Optimization on performance of single-slope solar still linked solar pond via...

This document describes an experiment to optimize the performance of a single-slope solar still linked to a mini solar pond using Taguchi method. Four parameters were identified that influence the solar still's performance: sodium chloride concentration, the zone in the mini solar pond the still is linked to, the angle of a reflecting mirror at the bottom of the still, and the angle of a reflecting mirror in the pond. Different levels of each parameter were tested. The Taguchi method was used to analyze the results and identify the best performing levels for each parameter. Combining the selected best levels, experimental results showed a 95.54% increase in distillate output compared to a conventional solar still. Theoretical calculations agreed with the experimental results.

The document describes a study that internally and externally modified a double-slope single-basin solar still to improve its productivity. The internal modification involved spreading pebbles at the bottom of the basin to enhance heat absorption and transfer. The external modification fitted an external mirror to focus additional solar rays into the still. Testing found that the internal modification marginally improved production, while combining internal and external modifications significantly increased productivity by 40.86% compared to an unmodified still. The aim was to evaluate how internal and external modifications impact the performance of a double-slope single-basin solar still.

This document discusses enhancing the design of a double basin solar still to optimize its performance. The researchers fabricated a double basin still where the lower basin receives direct sunlight through glass covers on its sides. They integrated external energy sources like reflectors, a flat plate collector, and a mini solar pond with the still. Testing found the distillate output increased from 4333 mL/day for a basic double basin still to 5650 mL/day with reflectors and 6249 mL/day with reflectors, a flat plate collector and mini solar pond. The modifications improved the performance of the lower and upper basins, with the lower basin's relative contribution increasing from 29.75% to 40.6%.

The document describes an experimental study that investigated the performance of three different types of single basin double slope solar stills: a conventional still, a still with heat storage materials in the basin, and a still with an external reflector. The study found that the still with heat storage materials maintained higher water temperature and production rates during declining sunshine hours, while the still with a reflector had higher increases during increasing sunshine hours. Overall, the still with heat storage materials showed a 23.08% higher productivity than the conventional still, while the still with a reflector showed a 62.97% higher productivity. The purpose of the study was to evaluate how well heat storage materials and external reflectors improve solar still performance under changing sunlight conditions.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Joshua Orris

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Recycling and Disposal on SWM Raymond Einyu pptx

RayLetai1

Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste. With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban. Aim: A healthy, safe, secure and sustainable solid waste management system fit for a world – class city. Improve and protect the public health of Nairobi residents and visitors. Ecological health, diversity and productivity and maximize resource recovery through the participatory approach. Goals: Build awareness and capacity for source separation as essential components of sustainable waste management. Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned. Current solid waste management situation: The status. Solid waste generation rate is at 2240 tones / day collection efficiently is at about 50%. Actors i.e. city authorities, CBO’s , private firms and self-disposal Current SWM Situation in Nairobi City: Solid waste generation – collection – dumping Good Practices: • Separation – recycling – marketing. • Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed. • Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products. • Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants. Good practices: Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction. Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled. CHALLENGES: • Resource Allocation.

Microbial characterisation and identification, and potability of River Kuywa ...

Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...

Joshua Orris

Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system. Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs. In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier. The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
