Grey Water System
This projects goal was to come up with a way to save or purify water. After that, we were to have a presentation for a series of judges and hear why they thought about it. Our group wanted to go into depth in grey water. Grey water is very lightly used water like soap water, and is wasted all the time when it can be reused. Our solution was a simple change in the pipelines to send the grey water into the toilet so that it can be reused and help to save the waste of grey water.
Evidence and Content
Grey Water: Grey water is lightly used household water that comes from showers, sinks, washing machines, and other household systems. We wanted to reuse grey water because it is a waste to let it go. However, sometimes household pipes will degrade due to the varying pH of grey water.
Solution: In chemistry a solution is a mixture of two substances together regardless of the phase of the substances. Grey water is a solution because multiple substances and compounds are dissolved in water.
Ionic Solution: An ionic solution is a solution involving ions. Salt (Sodium chloride) in water (H2O) is a common example of an ionic solution because the positive and negative charge in the water attracts the charged sodium while pushing the chloride away. This is a process called disassociation.
Molecular Solution: In an ionic solution the components disassociate from each other but in a molecular solution they stay together because the molecule involved is not attracted by the ionic charges.
Polarity: Generally solvents and solutes with similar polarity are best able to combine into solutions. For instance, water and oil don't combine together because they have different polarities so the water just stays on top.
Solute: Solute is what dissolves in the solvent in a solution. Laundry detergent dissolves in the water, creating a solution.
Solvent: Solvents dissolve solutes to create solutions. Lemon juice is the solvent in which sugar dissolves to create the solution we know as lemonade.
pH: The pH scale is a scale of the basicity and the acidity of something. The scale is log-based, which means that steps up the scale vary exponentially from one another. For example, if one sample of water has a pH of 6 and another has a pH of 7, the the water with pH 7 is 10x as acidic as the pH 6. More acidic solutions have more hydrogen ions in them. Tap water normally ranges from 7 - 8 pH. Our grey water measured at around 8 pH. If water is too acidic or too basic it can be very problematic for a filtration or grey water system. Water that is acidic can react with pipes and leach metals from them which is very dangerous for household use, like in Flint, Michigan. Our system involves PVC pipes, so they wouldn't react with grey water of any pH

Reflection
I thought that this project was important. Water shortage across the globe is very important and is something that needs to be solved. I thought that our group came up with a great idea, but it definitely was a struggle to get it. Most of our time was wasted discussing and trying to figure out what our topic should be. It also turned out that this was already an idea of hat was out there which in a way ruined the originality of the idea, but it was still a good thought. I thought that my group was great and that we worked well with each other and that if we had more time, we could have really gone into further depth in this important topic.
