Description of Technology
Descriptions for proprietary technologies are from the Massachusetts DEP Approval Letters for the technology.
Amphidrome and Integral Amphidrome:
The System is a Secondary Treatment Unit (STU) that utilizes a Submerged Attached-Growth Sequencing Bioreactor (SAGSB). The System may consist of an anoxic/equalization tank, which must comply with the design criteria set forth below, and either a single reactor which alternates between aerobic and anaerobic conditions, and a clear well or a single reactor installed in a clear well. Wastewater passes from the anoxic/equalization tank, through a granular biological filter and into the clear well. A pump is then used to reverse the flow back to the anoxic/equalization tank. This cycle is repeated multiple times and the effluent is discharged to the soil absorption system.
Amphidrome Process (nitrogen reduction):
The Amphidrome Process (the ‘System’) is installed in series between the building sewer and the soil absorption system (SAS) of a standard Title 5 system in a manner which neither intrudes on, replaces a component of, or adversely affects the operation of a Title 5 system constructed in accordance with 310 CMR 15.000, subject to the provisions of this Approval.
