Arsenic-Free Water Filter


Problem and reason for project selection

Arsenic poisoning from well water is an immense problem that is well documented as well as mind baffling. Tens of millions of individuals living from the foothills of the Himalayans to the Ganges delta are aggrieved by an unrelenting natural disaster that cripples both their physical and mental capabilities (Smith, Elena and Mahfuzar, 1095). Drinking arsenic water for long periods of time can result to cancer in the lungs, skin, kidney and bladder. Elevated risks of lung cancer have been noted at exposure levels of up to more than 750 (µg/m3) in a year (Ferreccio, Claudia and Guillermo, 674). Previous filtration designs have illustrated a simplified, less expensive and reliable method of using electrolysis to eliminate arsenic from contaminated water. Nonetheless, in this project, it is our desire to convert this concept into a product that be manufactured.

Project brief

In response to the above problem, this project proposes a low cost arsenic water filter as a way of eliminating arsenic from water. With enhanced efficiency, minimized energy and less equipment required than any current portable water purification systems, this proposed arsenic filter will offer a sustainable solution to the problem that arise from poor access to clean water in a lot of countries. This project is expected to run from January 10th 2017 through to August 10th 2017. Numerous techniques such as distillation, chlorination, sedimentation, as well as use of high tech filters have been employed in water purification efforts. However, these methods encounter major obstacles such as elevated price, maintenance, unhygienic water periods and conservation of fossil fuels. The proposed solution to this problem in this project involves the manufacture of a low cost and effective water filter which does not require electricity. In addition to this filter being sustainable, it is environmental friendly, easy to implement and also easy to manufacture. The feasibility of this project being successful is very high since this project is founded on already known knowledge as it builds on previous filtration designs that demonstrate an easy, less expensive and reliable way to eliminate arsenic from water. This project is estimated to cost approximately 10,000 US Dollars.

Project specification

The objectives of this project include designing, field testing, preparing for manufacture a well built, efficient, and reliable arsenic removal filter for use in arsenic afflicted areas. This project also aims to verify and document the operation and efficiency of the arsenic water filter with regards to robustness, longevity, simplicity as well as affordability. This is concurrent with the primary goals of the project to manufacture filters that can efficiently eliminate arsenic from drinking water, easy for individuals to operate, easy to manufacture, have an acceptable flow rate, less expensive to users, as well as inspire users to promote good hygiene. For this project to progress and become successful there are facilities and knowledge areas required. The required facilities include a machine shop, a chemistry lab, and a project lab. The knowledge areas necessary for the success of this project include chemical engineering, engineering graphics, environmental engineering, machine design, modeling and optimization, product design, and project management.

Ensure that all the necessary equipment has been purchased and that all the important knowledge areas necessary for the project are available.

The environmental engineer and the chemical engineers examine different samples or arsenic polluted water, the arsenic pollution level, and suggest a way how knowledge from reverse osmosis system can be applied in manufacturing of an arsenic water filter.

The project manager ensures that all relevant information is passed to the engineering graphics specialist and the machine design specialist.

The machine design and engineering graphics specialists use knowledge form previous filtration designs to manufacture a sample arsenic water filter.

This newly manufactured sample of an arsenic water filter is taken in the field for testing to determine its efficiency and reliability.

If faults were discovered during testing, they are addressed and the sample is tested until the desired outcomes are achieved, and the many more arsenic filters of a similar design are ready for manufacture.
