PROJECT TITLE: A STUDY INTO DESIGN SOLUTION FOR RECYCLING AND REUSE OF WASTEWATER AT VEHICLE WASHING BAYS IN GHANA: A CASE OF CAPE COAST AND SEKONDI –TAKORADI METROPOLIS BY JERISCOT HENRY QUAYSON REG. NO. 05AG0514177 CHAPTER ONE INTRODUCTION 1.1 Background of the Study Water is one of the essential commodities in every human society for the day to day activities. Many industries use water for their various productions and this, vehicle washing bays are not exempted. Vehicle washing bays uses large quantity of water in performance of their activities, such as cleaning the exterior and interior motor vehicles and other accessories such as engine, carpets etc. In view of this, there is the need to manage water judiciously…show more content…
The accumulated sediments or sludge may contain heavy metals such as chromium, lead, zinc and nickel. Therefore, to avoid pollution of water bodies, there is the need to recycle the wastewater that are generated at vehicle washing bays across the country for reuse; using the natural filtration process to safeguard the environment. Usually, vehicle washing bays use more soap and water. However, Riddle (2003) attested to the availability of environmentally-friendly and modern vehicle washing techniques. According to Féris et al. (2001), technique for recycling wastewater generated from vehicles wash in Brazil reported a high turbidity and colour removal of about 90% and 75%, respectively). Main features were the low surface tension given by a residual concentration of wash wastewater which facilitates the generation of micro bubbles; the presence of oil and grease yielding light floc, and a fairly low suspended solids concentration. It is against this background that the researcher aim at developing a simple and economical design solution for recycling and reuse of the wastewater generated at vehicle washing bays in Ghana; through natural process of…show more content…
Vehicle washing bays uses a lot of treated water and therefore their operations become incomplete when there is shortage of water. Nonetheless, none of the washing bays in the study areas have a system that is able to recycle the volume of water taken from GWCL for reuse. This means that large volumes of treated water is being wasted daily. The danger ahead is that Cape Coast and Sekondi-Takoradi Metropolis may experience water shortages in the near future if the wastage continues. It is against this background that the researcher seeks to develop a simple and economical design solution for recycling and reuse of the wastewater generated at vehicle washing bays in both cities. 1.3 Research Questions 1.3.1 Main Question What economic design solution when developed at vehicle washing bays will maintain the operations and hence minimize their water wastage? 1.3.2 Sub question a) What are the existing facilities in use at the various vehicle washing bays in the two Metropolis? b) What is the quantity of water that is being produced by Ghana Water Company Ltd? c) What is the demand of water at the vehicle washing bays? d) What kind of recycling design facility will be appropriate for vehicle washing bays 1.4 Aim / Objectives of the Study 1.4.1 Aim of the study The aim of the research is to develop a simple and economical design solution
