Composting of Town Refuse by the 'Edelmist' Process
Conversion of organic wastes, including night-soil, into manures has been practised for a number of years. Among the methods so far developed, those of Hutchinson and Richards (1921), Waksman and co-workers (1927), Fowler (1930) and Howard and Wad (1931) are most extensively adopted. These methods involve fermentation under essentially aerobic conditions. They are fairly rapid, but they also in...
متن کاملA Hygienic Method of Composting Refuse with Night-Soil
years. In many parts of India, it lias long been the practice to utilize night-soil as manure without any previous treatment. It is also occasionally used for preparing ' poudrette' in combination with mud and refuse. In recent years, however, the desirability of preparing composts from night-soil and different forms of organic wastes under aerobic conditions is being increasingly realized as e...
متن کاملFate and Effects of Silicone Polymer During the Composting Process
Silicone (polydimethylsiloxanes, or PDMS) fluids are widely used in industrial and consumer products, and may find their way into municipal biosolids that are eventually applied to the land. In soil PDMS breaks down into dimethylsilanediol which is then either volatilized or biodegraded. Since biosolids are often composted prior to land application, this paper investigates fate and effects of P...
متن کاملEffect of Abrasion Process on Reflectance Factor and Color Change of Chenille Woven Fabrics
This paper focuses on effect of abrasion process on color and reflectance factor changes of dyed woven fabrics containing 100% acrylic chenille yarns in weft and cotton warp yarns. Three fabrics having 12, 14 and 16 weft per centimeter were dyed with three basic dyes in different hues. Four different abrasion levels, i.e. 50,200,400 and 650 were selected to abrade samples. The obtained results ...
متن کاملInactivation mechanisms of pathogenic bacteria in several matrixes during the composting process in a composting toilet.
This study aimed to compare the inactivation rate and the mechanisms of pathogenic bacteria in three matrixes (sawdust, rice husk and charcoal) during the composting process. The inactivation rate was evaluated with Escherichia coli strain and the damaged parts and/or functions were evaluated with three different media. Normalized inactivation rate constant in three media and from three matrixe...
