ABSTRACT
Treatability testing can be carried out on- or off-site; indoors or outdoors and at bench, and pilot and/or demonstration scales. Off-site treatability testing is usually carried out at a central test facility and is often used to define the proof-of-concept of a new use of the Eco-Engineered Bioreactors (EEBs) ecotechnology using relatively inexpensive methods, before later, often larger scale, more sophisticated on-site testing is entertained. Generally, pilot-scale treatability testing is carried out indoors, although in some cases the test bioreactors can be set up outdoors, or even temporarily moved outdoors if desired. Pilot-scale EEB R&D and treatability testing at Centre for Alternative Wastewater Treatment are usually carried out inside a large greenhouse there that has in it large environmental chambers and a walk-in refrigerator, allowing tests to be conducted over a range of temperatures. The kinetic and other scale-up parameters determined during the treatability test were used to design the full-scale EEB System for Buffalo Niagara International Airport.
