Section 3

Question Answer
1&2 step of wastewater treatment 1: pass through screens filter out large solids 2: enter grit chamber, small particles settle
3&4 step of wastewater treatment 3: preliminary tank(heavy sink light float) 4: aeration tank (microorganisms added)
5&6 step of wastewater treatment 5: organisms settle 6: chlorine added to kill harmful organisms

Section 4

Question Answer
Septic system 1 bacteria in the tank break down waste
Septic system 2 solid materials settle to bottom
Septic system 3 light materials float to surface
Septic system 4 liquid layer in between floats out
Septic system 5 materials leak into soil through holes in pipes
Septic system 6 more bacteria digest and break down waste
Septic system 7 Liquid returns to groundwater supply

Section 4

Question Answer
Step 1 of Water treatment plant1.screen filter out large solids (plants, fish)
Step 2 of Water treatment plant2.holding tank add chemical make small solids settle/clump
Step 3 of Water treatment plant3.passe membrane filters take out remaining tiny solids(made of gravel, fine sand, and charcoal)
Step 4 of Water treatment plant4.chlorine added
Step 5 of Water treatment plant 5.pump to storage sites
