  • A Submerged Attached Growth Bioreactor for Decentralized Wastewater Treatment

    ABSTRACTThe Amphidrome® process is a submerged attached growth bioreactor (SAGB) that has been used in Massachusetts, Connecticut, Rhode Island and New Jersey for decentralized wastewater treatment systems ranging in size from 440 gpd to 150,000 gpd. The two primary advantages of a SAGB are the small volume requirement and the elimination of downstream clarification. Five years of data from four ...

  • Investigation of Nitrification and Nitrogen Removal from Centrate in a Submerged Attached Growth Bioreactor

    The purpose of this study was to investigate the nitrification and nitrogen removal from centrate produced in the dewatering process of an anaerobically digested sludge, using a single-unit, single-zone submerged attached growth bioreactor (SAGB). The nitrogen loading varied from 0.54 - 1.51 kg-N/m3-day and the organic loading varied from 0.07 – 0.64 kg-bCOD/m3-day. The ...

  • Post Lagoon Nitrification in Cold Climates

    A Submerged Attached Growth Reactor (SAGR) Demonstration Site has been in operation following a primary aerated lagoon in Steinbach, MB since August 2007. This system provides nitrification, with influent winter water temperatures (post lagoon) below 0.5 degrees Celsius. The performance objective of the system was to achieve effluent cBOD5 and TSS levels of less than 10 mg/L, and ammonia of less ...
