Approximately, 0.3793 m 3 CH 4 /kgVS was generated biomass. research indicated that available population on Lower Volta River in year 2020 could potentially generate a methane yield 53.676 × 10 6 . volume gas had potential to produce an annual electricity output 110.792 kWh, which be integrated national grid. analysis positive results with initial total...

Diesel adulteration not only reduces engine performance and lifespan but also has a stiffening effect on the economy. Therefore, regulatory agencies petroleum laboratories are constantly adopting various methods to ensure that commercial diesel is pure of good quality. Despite introduction solvent tracer analysis as reliable means detecting adulteration, most still depend physicochemical parameters an indicator adulteration. This research aimed document feasibility using quality detect Neat...

Abstract The production of leather from animal skins and hides through tanning processes began in the pre-historic ages. Despite origination new making techniques such as chrome which is being employed extensively today, traditional method primarily vegetable still practised mostly artisanal tanneries developing nations including Ghana. Artisanal making, thus, contributes beneficially to rural livelihood. Nevertheless, growth this sector has been stifled by lack innovative technologies...

The criminal act of fuel (gasoline) adulteration still remains a global worry due to its environmental, health and economic effect. Current methods for the detection have not been effective in most developing countries associated cost implementation. Therefore, there is need fast, reliable cheaper approach screening adulterants fuel. This study combined FTIR analyses with Chemometric (multivariate) techniques qualitative quantitative determination four possible adulterants: kerosene, diesel,...

Unlike high-rate anaerobic digesters that employ some mechanism to retain microbial sludge mass, low-rate systems use sufficiently long hydraulic retention times ensure process stability, which becomes economically unattractive for treating large quantities of waste. This study presents the attainable region develop a new strategy enhance stability digesters. By considering three digestion cases, diary manure only (batch 1) or with granular 2) lagoon (batch) as innoculum, following findings...

This study sets out to develop an approach that couples attainable regions and fuzzy multicriteria decision methods for modeling optimal configurations of multistage digesters without using a kinetic model the process. The is based on geometric analysis methane curves as their shapes contain valuable insight into substrate biodegradability characteristics during anaerobic digestion. With case abattoir waste, results indicate batch operation policy involves four sequencing reactors operated...

Anaerobic digestion involves multiple reactions, and when operated as a single stage, the process conditions are only suitable for all reactions with no particular reaction being optimized, hence limiting overall performance. Multistage anaerobic digestion, in which digesters network designed to optimize each reaction, but very few writers have drawn on any systematic procedure design of digester networks. This study is about multistage networks, contrary traditional articles that focus...

Nearly 6494 boreholes with iron (Fe) and manganese (Mn) concentrations above permissible limits of 0.3 mg/L 0.4 respectively in Ghana have been abandoned because ineffective water treatment solutions.
