Solar water disinfection

COMPLIANCE AND EFFICACY OF SOLAR DISINFECTION OF DRINKING WATER ON CHILDHOOD DIARRHOEA: (A case study of Manyatta and Nyalenda peri urban areas of Kisumu East.) CHAPTER ONE 1.1 INTRODUCTION Zepha (2008), states that, “Solar Water Disinfection (SODIS) is a simple, cheap and environmentally friendly method for treating microbiologically contaminated drinking water at household level.”(as cited in Moses ,Zephaniah & Jacques,2008, p.3). According to EAWAG (2008), SODIS utilizes solar radiation to inactivate

feasibility of implementing solar water disinfection in areas without access to clean drinking water. The purpose of this assessment is to provide you with two different perspectives from which to evaluate the proposed technology of solar water decontamination from an ethical perspective. I have found 2 main areas to consider for the ethical impact of our technology: (1) Health benefits gained from drinking clean water and (2) the environmental impact with regards to using plastic water bottles.

to clean water is unspeakably easy. Technology has revolutionized what it means to get clean water that is safe to drink, shower in, and play in. The water that is consumed by humans comes from water treatment plants, making it perfectly safe. Many people don’t think about where their water comes from, or the process it has to go through in order for it to be consumable. However, many countries do not have access to clean drinking water. In other places, people have to clean their own water using the

Contaminated Water and UV Light In today’s world, the access to clean water is unspeakably easy. Technology has revolutionized what it means to get clean water that is safe to drink, shower in, and play in. The water that is consumed by humans comes from water treatment plants, making it perfectly safe. Many people don’t think about where their water comes from, or the process it has to go through in order for it to be consumable. However, many countries do not have access to clean drinking water.

will suggest that the grant of these funds is to be used to provide clean sources of water and sanitation for the Bolivian people. In the construction of this argument, I will begin with a broad summary of Bolivia’s developmental status, along with its nature, and the effect it has on its citizens. Next, I will outline that the channeling of these funds will through NGOs and will go towards the building of water purification and sanitation systems in both urban and rural areas. Third, I will explain

One of the main advantages of solar energy is the fact that it is a renewable energy source but it also bares other advantages that make it suitable for residential and maintenance reasons. Of these include the conversation of thermal energy which can be used for any heating components required for the tiny house, furthermore the electricity can be used to advance the supply of clean water by employing an efficient water distillation system. Although the maintenance costs tend to be low, it is important

Introduction In the water treatment process, there are lots of processes required in order to remove sediments, bacteria, viruses and impurities. These processes are including screening, filtration, flocculation, sedimentation, nitrification, chlorination, coagulation, and disinfection. In many municipal wastewater treatment has some standards and regulations to follow in order to distribute clean and safe water supple to citizen in their area.

There are currently several different technologies used for water disinfection. These include: Chlorine, iodine, and ozone which are chemical methods of water disinfection. Filtration, including microfiltration, ultrafiltration, and reverse osmosis, are used to remove bacteria found in water.1 Additionally, one can disinfect water using UV irradiation, ultrasonic treatment, electrolysis, solar disinfection, and slow sand filtration.2 Water-borne illnesses continue to trouble developing countries and
