Labscale Evaluation of Immobilization Media

Labscale Evaluation of Immobilization Media Final Report

SUMMARY The performance of a 3-phase up-flow integrated high rate anaerobic digestion reactor system utilizing corn cob biochar as biofilm support was characterized at 10 liter total scale on waste trap grease wastewater at defined hydraulic retention times (HRT) and packing densities. Performance was evaluated in terms of chemical oxygen demand (COD) reduction, total volatile organic acid vari...

A Labscale Hybrid Rocket Motor for Instrumentation Studies

An interest in plume spectroscopy led to the development of a labscale Hybrid Rocket Facility at the University of Arkansas at Little Rock (UALR). The goal of this project was to develop a reliable, consistent rocket motor testbed for the development of plume spectroscopy instrumentation. Hybrid motor technology was selected because it has proven to be safe and inexpensive to operate. The proje...

Use of the labscale tangential flow diafiltrator to remove tetrameric hemoglobin from polyhemoglobin, purify hemolysate, and concentrate polyhemoglobin.

The Labscale tangential flow diafiltration system in conjunction with polyethersulfone Biomax filters (both purchased from Millipore Inc.) were used in the following studies: (1) A crucial step in the preparation of polyhemoglobin (polyHb) is the removal of tetrameric hemoglobin (Hb), which can cause adverse side-effects. The efficiency for this depends on the integrity of the 100kDa filters. T...
