Our Learning Trip about Process of Water
An innovative technique has been proposed for treating and purifying wastewater, which could spare budget-strapped municipalities some of the expense of handling the sludge that remains after treatment. Researchers say it could reduce the amount of leftover sludge by up to five tons a day for a plant that serves 100,000 people.
Normal activated sludge treatment in common use throughout the world involves the use of bacteria that help purify the water by eating harmful organic pollutants. However, this can leave behind tons of decontaminated sludge that then must be disposed of, often in landfills. Some of the "excess sludge," as it's called, is biomass waste, which is created by the growth of the pollutant-eating bacteria.
What is sludge?
Whatever you pour down the drain is accumulated in a tank (a septic tank is an example). The material that settles out is sludge. Municipal sludge comes out of private homes, hospitals, businesses and industries, and sometimes the storm drains.
Isn’t sludge treated?
Municipal sludge is typically treated by drying and adding lime before it is land applied. Larger contents are screened out and sent to a landfill. But sludge applied on farmlands may still contain objectionable things.

Background Knowledge about Water. (:
"Earth is the water planet.
Water covers 70% of its surface and 100% of its future.
Yet we are confronted with the paradox of water being both the source of life and also a major conduit for disease.
Around the world, some 6,000 people, a majority being children, die every day from water-borne diseases.
EPA and its partners are committed to reducing the toll from water-borne pathogens and other contaminants in our drinking water.

top 9 tips to Conserve Water !!
Hey people, we're here to give you people out there some very interesting tips and facts about water conservation:) we give you ten new tips everytime we post^^
#tip1:
Turn water off while brushing teeth and shaving; save 30+ gallons/month.
#tip2:
Shorten shower by 1-2 minutes and save 200+ gallons/month.
#tip3:
Use a low-flow showerhead, & over its 20 year.
#tip4:
Put a plastic bottle full of water or install a toilet tank dam in your older toilet tank & save 1000+ gallons/year.
#tip5:
Maintain a lawn height of 2 to 3 inches to help protect the roots from heat stress and reduce the loss of moisture.
#tip6:
Fix leaky faucets. Most can usually be repaired by replacing the washer.
#tip7:
Buy water efficient clothes and dish washers. Run with full loads.
#tip8:
Replace more lawn with no care shrubs, perennial gardens, rock gardens, etc.
#tip9:
Rain water is better than city water is for lawns. Established lawns do not need much (if any) watering to survive.
#tip10:
Install a low-flow toilet, & save up to 22,000 gallons/year ($100+). They work as well as older toilets. Check toilets for leaks by placing a few drops of food coloring in the tank. If after 15 minutes the dye shows up in the bowl, the toilet has a leak. Leaky toilets can usually be repaired by replacing the flapper.
