4. Factors influencing the Physical Water Treatment
4.4.5 Swimming pool water
There are no typical limit values to substances in pool water that are
known to hinder the Vulcan water treatment.
However, the water in a swimming pool demands constant monitoring
and several chemicals need to be added. Vulcan significantly reduces
the scaling in and around the swimming pool, in the whole piping
system and in the filters and pumps. Therefore, once Vulcan is installed,
chemicals can usually be reduced:
Disinfection
Chlorine:
The disinfection of pool water is mostly secured by adding
chlorine (Cl). Products range from granules to liquids, tabs or sticks. The
addition of chlorine can often be reduced by up to 10-25 percent. Please
cut back step by step (e.g. start with a reduction of 10% and then raise it).
Active oxygen
is used as chlorine-free disinfection alternative. The
amount can also often be reduced. Please apply the step by step
reduction.
pH adjustor
products either reduce or raise the pH-level and control
the total alkalinity in pool water. This is added in order to rebalance the
pH which has been disturbed by the addition of chlorine/oxygen. In line
with this, the use of adjustor products can be reduced in the same ratio
to which the disinfectant product has been reduced. E.g. if you reduce
chlorine by 15% you can usually also reduce the pH-adjustor by 15%.
Pool cleaning
Pool cleaning agents are used to fight scaling on the waterline, in grids,
on tiles or the pool´s surrounding surfaces. The Vulcan water treatment
minimizes scaling which results in a much easier cleaning process
together with a reduction of cleaning agents/chemicals by up to 50%.
