The purpose of this work is to assess the economic feasibility of forward osmosis and reverse osmosis process for co-treatment of seawater and impaired water. Reverse osmosis has been in use for desalination process of saline water and treatment for advance reclamation of water leading to indirect potable water reuse. But the system is energy intensive, sensitive for membrane fouling, and rejections of salt, micro-pollutants of some membrane are incomplete. The main objective of this study is to evaluate the economic performance of the process stated below: Comparative performance of the combination of forward osmosis and reverse osmosis desalination, effect of membrane fouling and solute rejection (micro-pollutants). Recommendation and cost estimation of FO-RO hybrid system for concurrent treatment of wastewater and saline water. The result showed that membrane desalination processes are economically more feasible than thermal process due to excess heat involved in thermal process. But for hybrid processes, the combination of FO and RO are economically more feasible due to non-existence of external pressure in FO which is the major basis for increasing the energy usage and cost involved in the RO desalination process. The research demonstrates that membrane desalination of sea water is outgrowing traditional practices for serving freshwater needs through thermal desalination process. Hence, this work should thus serve as a paradigm for water security in developing countries, in Europe and regions facing energy challenges.</p> John Igboke Elebe, Sonia Shailong, Aniekan Paul Udeme, Judith Chikodili Anameje, Omeram Bright Ighirigir Copyright (c) 2024 https://auchipolyjournals.com/index.php/areet/article/view/44 Wed, 22 Nov 2023 00:00:00 +0000 DEVELOPMENT OF A MULTIPURPOSE INDIRECT SOLAR DRYER https://auchipolyjournals.com/index.php/areet/article/view/45 <p>This study focuses on the construction and testing of a multipurpose solar dryer for agricultural products. The purpose of the dryer is to effectively dry the products to a safe level before storage. Considerations such as compact-ability, durability, and ease of loading and offloading were taken into account during the construction process. Additionally, the dryer was designed to be a hybrid system, allowing for continuous drying throughout the night. The testing phase aimed to compare the ambient conditions with the conditions achievable inside the dryer. The results showed that the relative humidity was higher in the early hours of the day but decreased as the temperature increased throughout the day. Furthermore, the maximum temperature recorded at the collector (48°C) exceeded the maximum ambient temperature (36°C). The production cost of the dryer was estimated to be 250,000 Naira.</p> K.A Yusuf, Oladipo Ajayi, E.O Atanda, Patience Amatu Copyright (c) 2023 https://auchipolyjournals.com/index.php/areet/article/view/45 Wed, 22 Nov 2023 00:00:00 +0000 DEVELOPMENT OF PALM KERNEL COMPOSITE-BASED EMERY POLISHING SHEET APPLIED IN METALLOGRAPHICAL LABORATORY OF WELDING AND FABRICATION ENGINEERING https://auchipolyjournals.com/index.php/areet/article/view/46 <p>The emery paper used in metallographical laboratory had been successfully developed. It was developed from an agricultural waste product which was prepared into a composite. The developed composite was prepared using palm kernel shell, polyester resin, cobalt naphthalene and ethyl ketone peroxide. The composite specimen were subjected to mechanical testing techniques to determine its physical properties. The characterization tests carried out showed that the palm kernel consist majorly of 61.6% carbon and 30.48 oxygen .The hardness and wear rate tests carried out on the two grit sizes of 250μm and 420μm grains experimentally showed that the 250μm grit size grains had higher Rockwell hardness values and low wear rate than the 420μm grit size grains. Experimental yields showed that 18% and 38% of polyester resin attained wear rates of 1.5 mg/m and 0.7 mg/m respectively for the 250μm grit size while that for 420μm grit size yielded wear rates of 1.6mg/m and 0.8mg/m respectively. This was as attributed to the fine-grained nature of the 250μm grit size grain. An increase in the polyester resin resulted in high hardness values and low wear rate values which is as a result of the high binding strength of the resin.</p> B. N.G. Aliemeke, O. G.

When effective transportation is hindered due to bad roads, bad vehicles, obstructions and delays due to road blocks, unethical taxation, etc, there is a socio-economic effect on both the road users and the nation at large. The need to ensure smooth and effective transportation therefore becomes a necessity for socio-economic growth of a nation. This research work is set out to investigate the socio-economic effect of security check points on highways using a section of the Benin-Auchi express way between Aviele and Agbede in Etsako West local government of Edo State as a case study. In actualizing the desired aim of this research, the researcher collected primary data from the different security check points between 6am to 5pm for a period of one week. The data collected include the total number of vehicles passing through each check point, the types of vehicles and the amount of money collected from each vehicle. The data collected showed that an average of six hundred and ninety-three vehicles pass through each of the security check point weekly and both the military and police check points collects about two hundred and ten million, two hundred and four thousand, eight hundred naira ( ₦210,204,800) annually along the route under survey. With the level of dilapidation of the road pavement that have caused hardship on the road users, the researchers concluded that the total amount of money realized along this route that goes into private pockets if paid into governmental purse will help improve the gross domestic product (GDP) of the country and the maintenance of the route will be successfully carried out hence providing good riding surface for motorist hence improve socio-economic benefit to both the motorist and the nation at large.</p> Osigbhemhe Anavberokhai Isah, Emmanuel Adoga Emmanuel Adoga Copyright (c) 2023 https://auchipolyjournals.com/index.php/areet/article/view/48 Wed, 22 Nov 2023 00:00:00 +0000 DEVELOPMENT OF MICRO–POROUS CERAMIC BRICKS IN PARTITIONING WALLS TO ENHANCE THERMAL COMFORT AND REDUCTION OF “DEAD LOAD” IN BUILDING USING LOCALLY SOURCED RAW MATERIALS https://auchipolyjournals.com/index.php/areet/article/view/72 <p>This study adopted an experimental research design to develop, lightweight micro-porous ceramic bricks in partition walls with a view to enhancing thermal comfort as well as reduction of dead load in building.
