THE RECIRCULATION SYSTEM
functions
transportation system
circulation of water
minimum time
proper dilution and prohibits development
pool recirculation pump
to move wtaer
pull, push water through filter
typical: centrifugal pump
adequate size
main pool: every 6 hours
not more than 2 hour
role of the pump
remove dust, dirt, debris
size: time of running pump
1 hour every 10ºC
ensure circulating, filtration of pool
running and circulating prevent problems
Principles of Swimming Pool operation
Filteration
removal of particles
Disinfection
feeding chemicals and control pH
Recirculation
recirculation and distribution of water
treat water and make safe
The Water Treatment System
Hydrochloric ( Muriatic ) Acid - To lower the high PH value
Sodium Bi Carbonate - To increase the low PH Value
PH Value maintain at 7.4 to 7.7
Chlorine applied as a Disinfecting Agent
Chemical Treatment is applied
The inlet Distribution System
Obtain flow of filtered and treated water
Location and sizing of inlets
Manner of re - entry is governed
Provide rapid dispersion of treated water
Filter Plant
remove by sand filters
backwashing at 8-10 psi from clean
fine-particle removal is accomplished
