A common remedy for activated sludge system problems is to
increase the waste activated sludge flow rate, when would an
increase of WAS rate not be correct? - ANSWER - > When
straggler Floc is present in clarifier and settle meter
The chlorine residual is falling An inspection of the 150lb
cylinder and chlorine feed equipment shows ice forming on the
chlorine regulator and feed lines. The best method to fix the
falling chlorine residual is? - ANSWER - > Put another chlorine
cylinder online
Caution must be used when adding caustic chemical to a
digester.
Lime can combine with carbon dioxide in the digester to form
what problem? - ANSWER - > A dangerous vacuum
How many gallons will the single piston, reciprocating sludge
pump discharge per minute If the piston bore (diameter) is 6
inches and the stroke length is 11 inches? The pump runs at 99
revolutions per minute. - ANSWER - > 134gpm
solve MCRT:
Flow: 3.6mgd
, Basin volume: 5.0mg
MLSS:2350mg/l
WAS ss:4800mg/l
WAS flow: 150000gpd
Eff tss: 15mg/l - ANSWER - > 15 days
There are high suspended solids in the water applied to the
filters due to bulking sludge in the secondary clarifiers.
Polymer is used as a filter aid chemical, but the effluent ability
is worsening.
What is the best method to correct the filter problem? -
ANSWER - > Run jar tests to determine best Polymer dosage
An advantage of a continuous backwash, up flow, deep bed
sand filters is? - ANSWER - > Filters do not need to be taken out
of service for backwashing
The aeration tank dissolved oxygen has been running normal,
1.5 to 2.0 mg/L the whole month.
Today's D.O. reading has spiked to nearly 6.0 mg/L in the
aeration tank and the clarifier and plant effluent or cloudy.
What is the most likely cause of the rise in D.O.? - ANSWER - >
A toxic shock load of cyanide has entered the plant
Plant fecal coliform counts do not meet state standards.
The chlorine supply is not the problem and there is adequate
vacuum and chlorine feed the chlorine contacting has no solids
build up and the effluent flow is below design.
