Última Characterization of brewery waste water and evaluation of its potential for biogas production CIGR Journal Murunga, Sylvia Injete; Mbuge, Duncan Onyango; Gitau, Ayub Njoroge; Mutwiwa, Urbanus Ndungwa; Wekesa, Ingrid Namae. The issue of global warming and climate change is strongly receiving public attention and has become a major environmental concern both nationally and internationally. Brewing industries are among the largest consumers of water and the largest source of organic effluent mostly from the brewing, cleaning, and cooling processes which must be treated to allowable levels to reduce environmental pollution. Close to 10 L water is used for every 1 L beer that is brewed, though the amount of water in the final beer is small. A study was undertaken to characterize and assess the variations in the quality of untreated brewery waste water. Samples from different process streams including brewing line, clean in place line and mixing line from two brewing industries in...

Ano: 2016 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/3759 The Effect of Agricultural Soil Compaction on Physico-Mechanical Properties of Silt Loam Soils of Njoro, Kenya CIGR Journal Abich, Samuel Otieno; Gitau, Ayub Njoroge; Nyaanga, Daudi. In order to cope with the demand for more food for the ever growing world population, it has become necessary to intensify farming.Agrivultural machines movement across the field increases soil compaction. The objective of this study was to rstablish the effects of soil compaction 0n selected soil physico-mechanical properties. Afactorial experiment in a completely randomised design was used. Tests were conducted on 18 plots to investigate the effect of five tractor wheel pass treatments (1, 2, 3, 4, 5) and a no whool treatment on bulk density, penetration resistance, soil cohesion, angle of internal friction and soil shear strength at three depths (0 -20, 20 - 30 and 30 - 40 cm) with three replications per plot. The results showed that increasing the...
