Need and Goa Need and Goa oal Statement: oal Statement: Contaminated Well Water Scope of Evaporated project Solution Contaminated De-watering Waste Peltier solution Water Disposal Desalination System Solid Purified waste Water (for Water (for use) Need: The Peltier Desalination System ne needs an efficient and reliable method of disposing of the contaminated w waste water solution. Goal: To build and test a scale model of th f the system that receives a concentrated solution of contamina nants, boils away the excess water, and removes solid waste from the sy system. Changes: No changes to overall scope

Specifications for Specifications for for Scale Model for Scale Model • Must do: Quantitative Qualitative • Handle 10 gallons of contaminated • • Receives contaminated water from solution per day P Peltier Desalination System • Footprint - 12x18x12in • Removes the contaminants from the • system s • Moisture content less than 1% • Moisture content less than 1% • Vent steam (contaminants) away from • Vent steam (contaminants) away from • • t the pure water • Cost less than $2000 • Powered by standard household outlet • • Should do: • At least 2 year maintenance lif life • Weigh less than 100lbs • Would be nice: • Seals bag for easy disposal • Scale model connects to Peltier ier Desalination

Problems an and Solutions Problem: Short heater wires res interfere with tank rotation Solution: Tech shop staff ad added a wiring terminal and extended flexible le wires.

Problems and Problems and and Solutions and Solutions Problem: High moisture con ontent of salt Solution: Heat the system fo for a longer time Caveat: Heating causes sa salt to harden and adhere stronger to the cyl ylinder
