CLEAN WATER CURRICULUM Background Information For Teachers 5 Wastewater What Is Wastewater? Wastewater is water that goes down drains in industries, homes, and public buildings. Less than 1 percent of wastewater is waste; more than 99 percent is water. Wastewater in the HRSD service area is returned to local waterways after it is treated. In our area, treated wastewater is not returned to .

concentrations of heavy metal ions from industrial wastewater samples, adjusted to decrease (pH) with Nitric acid. Then was added 50 mL industrial wastewater which had six heavy metal ions (Ni. 2 , Pb , Zn , Cd. 2 , Fe. 3 , and Cr. 3 ) To facilitate extraction of the heavy metal ions. Stirring: vigorous shaking was applied for 10 min as contact .

For example, metals can react with many non-metals: e.g. calcium chlorine calcium chloride (Note: When naming a compound the ending of the non-metal is changed to ide) Metals can also react with air (oxygen), water and acids. Some metals
