Water Filter Design Concept

When clean sawyer filters only need 1 to 2 psi of pressure to flow freely.

Water filter design concept.

Locally manufactured ceramic filters have traditionally been used throughout the world to treat household water. More thorough filtration can be achieved with a slow sand filter or reverse osmosis. In this project filtration for point of use water treatment was studied as an alternative method of water treatment for nepal. We set up coffee filters containing sand stones and then just plain filters.

A low cost water filter can serve as a subsidy such that every family can take advantage of this luxury. Students are asked to design methods to filter water using ordinary materials while also considering their designs material and cost efficiencies. Chlorination or solar distillation is highly recommended to complete i e. Currently the most widely implemented ceramic filter is the potters for peace external design.

We carefully poured the same amount of water through each filter and observed the results. The filter is flowerpot shaped holds about 8 10 liters of water and sits inside a plastic or ceramic receptacle. In this thesis literature reviews on existing water filters have been completed and design of a dual level water filter with ceramic and activated carbon is developed. Set up an experiment where the conditions.

As the fibers collect particulates the pressure to move water through will increase as the particulates create barriers to water flow. They learn about the importance of water and its role in our everyday lives. The great thing about this experiment is that you can design it however you like. A disinfection step e g.

Sawyer filters have very strong fibers see fiber strength study and are capable of handling up to 40 psi pounds per square inch of pressure. Water filter activity 1. Ceramic filtration cdc pdf pdf 2 pages. Filtration is one of the most effective yet simplest water treatment processes.
