    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.

  3. Sturbridge POTW: Greater Capacity For High Flow Events, Enhanced Clarification For New Regulations
    12/16/2014

    Sturbridge, Massachusetts historically suffered from periodic blooms of filamentous bacteria that caused bulking in the secondary clarifiers of their three activated sludge package plants.

  4. Concord, Massachusetts WWTP - A Low-Cost, 20-Year Solution To Ever-Tightening Phosphorus Limits
    12/16/2014

    Prior to 2007, Concord, Massachusetts wastewater treatment plant operated under a NPDES permit that allowed a seasonal phosphorus limit of 0.7 mg/L. But with the issuance of a new five-year permit with a phosphorus limit of 0.2 mg/L and the probability that future limits could reach as low as 0.05 mg/L, Concord needed a treatment solution that would be reliable and cost-effective today and over the long term.

  5. Sustainable Nutrient Removal With IFAS
    11/21/2014

    With the AnoxKaldnes Hybas IFAS system, the City of Cocoa Beach, FL, met the challenges of tighter nutrient regulations, site constraints, and operating conditions. And the project met the city’s goals to meet these challenges with a simultaneous decrease in energy use. On top of that, the city did not need to increase operations time or staffing to meet these goals. With the AnoxKaldnes Hybas IFAS system, the city is now meeting stricter nutrient regulations – and doing it sustainably.
