Materials:
graduated cylinder
4 beakers glass funnel plastic funnel ring stand filter paper stirring rod charcoal sand foul water sample rubber tubing pinch clamp iron ring plastic cup scoop Objective/Purpose: To purify a sample of foul water using oil-water separation, sand filtration, and charcoal adsorption and filtration.
Procedure: First, you have the measure the foul water sample and record it in your data table. You have to record what you see and smell before you filter anything out. Then you have the separate the oil from the water using the ring stand, rubber tubing, pinch clamp and funnel. After you have done that you record your results for after Oil-Water separation. Next, you have to put sand in a plastic cup and make sure there is a hole at the bottom. Filter the sand through the funnel and record your results for After Sand Separation. After that, you mix in some charcoal and filter it through the funnel making sure you don’t pour above the filter paper unless your experiment will be ruined. Then, record your results for After Charcoal Adsorption and Filtration and you are done.
Results:
Data Table Color Clarity Odor Presence of Oil Solids Volume (mL)
Before treatment Yellowish, brown No Garlic, yes Yes Yes 100 mL
After Oil-Water Separation Tan, brown No Garlic, yes No Yes 84mL
After Sand Separation Brown No Garlic, yes No No 67mL
After Charcoal Adsorption and Filtration Cloudy Yes Yes No No 61mL
Science Concepts & Questions:
What percent of the foul water was lost during purification? 39%
What volume of water was lost during purification? 39mL
Why does the “pure water” conduct electricity and the tap water does not? The “pure water” conducts electricity and the tap water does not because the “pure water” has dissolved such as salt in it.
What process can be used to separate the dissolved particles from the water? Evaporation
