CHAPTER 1 INTRODUCTION Despite the fact that the world is two-thirds water, most of it is not potable. Population expansion and industrial development has deteriorated the quality of freshwater reservoirs around the world and has caused freshwater shortages in certain areas. To meet the growing population’s demand for freshwater, wastewater treatment techniques aimed at remediating municipal wastewater and industrial wastewater should be employed. Municipal wastewater mainly consists of domestic

1. INTRODUCTION 1.1 PROBLEM STATEMENT Membrane technologies usually play a big role in wastewater treatment processes. Recently, due to the stricter regulation for drinking water quality, improvements of membrane materials and modules, smaller footprint, relative simplicity of installation, membrane technologies have drawn an increasing attention in water treatment processes [1]. Recent years, population growth, urbanization and industrialization has rapidly increased the clean water

ABSTRACT The cosmetic industry is steadily probing for discovery of new formulations with effective delivery system having biological activity. Nanoscience is one of the widely used technologies and finds its applications in the cosmetic industry. Nanotechnology thus is a transformative and new technical revolution and is being used for alteration of physical properties of an enormous range of products from moisturisers, sun blocks, anti-ageing lotions to liquid make up, hair styling and colouring

Colorimeter A colorimeter is a piece of equipment that is used to measure the concentration of dilute solutions (intensity of light). The colorimeter is mainly used to determine the concentration of a known solute (chemical that is placed into a solvent and dissolved) in a given solution by using Beer-Lambert’s Law which states that the concentration of a solute is proportional to the absorbance. According to Beer’s law, “when monochromatic light passes through the coloured solution, the amount

Introduction: Need for wastewater reclamation Wastewater reclamation is the process whereby wastewater is treated using physical, chemical and even biological methods, so that the effluent obtained can be used again, providing that it meets a series of parameters which varies according to its use. The need for wastewater reclamation has increased due to the ever increasing demand for water which has led to a rise in water stress both in terms of quality and quantity of water (Gerke S., 2001). With

The very first time, Zopf was described the genus Rhodococcus in 1981 and then redefined in 1977 to accommodate a number of strains that resembled but did not belong to the genera Corynebacterium, Mycobacterium and Nocardia.1, 2 Thereafter, considerable changes were made to the classification of the genus. Some species have been combined, some reclassified in new genera and new species have also been described.1 at present there are over 40 species classified under the genus Rhodococcus.3-4 The

Water Contamination and Disinfection Tabatha Hatler SCI 207: Dependence of Man On The Environment Alisha Etheredge September 8, 2013 Water Contamination and Disinfection Introduction Water contamination is vastly becoming an alarming issue across the world. We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that

There are various reasons that prediction of natural gas price is imperative to producers, suppliers, traders, market makers, and bankers involved in natural gas exploration, production, transportation and trading as well as consumers involved in utilization of natural gas (Mishra, 2012). The prices of energy commodity including natural gas price are very volatile that make the parties engaged in a high risk and uncertain activities. More accurate forecast of the price, help them to select an appropriate

Have you ever imagined that Earth is no longer available due to pollution? As shown in Wall-E, people recognize that wastes can lead Earth to be unavailable for all lives because of toxic gas from wastes. In each day, tons of wastes are create, and they are disposed with vary disposal methods. Unfortunately, current disposal methods have limitations; landfill and incineration create harmful chemicals that pollute Earth. Even if people live only with necessity of life, wastes are still created and
