water treatment blog

1. To treat water and filter the water there are several different processes. one way is they run the water through a sereis of screens. another is to run it though a certain rock (like charcoal) to cleanse it and than backwash it. they also would put a series of grates in the holding tanks to further filter it. the most interesting thing is how they would add several chemicals to enhance the process.
  they would add three different chemicals to the water.one was chlorean, they would add this to clean and kill the bacteria and other harmful toxins. the second chemical was phosphate they did this to coat the pipes to reduce run off from the metal. for example if little kids are exposed to lead it can lead to several deformities. the last chemical they added was flouride to make childrens teeth and bones stronger. also the lab was pretty interesting. they had to know several chemistry laws and rules to test things which adds a whole other side to how the water is treated.

how is water filtered

1.Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane.Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules. This is the reverse of the normal osmosis process, in which the solvent naturally moves from an area of low solute concentration, through a membrane, to an area of high solute concentration.
2. water is filtered by removing toxins and waste from the water purifying it from the solids that were once in it
3. a) how long does it take to filter a gallon of water
 b) what is the best method for filtering water

2.  yes for young adults like our selves this site can be used as a great resource but for younger kids it may be confusing
3 Your estimated greenhouse gas emissions are 68 tons of carbon dioxide (CO2) equivalent per year, which is above the U.S. national average.
4 a. purchase more efficient appliances and lighting watch our food control and waste less water
b. my school could recycle more things such as paper and bottles buy, efficient lighting, and conserve food
c. carpool and save emissions on co2 output create more recycle centers, and control our waste
5 the water shed is affected by everything we do. when we drive around or waste products we pollute the water which all comes back to us. so we could recieve acid rain from all the pollutants. also all the pollutants left on the ground will leak into the ground water
