Pressure screening studies with wood pulp
… in paper making to separate components of a wood pulp slurry (water, wood fibre and solid contaminant material) and to concentrate the wood fibre. The complex solid-liquid and solid-solid mechanisms involved in pressure screening are still poorly understood. This thesis reviews the literature on …

Electrochemically mediated oxygen bleaching of pulp
… oxygen bleaching of unbleached Kraft softwood pulp. The atmospheric reactor was used to help elucidate the effects of reactants in electrochemically mediated oxygen bleaching. In addition, the electrochemical behaviour of the reactants, which was measured by cyclic voltammetry, was correlated …

Pulp reaction to anorganic bovine dentin
… reparative dentino-genesis in the dental pulp. The teeth of two monkeys were capped with bovine dentin mixed with methyl cellulose and histologic analysis was made at 21 and 42 days post-operatively. At the 21-day interval, seven of the 17 teeth capped with the experimental material were …

Microparticle retention aid systems in mechanical pulp suspensions
… retention and drainage of thermomechanical pulp (TMP) suspensions loaded with precipitated calcium carbonate (PCC) is studied. While starch is primarily added as dry strength agent in PCC-filled TMP suspensions, it also has a significant role in improving retention and drainage. Tapioca …

On site measurements of kraft pulp pump system efficiency
… This work concerns the on-site measurements of pulp-suspension pumping efficiency. This involves the measurement of pump head, flow rate and power consumption. Provided that consistent flow measurements are available, it is possible to reliably and non-invasively measure actual pump system …

The aerobic digestion of semi-chemical pulp mill wastes
Semi-chemical pulp mills discharge large quantities or waste materials into the streams of the nation. If the flow of the stream is such that the waste does not become sufficiently diluted, biological reactions occur which deplete the dissolved oxygen in the stream, sometimes to the point where it …

Color removal from pulp and paper wastes by coagulation
… to remove color and organic carbon from the pulp and paper wastes from the Union Camp Corporation, Franklin, Va. Based on a preliminary analysis of the data collected during this research, either alum or ferric chloride may be used to remove color from pulp and paper wastes. An effluent with …
