1.3 Selection of filters and installation
1.3.1 Filter charateristics
Fluidra recommends that the filtration system should filter at least 50% of the water from the surface of the pool as well as
50% from the lower levels of suction. The maximum turnover time for a publice pool should not exceed 4 hours, and for
semi-public pools 6 hours. In case of publice pools for children the turnover should not exceed 1 hour. The times will vary
from state to state and all local and state codes must be satisfied when using any filtration system.
Example:
If we have a public pool with a capacity of 15,000 gallons we need a filter capable of filtering this water in 4 hours:
15,000 gal/ 4 hours = 3,750 gal/ hour or 62.5 GPM
To obtain a high quality water filtration we recommend that the filtration velocity should comply with the following:
Water parks 10 GPM/ Ft² Commercial Pools 15 GPM/ Ft²
62.5 GPM/ 10 GPM/ Ft² = 6.25 Ft² of filtration area required
Now choose the filter or filters that meet this requirement. Remember it is possible to add filters together to obtain the
correct amount of filtration area required. It is also a good idea to oversize the surface area required by 10% or more, this
will allow better water quality. Whenever possible use more than one filter in conjunction, this will allow one filter to be
serviced while one is still functioning.
When sizing the plumbing for a filtration package be sure to keep in mind that the velocity of the water pipes is very
important. Each state or country may have different maximums for velocity in the plumbint. The recommendations of
Fluidra are as follows: the return line should not exceed 10 ft./ s and the suction line should not exceed 5 ft./ s.
1.3.2 Installation characteristics
To insure the correct pump size, the required flow must be obtained by taking the system head into consideration. The
system head is the added difficulty to move the water through the system presented by using elbows, piping, tees,
changes in elevation, etc. Normally,
60 ft. of water (60’ of head) is sufficient but will depend upon each individual system.
It is advisable to use the same number of pumps as filters, each pump producing the required flow for one filter. It is also
recommended that the discharge from each pump is brought together in a single manifold to the filters. This will allow
greater rates for the backwash cycle.
For each suction side, it is also recommended that the supply to each pump come from either a general suction manifold
or balance tank. The should be taken from both the surface and from the bottom of the pool.
