effect of digested distillery spent wash on nodulation,the photosynthetic activity of chickpea plants, measured as chlorophyll a fluorescence, was maximum at 10% and 100 m 3 ha −1 of digested spent wash, while a decrease was observed at higher concentrations. with an increase in the concentration of digested spent wash, there was a decrease in n and p uptake by chickpea plants..removal of melanoidin from molasses spent wash using fly,the major problem associated with the molasses industry is the production of large quantities of brown-colored effluents known as spent wash. it has been reported that molasses spent wash in alcohol fermentation is nearly 15 times of the total amount of alcohol pro-duced . disposal of such huge quantity of waste stream without.treatment methods of distillary spent wash: a review,molasses from the sugar factory is the major constituent in the sugar industry. molasses is the by-product of sugar industries. the effluent of distillery is known as spent wash. spent wash is the approximately 13-16 times more by volume to that of the alcohol. it is highly organic brown in color. following values are describes spent wash.(pdf) utilization of molasses spentwash for production of,utilization of molasses spentwash for production of bioplastics by waste activated sludge. download. related papers. biotechnological conversion of agro-industrial wastewaters into biodegradable plastic, poly β-hydroxybutyrate. by suresh kumar. turning waste to wealth-biodegradable plastics polyhydroxyalkanoates from palm oil mill effluent.
the production and the characteristics of the spent wash are highly variable and dependent on the raw material used and various aspects of the ethanol production process , .wash water used to clean the fermenters, cooling water blow down and broiler water blow down further contribute to its variability .distillery spent wash has very high biological oxygen demand (bod), chemical oxygen.use of molasses spent wash in cement industry,use of molasses spent wash in cement industry. use of molasses spent wash in cement industry co-processing of distillery spent wash concentrate in cement industry quality of molasses used etc.effect of molasses in concrete as a water reducing and,molasses is a by-product recovered from the sugar refining process, due to molasses increases the fluidity of fresh concrete and also delays the hardening time of cement paste.effect of molasses as an admixture on concrete.uses of spent wash in cement industry,mining plant. uses of spent wash in cement industry. uses of spent wash in cement industry. spent wash co processing in cement – samac mining. patent wo2012077124a1 – a method for co-processing of distillery 14 jun 2012… steps of: -neutralization of spent wash (optional), -concentration the spent read more.
the majority of distilleries use molasses as a feed stock. of concentrated spent wash as fuel in cement/steel industries along with other fuel/raw materials. read more protocols/ guidelines related to treatment & disposal options.characterization of molasses spent wash and its,matter.molasses spent wash is one of the major components of growth media used in many industrial processes but presence of melanoidin, a recalcitrant compound causes several toxic effects on the living system. this is an attempt to study the physico-chemical characteristics, microbial screening of molasses spent wash and use of mushroom in.characterization of molasses spent wash and its,molasses spent wash is a by-product of sugar cane, sugar beet and citrus industries. molasses contains mixture of uncrystallizable sugar and non-sugar components. it is one of the most difficult waste products to dispose due to its acidic ph, dark brown colour, high ash content, high percentage of dissolved organic and inorganic matter.molasses spent wash is one of the major components of
driving forces in the treatment of molasses spent wash using different technologies (kazemi et al., 2015). for every litre of ethanol production, about 15 l of molasses spent wash is generated (yadav et al., 2011). spent wash is very acidic in nature, highly charged in organic matter, and is considered to be a troublesome and complex industrial.cod and colour removal from molasses spent wash using,the aim of this study was to investigate the removal of chemical oxygen demand (cod) and colour from a melanoidin solution using activated carbon produced from bagasse fly ash (bfa). melanoidins are heterogeneous polymers and major contributors to the dark brown colour of molasses spent wash, which is an extensive cause of environment pollution..ethanol from molasses (with spent wash treatment,molasses is the mother liquor left after the crystallization of sugarcane juice. it is a dark coloured viscous liquid. molasses contains about 45-50% fermentable sugar. the demand for ethanol has been continually increasing on account of the growth of user industries and use of ethanol as a fuel in the country.
