Methane Production by a Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water
… dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced by reciprocation mixing to decrease pumping costs and the risk of media clogging. </p> <p>Three packed-bed digesters containing walnut shells as media …

Comparison of Biofilm Media in Reciprocating Biofilters Treating Dairy Flushwater
… (RCA), vertical-flow plastic media, and walnut shells – were operated at a 2-day THRT over the course of a 16 week study. The TN removal efficiencies for rock aggregate, RCA, plastic media, and walnut shell media were 43%, 53%, 25%, and 69% respectively. Surface based mass TN removal …

Modeling the Hydrodynamics of a Fluidized Bed
… the minimum fluidization as an input. Ground walnut shells were used to represent biomass because the material fluidizes uniformly and is classified as a Geldart type B particle. Two-dimensional simulations of ground walnut shells were analyzed to determine parameters that cannot easily be …

Exploitation of agricultural and forestry waste: from the recovery of bioactive compounds for nutraceutical applications to the production of innovative materials
… environmental, economic, and social issues. The shells of Pistacia vera, Prunus dulcis, Corylus avellana, and Juglans regia species represent the most abundant by-products and have the potential to be further processed into value-added nutraceutical ingredients and other innovative materials. In …

Dairy Manure Flushwater Treatment by Packed-Bed Anaerobic Digesters
… pilot-scale packed-bed anaerobic digesters with walnut shell medium was researched for treating dairy freestall barn flushwater. Reciprocation mixing was evaluated as a means to lessen channelization in the media bed and to improve biogas production and organic matter removal at ambient …

Rheology And Organic Filler Interactions in Phenolic Resin Formulations
… using agricultural waste products like walnut shells and corn-cob residue. These organic waste products act as fillers that reduce the cost, increase the viscosity, and affect the rheology of the fillers. Wheat flour is added as an extender to reduce cost and affect the tack of the …
