Environmental Bio-Detection Products Inc. (EBPI) is a Mississauga-based biotechnology company specializing in the development and manufacture of biological testing kits for a variety of cellular metabolism byproducts in environmental samples. Seneca collaborated with EBPI on a NSERC Engage for Colleges, completed in January 2020. As follow on to the existing prototype, EBPI would like to continue to collaborate with Seneca and Professor Kyle Valdock from Seneca's School of Electronics and Mechanical Engineering Technology (SEMET) to optimize the design of the prototype unit developed during the Engage for Colleges project. The goal of this additional project is to adjust the existing pumps and PLC coding, as well as addressing water leakage through the system. In addition, EBPI would like to investigate alternatives to the existing filter used in the system. The present system provides a flow rate of 20 to 50 ml/min to a 47mm SPE filter. It would be advantageous and cost effective for EBPI to develop a reusable or a disposable holder for smaller (5.5, 7, 10 mm) SPE filters. In order to do this, a new filter housing must be developed and the flow range of the unit will need to be widened.
