The environmental research project concentrated on developing technology
to facilitate water reuse opportunities, improved wastewater pre-treatment,
and to extract alternative fuels from waste materials. Considerable
work focused on increasing treatment flow rates through the Taylor
vortex device while continuing to test ultraviolet light disinfection
efficiency using this concept on opaque/turbid fluids such as chiller
overflows, brines, and marinades. System flow rates were able to be
doubled through innovative design changes to the unit’s rotor.
Preliminary
design work was also conducted to better manage potential fluid temperature
elevation that can result from UV (ultraviolet) lamps heating. In
addition, studies were carried out to evaluate the use of struvite
precipitation
as a method of optimizing nutrient removal from scalder overflows.
Preliminary results have been very promising. Finally, several methods
were examined to improve the efficiency of recovering biodiesel from
waste oil and fats. Initial results indicate that traditional methods
for producing biodiesel can be greatly improved in terms of throughput. |
