Reducing Decomposition Time in Landfills by an Aerobic Process [PDF]
, 2001 This experiment was performed to determine if sludge produced by the paper industry could be composted faster by promoting the aerobic degradation process. To perform this experiment, I chose a sludge produced by a virgin pulp mill.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

A review of the harvesting of micro-algae for biofuel production [PDF]
, 2012 Many researchers consider efficient harvesting is the major challenge of commercialising micro-algal biofuel. Although micro-algal biomass can be ‘energy rich’, the growth of algae in dilute suspension at around 0.02–0.05 % dry solids poses considerable ...

SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...

Inhibition of Protease Activity in Muscle Extracts and Surimi from Pacific Whiting, Merluccius productus, and Arrowtooth Flounder, Atheresthes stomias [PDF]
, 1993 Muscle extracts of Pacific whiting, Merluccius productus, and arrowtooth flounder, Atheresthes stomias, were assayed for proteolytic activity using azocasein as a substrate. Pacific whiting extracts showed maximum activity at pH 5.0-5.2 and a temperature
