Term 1 of 49
How do you get rid of chloramines?
you super chlorinate
liquid filter acids
when flooded
orp and ph
Term 2 of 49
What is oxidation reduction potential (ORP)?
qualitative measure of chlorine's work value (how well it's working)
an indicator of the presence of heavy metals in the water
a measure of the temperature of the water in the pool
a quantitative measure of the total chlorine concentration in water
Term 3 of 49
What is the maximum spa temperature and for how long?
104 degrees for 15 minutes
because calcium carbonate is more likely to form on elevated temperatures
the chemical process that kills or deactivates pathogens
dissolved in water ph 13+
,Term 4 of 49
What are polymers?
liquid filter acids
cloudy turbid water
orp and ph
digest body fluids and oily polymers
Term 5 of 49
What does sanitation do?
absence of microbes
inhibits bacterial growth
destroys bacteria
without infection
Term 6 of 49
What is the most influential variable in the CSI?
pH
Teaching Lessons
Special pools
wear protective equipment
Term 7 of 49
What is total Alkalinity?
this is an index of the water's resistance to pH change
this refers to the temperature stability of the water
this measures the total amount of dissolved solids in the water
this indicates the presence of harmful bacteria in the water
,Term 8 of 49
What does eliminating dead spots mean?
Water is removed from the pool to create more space
Only the surface water is heated while the rest remains cold
Water is circulated only in one corner of the pool
Heated and treated water is equally distributed in the pool
Term 9 of 49
pH of soda ash
dissolved in water ph 12+
dissolved in water ph 23+
dissolved in water ph 3+
dissolved in water pH 13+
Term 10 of 49
When do you backwash?
Only when the pool is empty
When the water temperature exceeds a certain level
After every swimming session regardless of pressure
When the pressure differential indicates it is needed
Term 11 of 49
How do you calculate how many gallons are in a pool?
1. calculate the volume (LxW)xDavg
2. multiple by 7.5 gallons
multiply CC by 10
When the pressure differential indicates it is needed
qualitative measure of chlorine's work value (how well it's working)
, Term 12 of 49
What is the most important factor related to pool water chemistry?
104 degrees for 15 minutes
HOCl
650mV
pH
Term 13 of 49
Horizontal High Rate Sand Filter
decreases surface area
destroys organics
increases surface area
decreases surface energy of enamel
Term 14 of 49
What do enzymes do?
destroys bacteria
liquid filter acids
digest body fluids and oily polymers
destroys bacteria
Term 15 of 49
When are chloramines formed?
during the winter months when pool usage is low
when water is treated with ozone instead of chlorine
when chlorine levels are excessively high and organic matter is minimal
under a heavy organic load with low chlorine levels, often with limited air movement
