true -
Is chlorine heavier then air
you contact the fire department in the event of this -
who do you call when you have a chlorine leak
ammonia soaked rag or swab held near the suspected area -
what is best to use when looking for a chlorine leak
milk -
in case of exposure to chlorine what is best to consume
Hydroflouric Acid -
what is very strong acid
short circuit -
what you get when you don't have good mixing
permanent hardness -
non carbonate hardness
hours -
Flash mixing is seconds, Flocculation is minutes sedimentaion is .....
detention time -
in coagulation process this is not impossible but in Flocculation it is. ...
service , backwash, brine, rinse -
correct order for Ion exchange
, in bicarbonate form -
when there are no pheonlphthalein alkalinity present in the sample then you can assume that it is in
what form.
pure blue -
the titrate turns what color when measure the hardness EDTA
too high carbon dioxide dose reducing PH and causing Cal and MG to dissolve back in solution -
hardness is as high as raw water coming from Lime Softening. what could be the problem with the
LS process
temporary hardness -
with enough lime added MG carbonate becomes MG hydroxide
ph is nearing 11.3 -
MG bicarbonate converts to MG carbonate when....
ph is rising towards 10.2 -
to get calcium to supersaturation add more lime. convert the CA bicarbonate to CA carbonate
ph is rising towards 8.3 -
adding carbon dioxide
not high enough -
short circuit may indicate that the Flocculation mixing is ....
Detention time -
slowing the flow down in the plant can increase what
turbulence,
Floc
