ABSTRACT In this research work, Bioremediation technology was used to reduce the heavy contents of the soil collected from the bank of the sewage pond of the University of Nigeria Nsukka. The heavy metals were; zinc (Zn) cadmium (Cd) and lead (Pd). In the bioremediation process, fungi, bacteria and plants were used. The bacteria used were Bacillus cereus, the fungi used was Aspergillus fumigatus and the plant used was Bryophyllum pinnatum (life plant). The combinations of these organisms wer...
ABSTRACT The development and utilization of energy has led to environmental degradation with associated health hazard. Hence the trust of this project is to optimize energy mix in a reliable, affordable, available, safe, efficient, effective and sustainable way at control cost subject to environmental constraints. In other to achieve the desired goal, the optimization model is derived with unit cost of each of the various energy sources as the objective function and environmental impact as c...
ABSTRACT This project is designed to determine households’ access to safe water supply in Ootunja, Ikole-Ekiti, in terms of quality and quantity as the importance of improved water supply to human health cannot be over emphasized. However, safe/improve water supply to most Nigerian cities is still inadequate. In the study area the relationship between water quality, the degree of water source protection and quantity. This aim was achieved through the use of well-structured questionnaire in...
ABSTRACT This research project investigates the geotechnical characteristics of soils in Federal University Oye Ekiti, lkole campus. In this research project, disturbed soil samples were obtained from five labelled TP 1, TP 2, TP 3, TP 4, TP 5 at different locations and at various intervals along the university and were taken to laboratory for relevant soil engineering tests. The relevant soil tests include; particle size analysis, consistency limits (liquid, plastic, and shrinkage limits), n...
ABSTRACT Sugarcane as an agricultural product is a readily available source of food for its sugar content. However, Sugarcane Bagasse Ash (SCBA) is the bi- product formed at sugar industries from the burning of sugarcane after the sugar content has been extracted. Sugarcane Bagasse Ash (SCBA) is a fibrous waste product containing mainly aluminum and silica, calcium ions to produce calcium aluminate hydrate (CAH) and calcium silicate hydrate (CSH) shown in the pozzolanic reaction below. Ca2+ +...
ABSTRACT The sandcrete blocks have been a major material for the construction of structures in Nigeria. This material have provided a means of constructing walls and partition. However, the sandcrete blocks also have the disadvantage of cost and unavailability of materials such as granite, cement and other combining aggregates. Laterite, a readily available material can be efficiently used to produce Laterite bricks which can be fired to improve it's mechanical and physical property. The inc...
This experiment was conducted in order to have a broader knowledge on hydraulic jump and its applications. It was performed in the hydraulic laboratory of the department of Water Resources and Environmental Engineering, Ahmadu Bello University, Zaria, using the TQH23, 2.52m flow rectangular channel and the HID hydraulic bench which provides water to the channel with the aid of the pump incorporated in the HID. Five different discharges were obtained by varying the flow. Hydraulic jump...
Road inventory is the compilation of information about the state and condition of the road system. This study was carried out to collect road data and analyze selected road facilities within the University of Ibadan to serve as an inventory for future purpose. This was done to help resolve the issue of insufficient information about the road facilities within the University premises. In this project a survey of the roads was done which involved the use of photo/video log system and the Glob...
CHAPTER ONE1.0 INTRODUCTION1.1 Background of StudyThere is need for affordable building materials in providing adequate housing for teamingpopulace of the world. The cost of conventional building materials continue to increase asmajority of the population continues to fall below the poverty line. Thus, there is the need tosearch for local materials as alternatives for the construction of functional but low-cost buildingsin bo...
ABSTRACT This study investigation on the mechanical properties of Sagbama rice granite was analyzed to determine the load that would cause ultimate flexural stress on the material when used in concrete construction .This is necessary to make decision on where it is suitable for use. This study requires the production of 12 concrete beams of 100mmx100mmx500mm with sagbama rice granite as coarse and fine aggregate. Three (3) specimens were produced to be tested at 7, 14, 21 and 28days.Mix rat...
Upgrade of wastewater treatment plants to improve nutrient removal.
ABSTRACT Most people living in rural communities, have no access to good domestic water for consumption. The inhabitants depends on rain water, well water and sometimes surface water for consumption. Improper treatment of water gotten from these sources, can lead to the spread of water borne diseases, because, sometimes the water gotten from these sources are turbid. Although, some inhabitants use alum to treat the water so as to make the water clear. But excessive usage of alum to ...
ABSTRACT The purpose of this project work is to assess the strength of No-fines concrete pavement. No-Fines concrete is use in low traffic volume, pathways, sidewalk and parking lots. No-fines concrete is produced by using ordinary Portland cement, coarse aggregates, and water. In this study, Two (2) batches of no-fines concrete each with two different water – cement ratio 0.36 and 0.45 and cement – coarse aggregate 1:4 and 1:6 were prepared to find the mix that generated high compressive...
ABSTRACT This project was undertaken to determine the geotechnical properties of soils along Appleton/Zoo road. A total of nine (9) samples, both disturbed and undisturbed, were collected at chainages - 0+275, 0+325 and 0+525 respectively and each drilled to a depth of 1 m and at sampling depths of 0–0.3 m, 0.3–0.6m and 0.6–1.0 m respectively. These samples were subjected to the following laboratory tests: Particle (grain) size analysis comprising determination of percentage clay, silt...
ABSTRACT The primary objective of this study is to identify the most appropriate herbal plants for the removal of contaminants from water and also to develop a water treatment kit at an affordable cost for the society. Moringa Oleifera was chosen for this study, the effectiveness of these herbs in the removal of fluoride from water shows that Moringa Oleifera is economically viable, physically feasible and socially acceptable. Moringa Oleifera seed is an organic material that has proven eff...
