For my experiment Filtration vs Distillation my goal was to find a solution that would help those who lack access to clean drinking water. The solution I was looking for would help provide access to clean water to different groups of people. For example, it could be used by backpackers trekking through the woods as well as impoverished communities who are lacking access to potable water. To do this I compared two different water purification techniques. The two different types of water purification I compared were filtration and distillation. For filtration I used a physical ceramic micro-porous filter that prevents contaminants larger than 0.2 microns from passing through. The filter also has a carbon core that works by trapping chemicals and through adsorption. To distill water I boiled the water and then condensed the steam into a separate container. This process works by leaving heavy metals, bacteria and other impurities in the original water source. I collected raw/untreated water samples from two different sources, Beaver Lake and Lost lagoon. They are both freshwater sources in Stanley Park. To compare the two different water purification techniques I tested the pH levels of the water, the heavy metals ppm, the TDS ppm and I conducted an unbiased visual test of the water. I found that distillation provided the best results, but filtration may be the most practical solution for those lacking access to clean water.
