Cite three things that you learned
Its easier for a person to blow in salty pee because it makes us flow in pee higher assiduity.
The salinity affects water movement. The differences in the density of water cause currents to move.
Characteristics of water.
What do you think?
1.What impurity particles atomic number 18 larger, the one do the water to be cloudy or the one causing the water to smell? Explain
The one causing to be cloudy atomic number 18 larger. In fact they are generally larger than the spaces between the small sand grains; then they got trapped and separated out by the sand filtration.
2. What is a flocculants? What is the purpose of adding aluminum sulphate and calcium hydroxide in steps 2 and 3? Write pertinent equilibrize equations.
A flocculants is a soluble material that is added to a glass to increase the viscosity (thickness) and increase the time it takes for the glaze to settle. The water molecules being more attracted to themselves than to either the oil molecules or the molecules fashioning up the large sediment particles. When we add adding aluminum sulfate and calcium , This makes the substances immiscible; that is, it keeps the oil and the sediments from dissolving in the water
Al2(SO4)3 + 3 Ca(OH)2 = 2 Al(OH)3 + 3 CaSO4
3.



What is activated snow and why is it employ for water purification?
Activated carbon is a realize of carbon that has been processed to make it extremely porous and consequently to have a very large surface firmament available for adsorption or chemical reaction. Activated carbon used for home water treatment typically lay off either granular activated carbon (GAC) or disintegrate block carbon.
4. Since activated carbon did the best job of cleansing water, why did you waste time doing the first two procedures: bank deposit and sad filtration? Should you simply add charcoal filter?
coulomb has a large convoluted surface area upon which concentration of very small impurity particles can occur. Had the foul water been poured directly into...If you want to get a full essay, effectuate it on our website: Orderessay
