The document discusses how public water is treated and used. It describes that water is treated through processes like filtration, sedimentation, and disinfection to remove contaminants before being used for recreational, medical, and industrial purposes. The treatment process aims to remove solids, bacteria, compounds and convert wastewater into safe water. It also notes some common contaminants in water like arsenic, lead, and nitrates that must be removed for health.

23. Why is it Important to Clean Our Water?

24. Why is it Important to Clean Our Water?
• Arsenic
– Could cause skin damage, circulatory
problems and increased risk of cancer.

25. Why is it Important to Clean Our Water?
• Arsenic
– Could cause skin damage, circulatory
problems and increased risk of cancer.
• Lead
– Can cause various health problems

26. Why is it Important to Clean Our Water?
• Arsenic
– Could cause skin damage, circulatory
problems and increased risk of cancer.
• Lead
– Can cause various health problems
• Nitrate
– In drinking water at levels above 10ppm is a
health risk for infants younger than 6 months
of age. High levels of nitrate in drinking water
can cause blue baby syndrome.

30. General Wastewater Treatment

31. General Wastewater Treatment
• All water treatments involve removal of solids, bacteria,
algae, plants, inorganic compounds, and organic
compounds.
– Removal of solids is usually done by filtration and
sediment.
– Converting used water into environmentally
acceptable water is wastewater treatment

• Charcoal is used to remove the color of raw sugar from
various sources.
