Metals Removal from Stormwater by Commercial and Non-Commercial Granular Activated Carbons Removing dissolved metals from urban storMwater may be required to protect aquatic species in particular watersheds. This research examined the adsorption of zinc and copper on 12 granular activated carbons, of which six were obtained This research examined the adsorption of zinc and copper on 12 granular activated carbons, of which six were obtained commercially and six were produced by thermal activation of agricultural byproducts in the laboratory. Batch studies were used to obtain single solute distribution coefficients at pH 7.
September 30, through May 30, Project Amount: According to the World Summit of Sustainable Development, the major reason for lack of safe water is either scarcity of water or contamination of water sources. Lack of safe drinking water is due Research paper on water purification both lack of investment in water systems and inadequate maintenance of existing systems.
About half of the water in drinking water supply systems in the developing world is lost to leakage, illegal hook-ups and vandalism.
In some countries, drinking water is highly subsidized for those connected to the system, generally well-to-do people while poor must rely on either expensive private sellers or unsafe sources. Reasons for this include shortage of water, poverty, and lack of education about the impact of drinking unpurified water.
The World Health Organization estimates that at any given moment, approximately one half of all peoples in the developing world are suffering from one or more of six primary diseases caused by poor water supply and suboptimal sanitation.
These six diseases are diarrhea, ascaris, dracunculiasis, hookworm, schistosomiasis and trachoma. The economic impact on developing countries of large proportions of people suffering from such diseases is understandably dreadful.
With an eye on developing nations, this project seeks to find sustainable, yet economically and socially practical solutions to the problems associated with polluted water.
Many techniques such as chlorination, distillation, boiling, sedimentation, and use of high tech filters have been utilized to purify water. These methods, however, face major barriers such high price, maintenance, conservation of fossil fuels, and unhygienic waiting periods.
Our proposed solution to this problem involves production of a low cost and effective water filter KlarAquawhich requires no electricity, Besides being sustainable, it is environmentally friendly, easily implemented, and easily produced by a local artisan. The system eliminates bacteria, Research paper on water purification turbidity, has strong potentials to remove other common surface and groundwater pollutants, requires no extra equipment to store pure water and its application can be tailored to regional social and cultural factors.
The main objectives of the project are to produce filters that: Can effectively remove bacteria and other contaminants from drinking water, Are easy for people to use, Are easy for local potters to produce, Have an acceptable flow rate one that will not make people too impatient to useAre of little or no cost to users, Can be easily implemented with an effective educational system, Inspire users to practice good hygiene, Inspire economic growth by promoting health and creation of jobs.
In response to this challenge, IIT's team of students and faculty proposes a low-cost ceramic water filter as a means of removing turbidity and eliminating bacteria and other pollutants from water.
With improved efficiency, decreased energy and less equipment necessary than any current portable water purification systems, the proposed filter "KlarAqua" offers a sustainable solution to the problems associated with lack of access to clean water in developing countries.
Focusing on third world countries, our goal is to allow these filters to be easily produced by local artisans and potters from local material. The team of students and faculty at HT-Monterrey Tee began this project with the notion using local clay, colloidal silver and sawdust to fabricate a filter.
Student teams were divided into three subgroups, each focusing on a specific element of the project: The composition team has begun to investigate the following three aspects: Testing has been performed in all three aspects to evaluate the most cost-effective filter composition, weighing effectiveness of filtration and flow rate against the cost of colloidal silver and the ratio of clay to sawdust.
This team has designed a product KlarAquawhich can be made entirely by the local population using local materials, without complicated industrial technology, and with a useful lifespan. The design team investigated available local materials and used information as their starting point for the design.
A derivation of common plastic containers, initially proposed for carrying water and storage, resulted in a more efficient, yet simpler design. Subsequently, the design team was able to overcome a major obstacle, the potential for the unpurified water to bypass the filter as it flows downward.
The proposed modification to such containers ensure that our product maintains cultural relevancy, sustainability and accessibility since it will resemble current water storage devices and the components necessary for production will be readily available for years to come. IIT's"s team has designed and produced a simple yet effective process to convert local materials into a water filter, which can be made and used by the average person living in the local areas in need of clean water.
The business team, in partnership with a team of students from Monterrey Tec. The rural areas surrounding Monterrey were selected as our first test market phase I pilot study.
Analysis of current water purification systems, water safety knowledge level and demand for personal-use water purification system has begun but requires further research. The marketing plan is designed in such a fashion that it can easily be modified according to the cultural factors and nuances of areas in which the product is going to be used and promoted.
For example, hospitals and clinics can be used as an education arena, since those recovering from an illness are at high risk for water-borne diseases. More educational ideas were developed as the business team gained a better understanding of its potential market.
The business team has also developed a training program, which will teach local potters and artisans how to manufacture the water purification system including manuals using pictures and graphics, written in the local language.
Upon conclusion of preliminary analysis, the team identified a need for collaboration with local leaders and NGOs in order to effectively promote the need for safe drinking water and sustainable use of the developed water purification system.
By engaging churches and political figures in our efforts to promote the health and economy of their community, more of the population can be reached and in the most culturally appropriate manner.
The project was successful and able to optimize the design of a cost effective, yet efficient, easy to produce, and easy to use water purification filter Klar. Aqua for developing and underdeveloped countries.Water, Water Purification, Filtration, The aim of this paper is to provide an overview of the properties of iron and iron minerals and their reactivity with some important inorganic anionic contaminants present in water.
It also summarizes the usage of iron and iron minerals in water treatment technology. This research examined the. This funding is being provided through the Desalination and Water Purification Research Program for the development of new water treatment technologies and Title XVI Water Reclamation and Reuse Program for research into the deployment of new technologies that supports the expansion of water technologies in new locations.
Water Purification Research Paper October 18, UsefulResearchPapers Research Papers 0 Water purification is a process of removing undesirable chemicals, biological pollutants, suspended particulate matters and gases, contaminating fresh water. Water purification is the removal of contaminants from raw water to produce drinking water that is pure enough for human consumption or for industrial use.
