Integrated Solar And Hydraulic Jump Enhanced Waste Stabilization Pond

ABSTRACT This study on the integrated solar and hydraulic jump enhanced waste stabilization pond (ISHJEWSP) is aimed at determining the effect of variations in solar radiation, hydraulic jump, hydro-kinematic factors and pond geometry, on the treatment efficiency of wastewater in the ISHJEWSP. An equation to account for these effects was derived, calibrated and verified. An empirical regression model for the prediction of the Biochemical Oxygen Demand (BOD5) in the ISHJEWSP for sewage treatm...

Estimation Of Biogas Reactor Constants Using Multiple Regression Analysis

ABSTRACT Biogas generation is accomplished by anaerobic digestion of biodegradable material in a biogas digester. Anaerobic digestion as a process requires dynamic model for predicting process performance. Mathematical model for biogas production from anaerobic digesters described in this study was used to predict biogas generation using experimental data. Multiple regression analysis was used in analyzing two sets of data, the first sets of data contains four different experimental results ...

Strength And Microstructure Of Lateritic Concrete Containing Palm Kernel Shell (Pks) As Partial Replacement For Coarse Aggregates.

ABSTRACT This research work reports the investigation carried out to determine the strength and microstructure of lateritic concrete containing palm kernel shell (PKS) as partial . replacement of coarse aggregates. The study employed different mix proportions, which resulted in casting and testing 148 cubes at 7, 14, 21, 28, 60, and 90-days of curing, to determine the best and economic proportion that will give compressive strength. The materials and methodology phase of this research evalua...

Strength Characteristics Of Soils In Ikole Campus Of Federal University Oye Ekiti, Ekiti St A Te, Nigeria

ABSTRACT The development of soil and rock properties for geotechnical design purposes begins with developing/defining the geologic strata present at the site in question. Therefore, the focus of geotechnical design property assessment and final selection shall be on the individual geologic strata identified at the project site. This research work was been carried out to determine the shear strength characteristics of soils in Ikole Campus of Federal University Oye Ekiti, Ekiti State. Classif...

Design Of A Water Storage And Transmission System For Wastewater Reuse In Covenant University

   ABSTRACT This research is focused at designing of water storage facilities of size 875,000 litres (750,000 litres for underground water storage, and 125,000 Litres for elevated steel tank) of treated wastewater and its transmission system for the storage and re-use of treated wastewater. The project is aimed to structurally design water storage facilities and its transmission system from the reservoir to the overhead tank for the re-use of treated wastewater in Covenant University. The...

Manufacturing and Application of Fatliquor from Castor Oil for Upper Leathers

Abstract Castor oil is classified as semi-drying oil because it oxidizes on exposure to air, giving a gummy film, and can be highly sulphated to make it emulsible in water. In the raw condition it is seldom used in fatliquoring of leathers because crude oil does not emulsify with water and hence the failure of the fatliquor process. Castor seeds were collected, sundried, and crushed. Castor oil was leached in a soxhlet apparatus using hexane as a solvent. An oil content of 28.4%was obtained....

Structural Behavior of Power Transmission Towers

ABSTRACT This research is concerned with analysis and design of the power transmission towers. Three types of the power transmission towers were considered in this research to investigate their structural behavior. Data have been collected about the types of towers, their usage, and the types of the applied loads. The study concentrated on the 220 kV double circuit’s Wawa- Wadi halfa Transmission Line Project, the three types of the transmission towers has different configurations and same...

The Evaluation Of Steel Slag Effect On The Compressive Strength Of Concrete

Abstract This study was conducted to test the possibility of benefiting from the blast furnaces slag resulting from the production of steel at Giad Factory south of the city of Khartoum –Sudan. The study aimed to determine the effect of partially replacing some of the concrete mix components with steel slag to study the effect on the compressive strength and workability of the concrete mixture. A mix design was prepared for standard according to the British and US by using another mixes whe...

Geotechnical Characterization Of Failed Sections Along Ikole - Oye Ekiti Road, Ekiti State, Nigeria

ABSTRACT This research project assesses the geotechnical characterization of soils used for the construction of the failed sections along Ikole- Oye Ekiti Road, Ekiti State, Nigeria. This road spans 23kms. The study area falls within coordinates 7. 7979306° N (Oye) - 7. 7982660 N (Ikole) and 5.3285505°E (Oye) - 5.5144930°E (Ikole). It is a known fact throughout the world that the conditions of any road largely depend upon its geotechnical properties such properties includes soil strength,...

Feasibility Of Rain Water Harvesting In Ikole Ekiti For Domestic Use A Focus On Quality And Quantity

ABSTRACT Water scarcity is a problem in many parts of the world. In some regions, there is physical water scarcity because there are not enough resources of water to meet the increasing demand, while other parts of the world have an economic scarcity, where resources are more abundant but poor governance and other problems render water unavailable for most of the population. Where the problem is economic water scarcity, there are many solutions that could ameliorate the problem, but most tim...

Assessment Of Drainage Structures From Babalola Junction Down To Ayegun River Of Irare Estate, Oye Ekiti, Ekiti State, Nigeria

ABSTRACT Globally, natural disasters are becoming places lately, and they are the results of climate change due to natural forces. Some of these disasters like floods, earthquakes, landslides and draught happen, resulting in loss of human lives and properties. Flood occurs when two or more acres of dry land or two or more properties are inundated by water or mudflow. In this study, the reconnaissance survey of the study area was carried out. The topographical map of the area contributing run...

Evaluation Of Cost And Time Control Using Earned Value In Building Projects In Khartoum State

Abstract In the period between 2016-2019 and the problem of searching for roads lies in the cost and time of projects in the construction experience in Sudan from exceeding the time specified in the contract between the owner and the executing party and exceeding the cost in contracts The research aims to know the cost and time control, monitor the project status and forecast the final work cost, to address weaknesses and defects in the plan and early identification of risks at the beginnin...

The Effect Of Cost Management In Construction Projects’ Planning In Sudan

ABSTRACT The construction industry in Sudan is an important sector due to its enormous contribution to the country’s economic development. This in terms of employment opportunities and attraction of Foreign Direct Investments which grossly contributes to the country’s GDP. However due to the geographical, political, social and financial situation of the country, many construction projects are prone to delay, cost overrun or unsatisfactory quality, these three functions form the core of ...

Evaluation Of Water Quality Modelling Parameters: Towards The Evolvement Of Re-Aeration Coefficient For Rivers In The Nigerian Environment

ABSTRACT This study was carried out on River Atuwara in Ota, Ogun State, Nigeria with the aim of developing a coefficient of re-aeration model applicable to River Atuwara and other rivers in the Nigerian environment. This was achieved by sourcing for data once every month from 22 sampling locations of interest within a pre-selected segment of the river over a period covering the dry and wet seasons. The data collected include hydraulic data (depth, width, velocity and time of travel) and wat...

Removal Of Lead, Cadmium And Nickel By Sawdustmodified Tropical Clay For Use As Landfill Liner Material

ABSTRACT Access to groundwater, a major source of direct drinking water in many developing countries, should not be assumed as access to safe drinking water. There is a need to prevent or minimize the contamination of groundwater, especially arising from solid waste disposal. This research work investigated the suitability of using clay and bentonite modified with sawdust as landfill liner materials for minimizing the migration of Pb2+, Cd2+ and Ni2+ in order to protect the environment and p...
