DESIGN OF SEDIMENTATION TANK TO RESUSCITATE PHYTOREMEDIATION IN OVERLOADED OBAFEMI AWOLOWO SEWAGE TREATMENT PLANT

The discharge of raw sewage or improperly treated sewage into water bodies has always had a threatening effect on aquatic lives and that of human that uses the water on the downstream. Such is the case of Awba Lake which is currently being polluted by effluents from Obafemi Awolowo sewage treatment plant. The treatment plant is currently overloaded and macrophyte (water hyacinth) used for phytoremediation in the treatment plant can no longer survive under such high organic condition.This proj...

Comparative Assessment of Rice Husk Ash, Powdered Glass and Cement as Lateritic Soil Stabilizers

COMPARATIVE ASSESSMENT OF RICE HUSK ASH, POWDERED GLASS AND CEMENT AS LATERITIC SOIL STABILIZERS.ABSTRACTThis paper compares the stabilizing effects of three different materials, namely: rice husk ash, powdered glass, and cement on the properties of lateritic soil. The basic properties of the lateritic soil were first obtained through colour, moisture content determination, specific gravity, particle size distribution and Atterberg limits tests. Each of the stabilizin...

ABSTRACT This project work deals with the design and fabrication of a suitable journal bearing test apparatus which can help in visualizing the behavior of journal bearing and its characteristics, and in determining the bearing parameters such as load bearing capacity, maximum oil film temperature, viscosity of lubricant, oil film pressure, and coefficient of friction based on experimental analysis. The work covers the design of a test apparatus which can be utilized to check the be...

A Model for Economic Production in Manufacturing Industries Under Unstable Power Supply.

The research study presents the development of a model for Energy cost in manufacturingindustries under irregular power supply. The work considers power consumption in the operationof production machines, hence cost incurred in running of these machinesParameters such as machine types for production, numbers of machine types for production andpower ratings of machines for production were also considered in the development of the modelThe study employs linear programming approach in formulatin...

Production of Kenaf Fibre Reinforced Polyethylene Composite for Ballistic Protection

Kenaf reinforced polyethylene composites for ballistic protection was produced in this work. The samples of alkaline treated and silane-coupled non-woven matted kenaf fibers were cut to the required dimensions and oriented vertically and horizontally in combinations with a virgin high density polyethylene (VHDPE). The composite panels were produced using Box-Behnken 3-variables settings. The following factors settings were used (molding temperature: 160 0C to 200 0C; molding time: 60 minute...

CONSTRUCTION OF SMOKE DETECTOR

AbstractA smoke detector is a device that senses smoke typically as an indicator of fire or non- smoking zone.  In order to ensure human safety and safeguard property against fire in both domestic and commercial settings, different solutions for smoke detection have been developed, a comprehensive literature was carried out on smoke detector, this project describes the construction and design of a micro controller smoke detector, it discusses the components used, design methodology and t...

PHOTOCATALYTIC DEGRADATION OF PHARMACEUTICAL WASTE WATER USING TITANIUM DIOXIDE AS PHOTOCATALYST

ABSTRACT The potential advantage and application of the photocatalytic process using titanium dioxide as the photocatalyst to treat industrial waste water in UV irradiation has been reported. The aim of this work is to investigate the effectiveness of photocatalytic degradation using TiO2 in treating pharmaceutical waste water. Wastewater was collected from the homogenous tank of effluent treatment plant (ETP) of a Pharmaceutical company. The raw sample was tested and the COD...

Energy Audit, Optimisation and Management of Liquified Natural Gas Plants With Renewable Energy Resources Around the Plant: A Case Study of Brass LNG Limited, Brass Island, Nigeria

An energy audit on the Brass Liquified Natural Gas plant at Brass Island former Agip facility was carried. The average offshore windspeed and wave return periods for 12months  were measured for their wind and wave energy potentials. Also,  the solar insolation for the location was collected for a 12month period. A pilot design based on techno-economic analysis was made for a wind-solar- gas turbine hybrid power system and results showed it's cheaper, environmentally friend, and more efficie...

RECOVERY OF HEAVY OIL USING THE TOE-TO- HEEL AIR INJECTION, (THAI) METHOD BY ANEKWE MICHAEL I. (PETROLEUM ENGINEERING DEPT. FUTO)

ABSTRACT This project work deals on the feasibility of transferring the Toe – To – Heel Air Injection (THAI) technology which is a new in-situ combustion method of heavy oil recovery from Alberta, Canada, where the technology has recorded success with high rate of recovery to South-West, Nigeria (Ondo state) for efficient heavy oil recovery. In this work, the textural, reservoir, physical and chemical properties of oil sand in Nigeria were compared with that in Canada where the te...

Physio-chemical and micro bacterial assessment of bottled water samples sold in bauchi metropolis

ABSTRACT             The advent of sachet and bottled water has increasingly filled the gap in household water security. This research work was carried out to assess the quality of bottled and sachet water sold in Bauchi metropolis. Thirty (30) water brands consisting of twenty (20) sachet water brands and ten (10) bottled water brands were assessed for their physical, chemical and microbiological parameters using standard analyti...

Prediction of Generalised and localized carbon steel corrosion using improved Norsok and Papavinasam Models

Carbon steel corrosion is a commonly encountered issue in pipelines transporting hydrocarbons containing corrosive agents such as CO2, H2S and water. As a result, several corrosion prediction models have been put forward over the years although no standard model exists for corrosion prediction in the industry. Two of such models are the Norsok model for predicting sweet generalized corrosion and the Papavinasam model for predicting localised corrosion which are both insufficient to accurately...

INVESTIGATING THE OPTICAL AND MECHANICAL PROPERTIES OF PHOSPHORESCENT SILICONE RUBBER AS A COMPLEMENTARY SOURCE OF LIGHTING

The household lighting cost accounts for 10% of the electric bill, changing the light bulbs effectively can reduce the long term energy costs significantly. In Nigeria, where less than one percent of the population has access to 24 hours of interrupted power supply there is a need for a complementary, renewable source of light which provides enough illumination at a reasonable price, with assured safety using it and also using for a long duration of time before the need to replace it. Recentl...
