Sodium hypochlorite is used as a - ANSWER Liquid
1
,Suspended Solids (SS) - ANSWER Anything that settles to the bottom of the receiving wa-
ter and smothers living things
Oils and Grease (O&G) - ANSWER Anything that will float on top of receiving and pre-
vents oxygen from being added
Total solids = suspended solids & WHAT? solids. - ANSWER Dissolved
Grease entering a waste water treatment plant is removed by - ANSWER Skimming
Biochemical Oxygen Demand (BOD) - ANSWER Anything that consumes oxygen prevent-
ing fish etc. from getting oxygen they need
No industrial facility shall discharge to a POTW a waste stream with a pH lower than - AN-
SWER 5.5
Suspended Solids are removed by - ANSWER Settling
Oils and Grease are removed by - ANSWER Skimming
To determine the amount of organic material present in an industrial waste stream you
would use - ANSWER A BOD test
BOD is removed by - ANSWER Aeration and microorganisms
Valves used to open or close only are - ANSWER Ball valves (small piping)
Gate valves (large piping)
2
,Along with the SS, O&G and BOD POTWs also prohibit the discharge of - ANSWER 1. Any-
thing creating fire/explosion hazard
- worker safety
2. Anything with pH below 5.0
- acidic water dissolves concrete piping and tanks
3. Anything that obstructs flow or is a solid. - clogs piping and restricts flow
4. Anything above 104 F
- kills organisms and bacteria
5. Anything creates toxic gas
- worker safety
6. No priority pollutants Toxic Organics TTO's
- kills organisms and bacteria
7. No heavy metals
- kills organisms and bacteria and contaminates settled solids
Biomass or biosolids - ANSWER A clump of organic material consisting of living organisms
feeding on wastes and other debris
Pulp and Paper Industry - ANSWER High BOD, COD and suspended solids
Mesh equals the number of holes - ANSWER Per inch
Battery Manufacturing - ANSWER Lead and Acids
Slurry - ANSWER The suspension of water and another solid material that does not dis-
solve i.e. lime slurry
3
, Petroleum Industry - ANSWER High suspended solids, dissolved solids and oils
Gate valves are most commonly used for - ANSWER Lime slurries
Blinding - ANSWER When a screen type filter clogged because all it's pores are plugged
up
Turbidity - ANSWER Measurement of the cloudiness of a water stream. Typically, this is
due to suspended or colloidal solids and they won't settle because they are so small
Iron and Steel Industry - ANSWER Toxic organics, dissolved salts, oils, acids and solvents
Volatile - ANSWER A substance i.e. methanol gasoline that can be evaporated at a rela-
tively low temperature
Dairy Industry - ANSWER High BOD and suspended solids
Plastics Industry - ANSWER High Temperatures, oils and coolants
Because lime slurries need to be vigorously agitated or the lime will settle out and clog eve-
rything, there's only on type of pump used - ANSWER Centrifugal
Tanning Industry - ANSWER High salts, high BOD, suspended solids
Meat Packing Industry - ANSWER High BOD and suspended solids
Air stripping - ANSWER The removal of volatile organic compounds (VOCs) from a water
stream by evaporating them and adding them to air
