Transcript of Water Filtration: Physics Project

WATER: FILTRATION & HEALTH madelline abourched :: physics :: spring 2011 WHAT IS WATER? tasteless colourless wet odourless solvent solid liquid gas ocean river 60%-70% of human body how much water should i drink a day? Drink 50-75% of your body weight in ounces.

inactive people: 50%
active people: 75%

150lb person
÷ 2 (50%: inactive person)
= 75oz 75oz = 4 water bottles EXAMPLE Divide 75oz by hours awake ≃16 hours 4.7 oz per hour about water bottle every hours 4 1 bottle ≃20oz Factors that influence water needs Exercise: The more you exercise, the more water you will need to drink to keep hydrated. On top of your minimum requirement, an extra one or two (8-oz) glasses for every hour of exercise should be sufficient. Environment: In hot and humid weather which causes you more perspiration and urination, drink additional glasses of water to replenish loss of moisture and to keep hydrated.
•Illnesses or health conditions: When there is fever, vomiting or diarrhea, your body loses water, which needs to be replenished with rehydration solutions. Other health conditions like urinary tract or bladder infections may also require you to drink more. Monthly Water Costs bob bob 75 oz (4 water bottles) daily x 30 days = 2250 oz (120 water bottles) Option #1 Bottled Water Dasani 20 oz @ $1.49 each x 120 monthly bottles $180 per month Option #2 purified Water x 2250 monthly oz $4.50 per month us gallon @ $0.25 each additional one time costs
reusable 3 gallon water container: $7
ceramic water dispenser: $3
reusable water bottle: $10 total $15 $20 first month is still better that $180 and the winner is..... Where can you get purified water? CVS
1. Activated Carbon Filter: for chlorine and odors 2. Micron Filter: for dust, rust, and other particles 3. Reverse Omosis: for salt and impurities 4. Post Carbon Filter: imporves taste of water 5. Ultraviolet light: to ensure safe, high quality water Filtration System
Has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities.
As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon Activated Carbon Filter : for chlorine and odors Removes:
volatile organic chemicals (VOC)
pesticides and herbicides
trihalomethane (THM) compounds
hundreds of other man-made chemicals found in tap water. Micron Filter : for dust, rust, and other particles Reverse Omosis : for salt and impurities Post Carbon Filter : improves taste of water Ultraviolet light : to ensure safe, high quality water Sediment filter which traps particles that is measures in microns with ranging sizes and shapes
Can be thin woven fabric to a pourous foam or solid porous block Removes: sand
small particals
heavy sediment
volatile organic chemicals (VOC) allows the removal of particles as small as individual ions
Uses a semi-permeable membrane, allowing pure water to pass through it, while rejecting the contaminants that are too large to pass through the tiny pores in the membrane
The most reliable and effective of all filters though cannot be used as sole purification arsenic
bad tastes
heavy metals
hydrogen sulfide
VOC’s Removes Removes:
residual Volatile Organic Contaminant (VOC) that may have carried over Enhances or "polishes" the taste of the product water. Removes: microorganisms -cryptosporidium
-giardia oocysts -bacteria
-yeast Combined with various forms of filtration
When harmful microbes are exposed to the UV rays, their nucleic acid absorbs the UV energy, which then scrambles the DNA structure of the organism
The cell is rendered sterile and can no longer reproduce making it no longer a threat. $2100 yearly savings: so why not tap water? Aesthetic Problems
These are some of the most noticeable problems; bad taste, unusual color, unpleasant smell. While being inconvenient these things won't necessarily hurt you, but they may suggest something harmful in the water.
Lead is extremely harmful to everyone and can cause serious problems, especially in infants and young children. Lead is a heavy metal that is picked up in the water by lead based service lines, plumbing in older homes, corroded pipes, soldered joints in copper pipes and brass fixtures.
Nitrate is very dangerous to young children and pregnant women. It is a common component of fertilizer and is most common in rural areas.
Organic Chemicals
Volatile organic chemicals, when ingested, have been known to cause cancer and many other adverse health effects. Organic chemicals are most commonly found in industrial and agricultural areas from pesticides and other organic compounds. Some water-chlorinization systems also have been found to cause harmful organic chemicals to be in the water, such as trihalomethanes.
Pathogens are disease causing microorganisms such as bacteria or viruses. But Hey, Why not spend less then $5 a month and not take a risk What the Bible says about water Reusable water bottles in Biblical times Genesis 21:19 And God opened her eyes, and she saw a well of water; and she went, and filled the bottle with water, and gave the lad drink. Didn't drink unpurified water Exodus 15:23 And when they came to Marah, they could not drink of the waters of Marah, for they were bitter: therefore the name of it was called Marah. (God purified it for them later in that passage) 1 Corinthians 3:16 Don't you know that you yourselves are God's temple and that God's Spirit lives in you? bpa free Overview Drink 50-75% of your body weight in ounces Buy Purified water for $.25 a gallon you can buy it at CVS where there are five purification and filtration systems your body is important, s put good things in it
we are the temple of God so we need to take care of our body drink more water!
