  • A sustainable system to Weather all seasons - Case Study

    Aerator upgrades help wastewater treatment plant survive cold Vermont winters More than two decades ago, cold Vermont winters brought a small Wastewater Treatment Facility to a halt with brush rotor icing problems. A major upgrade that included the Aire-O2® aspirator aeration system ...

  • Case Study of an IFAS System – Over 10 Years of Experience

    ABSTRACTThe Annapolis Water Reclamation Facility (WRF), which is owned and operated by the Anne Arundel County Department of Public Works in Annapolis, Maryland, has undergone, over the last ten years, a transition from conventional activated sludge to an Integrated Fixed Film Activated Sludge (IFAS) system for Biological Nutrient Removal (BNR) to, most recently, a dual anoxic zone process for ...

  • French WWTP installs LIT open channel UV-system

    Recently O.E.I. France, distributor of LIT for the French market, installed a LIT open channel UV system in the South of France close to the Mediterranean Sea. The system is placed in the municipal Waste Water Treatment Plant (WWTP) of the village of Canet-en-Roussillon with 10.182 inhabitants. The capacity of the WWTP however is based on the summer season population of 66.000 inhabitants. The ...

  • Enhanced nutrient removal MBR system with chemical addition for low effluent TP

    A pilot study was conducted to test an membrane bioreactor (MBR) process for combined biological and chemical P removal to achieve a very low effluent total phosphorus (TP) concentration of 0.025 mg P/L. With the data from the pilot test, a simulation study was performed to demonstrate that: (1) the pilot system behaviour (effluent quality, MLSS, etc.) can be modelled accurately with an activated ...

  • The development and application of the hybrid centrifugal - dissolved air flotation system for wastewater treatment

    Abstract Solid/liquid separations are integral part of any wastewater treatment system. Particles heavier than water are commonly separated in sedimentation clarifiers. On the other hand, particles with densities lower than that of water are most often separated with flotation systems. This manuscript describes the development of hybrid centrifugal - dissolved air flotation system. The ...

  • Fixed vs. Moving Bed Systems: Aeration and Mixing Efficiency

    The aeration design for a biofilm system, such as moving bed or AccuFAS fixed-film systems, is more complex than a standard activated sludge system. In a biofilm system, the aeration design must satisfy the oxygen demand for required treatment, provide mixing, and control biofilm ...
