.

    Lift Stations: Attacking The 'New Sewage' With Vaughan Chopper Pumps

    Disposable, throw-away products are making raw sewage pumping tougher than ever. The Jefferson Street Pump Station at the City of Centralia, WA had a problem demanding a cost-effective solution. By Glenn Dorsch, P.E, VP/Chief Engineer, Vaughan Co. Inc.

  • Case Study: Gorman-Rupp Addresses Concerns For Higher Head, Greater Flow Through Research & Development Increasingly, end users in the construction, industrial and wastewater markets are realizing the need for higher heads or to pump liquids greater distances, over challenging topography. Professional Engineers and municipal designers have previously had little choice but to overextend pump performance limits of conventional self-priming centrifugal trash pumps, potentially shortening the life of the pump and risking safety issues in the process. By The Gorman-Rupp Company
  • Headworks Bio Commissions First IFAS System In Costa Rica
    Headworks Bio Commissions First IFAS System In Costa Rica

    In late 2013, Headworks Bio Inc. was awarded a contract with General Contractor Soluciones Tecnicas Ambientales, S.A. (SOLAMSA) to supply an IFAS system to upgrade the existing Ptar El Roble conventional activated sludge (CAS) treatment facility in Puntarenas, Costa Rica — the first IFAS installation in the country.
