Water has been one of the essential factors in the development of human settlements. Especially with the increasing population of human and industry, the demands for the quantity of water are also increasing (Binnie et al., 2002). This has become a serious concerned as the high quality of water supply has been very limited due to the contamination of water with municipal, agricultural and industrial waste that has lead to a decreasing water quality. This lead to a water treatment process as public
Clean water supply is essential in establishing and maintaining a healthy community. There are two sources of water supply which are the surface water and ground water. Most natural waters are not suitable for consumption as it is contaminated by pathogens and also natural chemicals and minerals. In addition, as a city grew, wastes from human activities contaminate most of the water supplies. Water treatment plays an important role to properly treat a contaminated source of water supply in order
The forth step in water treatment is a disinfection. During this stage, disinfectants will be added to kill or inactivate microorganisms that can cause disease in humans. The research on the water sample shows presence of protozoa that cause diseases such as Entamoeba histolytica, Giardia lamblia and Naegleria fowleri (Nemerow, Agardy, Sullivan, & Salvato, 2009). Some protozoa and viruses, which may present in water supplies are extremely harmful. There are two kinds of disinfection which is primary
INTRODUCTION The main aim of wastewater treatment is to produce wastewater that can be safely disposed off, without causing harm or infection in humans and other animals. Wastewater generated by all processes - ranging from the personal use of water to industrial use - needs to be disposed in rivers and lakes. The pathogens present in wastewater can cause serious enteric infections and therefore need to be removed before they can proliferate via the sources of water such as lakes and rivers. The conventional
Hydric Soils as a Part of Water Treatment in Wetland Systems Most basically, a hydric soil is defined as "A soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (Kent, 1994, p. 26)." Included by this definition in the United States Department of Agriculture/Soil Conservation Service's list Hydric Soils of the United States are all of the poorly drained and very poorly drained soils and most of the somewhat poorly drained
The waste water is represent of the major sources of pollution to water bodies after being discharged into rivers without proper treatment or partial treatment as it contains toxic organic substances that lead to a decline in natural water and disruption the balance of the environment ,that causes the occurrence of water pollution . Wastewater treatment processes rely on assimilation of microorganisms and enzymatic effectiveness in breakage chains carbon of soluble organic pollutants , as sewage
Background: Waste water treatment plants are essential to communities of all sizes and must work efficiently. Waste water treatment plant primary priority and responsibility is the treatment of incoming sewage water by the removal of biological and chemical wastes so it can be treated and recycled for future use. There are many government agencies and standards set forth to govern and observe the successful treatment of sewage such as: the Department of Environmental Quality, the National Pollutant
Introduction 1.1 Background Disinfection is applied in water as well as wastewater treatment as a finishing step so as to destroy pathogens but the cause of concern regarding the disinfection process is the formation of disinfection byproducts (DBPs). Natural organic matter (NOM) in water has been considered as the predominant DBP precursors. Disinfectants are powerful oxidants that oxidize the organic matter present in water forming DBPs. Chlorine, ozone, chlorine dioxide, and chloramines

Introduction: Water is one of the most important substances on earth. All plants and animals must have water to survive. If there is no water, there would be no life on earth. It covers about 71% of the Earth’s surface, and is vital for all known forms of life. But only 2.5% of the Earth’s water is fresh water. Continuing population growth is significantly reducing per capita water availability and increasing industrialization and urbanization. Due to industrialization and urbanization, it is
The treatment of surface wastewater is aimed at bringing contaminated water back to its previous state for domestic use or otherwise. Some of the sources of wastewater include industrial effluents from manufactures, agricultural effluents, agro-industrial as well as domestic wastewater from sinks, bathtubs, toilets, and so on. Particles in the water from the various sources include bacteria, organic matters, and sand which cause the water to be turbid or discoloured in appearance and have an unpleasant
It is important that everyone know of the need to improve our energy and water savings and assist in reducing the use of electricity, water, and non-renewable fuel sources. There are a number of non-chemical, non-mechanical water treatment technologies. Many of these are known by names such as electronic, magnetic, electrostatic, electromagnetic, and AC induction. The history of these devices goes back to at least 1952. Claims for and against the effectiveness of such systems have a long history
aquarium as the water within the tank and the lighting given its inhabitants. Since water is the medium that the aquarium inhabitants must live in, it is the most vital component in any tank. The quality of the water used will directly effect how successful the aquarium is. The chemical balance of the water must be watched closely. If the salt content varies too much, or harmful chemicals build up, the water will kill the inhabitants of the tank. Since fresh pure sea water is not readily
INTRODUCTION Ultrafiltration is a water purification process that can be used for the removal of particulates and macromolecules from raw water to produce potable and drinking water. They have been used to either replace existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems employed in water treatment plants. When treating water with high suspended solids, UF is often integrated into the process, utilizing primary (screening
been used to disinfect water. The usage of chlorine in water treatment was first applied back in 1990’s. Chlorine has been mostly used in water treatment than any other application because it is very active and it destroys a wide range of harmful bacteria and viruses in the water. Disinfection of drinking water is one of the most important and successful accomplishment for public health because it has done a major reduction of diseases that are caused by drinking unsafe water, such as typhoid, cholera
get clean drinking water, or don’t even not have access to clean drinking water? People all over the world, even in North America, don’t have access to clean drinking water or have to walk very far just to drink water. The main areas where this problem is prominent is in third world countries, and this is due to the lack of money and sanitation (Millions Lack Safe Water). Due to this lack of sanitation, water borne diseases can grow and infect people who consume it. Clean water is very important
Autism: A Disorder of Conflicting Causes and Treatments Despite its 50 year-old diagnosis, autism is still one of the mostly commonly contracted and rarely treated childhood diseases. Studies suggest that as many as 1 in 500 children may display autistic symptoms. Manifestations of this disability include the stereotypical physical contortions and hand-flapping motions commonly associated with autism, as well as inability to relate to the outside world, limited social skills, lack of concentration
