EXAM 2 Ch. 9 Water Purification questions with verified solutions
1. sewage reduces spread of pathogens, reduces inorganic/organic materials to
manage- ment level that no longer supports microbial growth
2. waste- reduces organic and inorganic materials to a level that no longer
water supports microbial growth,
manageme
nt wastewater, screening, sedimentation, sludge is anoxically digested,
soluble liquid is oxidized, disinfection, and treated to effluent stream
3. wastewater
treat- ment
process
4. water purification purifying water to drink, sedimentation basin settles out large
particles, filtered through sand, disinfected with chlorine
5. indicator coliforms (gram -, rod, facultative anerobic) and fecal streptococci
