Quantification of wastewater sludge dewatering.

Quantification and comparison of the dewatering characteristics of fifteen sewage sludges from a range of digestion scenarios are described. The method proposed uses laboratory dewatering measurements and integrity analysis of the extracted material properties. These properties were used as inputs into a model of filtration, the output of which provides the dewatering comparison.

The Journal of James Wilson: An Insight into Life in North East Scotland Toward the End of the Nineteenth Century .

In the nineteenth century many farmers kept a diary of the farming year to record such features as the weather, crop yields, animal husbandry, and prices. Research into church and people in the parishes of Fordyce and Portsoy in North East Scotland led to the discovery of a four-volume journal kept by James Wilson, a farmer in the Banffshire Parish of Deskford between 1879 and 1892. This journal provides a detailed picture of many aspects of rural life including farming, family, neighbors, religion, friends, and entertainment.

Combination of ferric and MIEX for the treatment of a humic rich water.

Seasonal periods of high rainfall have been shown to cause elevated natural organic matter (NOM) loadings at treatment works. These high levels lead to difficulties in removing sufficient NOM to meet trihalomethane (THM) standards, and hence better alternative treatments are required. Here the removal of NOM was investigated by a new ion exchange process (MIEX) using both bulk and fractionated NOM.
