Modification of microbial electrolysis cells (MECs) by altering the sizes of the anode and the cathode, or their interaction with the liquid stream affects the performance of the MEC, but it remains difficult to quantify how much each change will contribute to the overall performance. Through this study, a method...
Application of sewage sludge to soils increases the trace metal
content and the organic content of soils. The complexation of indigenous and added metals with organic constituents must be studied to
evaluate metal availability to plants and animals.
The water soluble organic fractions (WSOF) from an agricultural
soil (W), a...
Algae have shown great potential as a source for renewable fuels. However, current production schemes have not been able to prove a sustainable energy return on investment due in part to the high costs of nutrient addition and the energy required for drying the biomass. Integrated algae-dairy production systems have...
An experimental biomass combustion facility has been
built and established at Oregon State University. The
furnace, or Biomass Combustion Unit ( BCU ), uses an augertype
fuel feed system, grate-type fuel support with under
and over fire air supply.
Fourteen pellet species from five States - Alaska,
Washington, Oregon, Idaho,...
This investigation explored the use of microcosms as a tool for
studying the dynamics of tropical aquaculture ponds. The potential use
of rabbit excreta as a pond fertilizer in integrated farming systems was
also investigated.
Twelve insulated fiber glass tanks were utilized as microcosms to
simulate earthen ponds. Seven hand-sexed...
Effective combustion of waste fuels requires an
understanding of the fuels characteristics. Gaseous and
particulate emissions, ash residues and combustion
properties are of interest to many; those that produce and
sell heating units, utilities interested in using the fuels
for power generation, regulatory agencies, municipalities
needing to solve a disposal...
