WATER TEAM

ABSTRACT

• At the Center for Sustainability there is going to be a need of 60 gallons of water per day for agricultural use, drinking, and other basic needs. From this information we have decided to use two slow sand filters with a water catchment system stemming from the roof for drinking water. We will tap into the Penn State water line, as a second source, incase of low amounts of rainfall.

SLOW SAND FILTER• Materials

• Process

• Output

• Oxygen and organisms in water pass through sand.

• Biofilm forms in top layers of sand.

• Through biological action and sand filtration, pathogens are rendered harmless and viruses are removed or inactivated.

• Does not require chemicals or great amount of energy.
