The process map illustrates a basic purifying system which converts polluted water into pure water.
Overall, the system has two main tanks for set up. The first one using for elimination of natural minerals such as sand, charcoal and gravel. While the other is connected to the above storage drum with a plastic tube for storaging the drinking water.
First step of the process, the lid should opened up and add water from a bottle. The rocks and minerals in the water falls down to the edge of the drum. It eliminates clean water from the hazardous materials and keeps them on the ground.
In contrast, clean water goes with the flow in a plastic tube and finally arrives in a different tank to storage. While the other tanks lid is open for resources such as dirty and unprocessed water, this drums lid is closed to keep it isolated from the dirt. This provides to storage clean drinking water.
