TedTalk

        We finished our TedTalks yesterday! I think it went really well. Whitley and I prepared for a long time for it and we felt pretty confident, we also pretty much had everything we wanted to say memorized. We cover a lot of topics during our talk. For example, our inspiration(water is life foundation), what we learned(how to blog, how do make a blueprint, using the 3-D printer, building using many different materials, experimental testing, etc.), set-backs (hitting a dead end in the middle of the project, figuring out our prototype wasn't going to work like we thought, running out of ideas and many other things) and lastly, describing our final product and blueprint. 
     Our final blueprint looks like a long skinny tube with a open bowl at the top. The bowl will use a series of condensation to take the salt out of the water. Next, at the top of the tube, will be a series of membrane paper and a metal strainer to get the large chunks of mud or bacteria out of the water before it goes through the smaller processes. Next will be Oil of Oregano, known for its antibacterial power. After this is chia seeds which provide microbes. Next, there will be coconut skins and charcoal which give the carbon effect and take the chemical taste out of the water. Lastly, the water will come out the bottom of the tube as freshwater, this whole process will take a total of about 3 minutes. We hope to finish this project over the summer and we will post pictures on our blog!

Building the Filter

         This week Whitley and I have been making the outline of the filter on the 3-D printer. It will look like a long slender tube, with a hole at for the water to come in, and a hole at the bottom for the water to come out. We already have the Oil of Oregano, but we are still waiting for the salinity and ph filters and charcoal to arrive. Once that has arrived we will start filling in the filter. First, we will activate the charcoal and pour it in the bottom. Next we will fill in some membrane filters with chia seeds. After that, at the top will be a layer of strainer and then oil of oregano. 
We are currently having trouble with the 3-D printer, but we hope to have it fixed soon so we can start officially building. We think that we might be able to finish the filter by the time of our ted talks.

Testing

     Last week on Wednesday, Whitley and I did some testing for our desalination filter. We tested Oil of Oregano and it worked extremely well.  It is known for killing bacteria and providing strong microbes, and even without the salinity and ph testers we still could see a difference in the filtered water and the pond water. We are still waiting on the some of the materials, that are taking a very long time to ship. Next week we will start using tinkercad, which is the 3-D printer's design palette. We will just start with just the simple outline of the filter and then we will fill in the membrane filters and the other supplements.

Ordering and Creating


           Last week we finally developed our blueprint and the supplements we will need for our filter. This week, we have been researching and testing to make sure that our materials are safe and work to do the things we need them to do. We are still waiting on our order of ph testers and salinity testers. Also, we just put in our order for a strong oil of oregano to kill bacteria, and we just purchased some charcoal at the store. We have already done some testing with the membrane filter paper and we are have discovered that it seems to work better with added pressure and a little bit of coconut oil on the top.  The container we will be using will be an old, standing basketball pump, so the water can be pressurized, which makes the desalination process faster.  We plan to start testing putting together the filter next Wednesday, when we have received all of our supplements and supplies.

BluePrint Done!


        Whitley and I have officially decided on the supplements for filter and have created our revised blueprint. This is how our filter will be layered. We will be using a system of condensation to dissolve the salt, this will be the very top of the filter. Then we will have a series of membrane filters that catch the bigger bacteria particles, and large chunks of mud, dirt or other things. Next we will have Oil of Oregano, which is known for breaking down bacteria and killing diseases. At the bottom of the filter there will be activated charcoal, which is known for taking chemical tastes or non water tastes out of water. After that there will be a mesh wire in case any large particles happen to get through the other supplements. The filter will also have a pump, to get a fast result the water needs to have added pressure to help squeeze it through the supplements and filter papers.  And at the bottom will be a large bowl to collect the clean water!!

Goals and Plans

            This week Whitley and I are making layouts and plans for our construction coming up. We are also making long-term goals for the end of this project and what we will do afterwards. The ph and salinity filters are coming and should arrive next Friday. Some of our short term goals are obviously to successfully create a unique desalination filter to present in a Ted Talk along with educating some of our classmates on water related issues.  Some of our long term goals after creating the filter are to donate our filter and raised money to the organization that we choose and raise awareness for the water crisis. Once the filters arrive we will begin another round of tests. Some of the things we'll be testing will be different microbes, vinegar mixed with other chemicals such as hydrogen peroxide and other acidic ph's. After this upcoming test we will finally begin our construction.

Testing Day

                  Today Whitley and I have finally tested our theories.  We used all of the natural ingredients that we thought would work and we got pretty good results. First we took muddy pond water and tested the Chia seeds with membrane filter paper and this worked fairly well, but still left a significant amount of residue of mud.  Then we tried the potato skin and this drew out most of the salt but none of the mud. Next was the coconut oil which worked extremely well and the mud and pond water particles seemed to pool up on top of the membrane filter and not get through the paper, this left the water very clear. And last was the Pineapple, since pineapple is know for decaying meat and sometimes bacteria, we hoped it might work, but unfortunately it did nothing. We are going to run a few more tests in the upcoming weeks and just ordered a ph and salinity meter to test the water.  We also are ordering some non-harmful chemicals to help with the Desalination process and once we find out the ingredients we need we will be able to construct the filter.  
Here is a picture of the residue that pooled up on the top of the membrane filter after it went through the coconut oil.
