How is pH measured ? - ANSWER-pH is measure with with
standard electrode that is typically calibrated using pH buffers
When finding concentration of TS by evaporating water at 103-
105 C the residual remains. Remains are put through filter and
separate TS and FS. After you put TS in 550 C sperates TS into
FS and VS. the FS remain while VS burn away. Between FD and
VS which is organic and which is inorganic ? - ANSWER-FS =
inorganic
VS = organic
When finding TSS by evaporating water at 103-105 C the residual
remains. Remains are put through filter. After you put TSS
residual in 550 C sperates FSS and VSS. the FS remain while VS
burn away. Between FSS and VSS which is organic and which is
inorganic ? - ANSWER-FSS = inorganic
VSS = organic

When finding of TDS by evaporating water at 103-105 C the
residual remains. Remains are put through filter. After you put
TDS in 550 C sperates FDS and VDS. Between FDS and VDS
which is organic and which is inorganic ? - ANSWER-FDS =
inorganic
VDS = Organic
Generally speaking what is the goal of wastewater ? - ANSWER-
To remove the TSS and VDS
How are settleable measured ? - ANSWER-Measured in volume
with a Imhoff cone, and not weight.
All settleable solids are TSS ? - ANSWER-Yes all settleable
solids are TSS but not all TSS are settleable.
What is the purpose of primary clarifiers ? - ANSWER-Removal of
TSS
, 3|Page
The Imhoff cone test is used to monitor what ? - ANSWER-
Monitor the efficiency of of primary clarifiers
What percent of TSS should be removed from primary clarifiers ?
- ANSWER-95%
Draw the Solids Schematic?Awnser is on pg 17. What is included
? 5 words and 11 abbreviations - ANSWER-(Incineration: VS, FS)

TSSnon)
What are the 3 gasses associated with with waste water
treatment ? - ANSWER-1. Hydrogen sulfide
2. Methane
3. Carbon Dioxide
What is the H2S? - ANSWER-hydrogen sulfide
What are the 7 apparent characteristics of hydrogen sulfide (H2S)
? - ANSWER-1. Toxic: high concentration kills
