Application of Modified Fmtlxlylz Dimensional Equation to Sludge Filtration using Sludge Drying Bed

ABSTRACT A natural filtration on sludge drying bed has resulted to a modified equation incorporating the compressibility coefficient. The equation was derived using the application of a modified FMTLXLYLZ dimensional analysis technique. The equation was validated using experimental data from a pilot scale sand drying bed and there was a close agreement between theory and experiment with a correlation coefficient ranging from 0.94 to 0.98. The experimental slope and intercept was found to be ...

Influence of Hydrologic & Sediment Parameters in Modeling Stream Flow of Osun River, Osun State Nigeria

CHAPTER ONE         INTRODUCTION 1.1     Background to the study The water is the most important natural resource especially in the arid or semi-arid zones that face high population growth, scarcity of freshwater, irregularity of rain- fall, excessive land use change and increasing vulnerability to risks such of drought, desertification and pollution. Thus, the availability and the sustainable use of this resource become the core of the local and national strategies and politics...

The Effects of Sugar Cane Bagasse Ash as Supplementary Cementitious Material in Production of Concrete

ABSTRACT Sugarcane Bagasse is the fibrous residue leftover when sugarcane is squeezed for its juice. Bagasse ash is obtained by subjecting Bagasse to calcinations using furnace. This work is aimed tat using Bagasse Ash as a replacement in the production of concrete. The bagasse was collected from dumped in a market in Kano and thereafter sun-drie to eliminate any trace of moisture. It was then taken to the blast furnace for calcinations(controlled burning) at a temperature of 1250OC for 25mi...

Investigation of the Spatial and Temporal Variation of Sediment Yield and Surface Runoff in Offa Watershed Kwara State

ABSTRACT In this research, an hydrological modelling tool, soil and water assessment tool (SWAT) used to investigate the spatial and temporal variation of sediment yield in a watershed. The model was run for 31years using spatial data such as Digital Elevation Model, soil map, land use and precipitation, wind and solar radiation. The results showed that the maximum value of surface Runoff was estimated as 19100.034mm in the year 2005 while the minimum surface Runoff was 1000.671mm in the yea...

Effect of Date Palm Seed Ash as a Supplementary Cementitious Material in Concrete

Abstract This study investigates the effect of Date Palm Seed Ash (DPSA) as a pozzolan on the workability, compressive strength and water absorption capacity of concrete. Temperature regulated kiln was used to burn the Date Palm Seed (DPS) into DPSA in two stages: it was first burned for eight hours at an optimum temperature of 590oC and then cooled for two days. It was again burned for three hours at an optimum temperature of 630oC for eight hours and was air cooled again for three days. The...

Assessment Of The Impact Of Effluents From Bonite Bottlers And China Paper Industrieson The Water Quality In Karanga River, Tanzania

ABSTRACT The raise in industrial development in catchments has left no option but to discharge industrial effluents into water bodiessuch as sea, rivers and streams. Discharging of industrial effluents into water bodies if not done with care through effluent pre-treatment and assurance of complience with allowable standards can lead to water quality impairment. This study was carried outto assess the effects of the effluents from Bonite bottlers and China paper industries on water quality in ...

Assessment Of The Effectiveness Of Blue Nile And White Nile Water Treatment Plants In Khartoum State )A Case Study Of Bahri, Mogran, Alshajara And Jabal Awlia Plants)

Abstract Treatment of water is considered as a critical challenge especially in developing countries since this treatment is an essential facility to conserve the public health and environment by eliminating of waterborne diseases and pathogens and make it acceptable to consumers. The objective of this research is to assess the efficiency of Blue Nile (Bahri and Mogran) and White Nile (Alshajra and Jabal Awlia) water treatment plants which consist to conventional water treatment units such a...

Assessment of groundwater quality for Umbada, District,Omdurman, Sudan

Abstract: This study was dealing with assessment of groundwater quality and its fitness for agriculturaland domestic uses for Umbada district in western Omdurman, Sudan. The objectives of the study were to determine the groundwater quality through chemical and microbiological analyses for the samples taken from the studied boreholes in the area under investigation. Water samples for five groundwaterwells were collected in poly ethylene bottles and analyzed physically, chemically and bacterio...

Post-Independence Evaluation Of Air Transport Safety In Nigeria

ABSTRACT This research evaluates air transportation safety in Nigeria. Records of aircraft crashes in Nigeria were extracted from different archives to create a database of air traffic incidences within the air space of Nigeria since Independence. Statistical overview of air transportation accidents in Nigeria using accident data to examine a national trend in air transportation disasters was carried out. Results of the analysis showed that air traffic accidents in Nigeria have increased per...

Synthesis, Characterization and Catalytic Investigations of Pt- Based Binary (Bimetallic) and Ternary (Trimetallic) Nanoparticles

Abstract This work tests the hypothesis that nanoparticles of 75 at.% platinum (Pt) composition and anisotropic morphology, will outperform standard catalysts in (PEMFC) hydrogen fuel cells. A survey of the scientific literature on this topic is first presented. The synthetic strategies which were developed for the preparation of novel Pt-based binary (bimetallic) and ternary (trimetallic) nanoparticles, containing nickel (Ni), cobalt (Co) and/or vanadium (V), are then described. The synthes...

Development Of Iron And Steel Processing Plant In Kenya

Steel plays a very key role in the transformation of an economy, as it is the key driver in any industrial revolution majorly being used in transport, building and construction, power generation and machinery. It is in this regard that the study of iron and steel in Kenya is important. This study sought to determine the viability of setting up an iron and steel processing plant in Kenya, develop a process design for such a plant and determine the plant's economic feasibility. This research em...

Ageing And Axial Cyclic Loading Studies Of Displacement Piles In Sands

Abstract An investigation is presented into the mechanisms governing both the ageing and axial cyclic loading characteristics of displacement piles in silica sands. The thesis considers first the state–of–knowledge regarding the axial capacity of displacement piles in silica sands. Three main areas of uncertainty are identified; the stress regime setup by installation, the mechanisms of ageing that lead to capacity increases with time (set-up), and the effects of axial cyclic loading. Ne...
