The use of disinfectants is often not enough to
produce transparent, crystal-clear water. Using
flocculants encourages and facilitate the filtration
process by making very small particles filterable
when they otherwise would not be. Using a
flocculant therefore helps to make the water crystalclear, transparent and bright.
The swimming pool water frequently loses its
transparency and appears cloudy as a result of:
Algae and bacteria
Calcium and magnesium salt precipitation
Dust carried by the air or bathers
Oxidation of iron and manganese salts
Organic and colloidal substances
In most cases, the particles added to the water
are extremely small or micro-dispersed and do not
become large enough to be captured by filtration
systems. Flocculants improve the capacity of
particles to join together and form larger, more
filterable aggregates. Colloids normally tend to
reject each other due to the electrostatic loads found on their surfaces. Flocculants neutralize these
loads, allowing aggregates to form, which can then
be captured by the filter.
Flocculants are divided into two categories:
• ORGANIC – these are made up of polymer
molecules that act as coagulants. Ideal for rapid
filters and slow filters
• INORGANIC – these are made up of
water-soluble salts of transition metals. Ideal for
slow filters
HOW THE FLOCCULANT IS USED
By injecting it into the recirculation line
Using a feed pump, inject 0.5ml of Flocculant for each cubic meter of the recirculation flow, prior to the filter entrance or in the compensation pool.
In the Skimmer
Put the amount of Flocculant in tablet form needed directly into the skimmer (from 1 to 3 tablets every 100 cubic metres) or liquid (0.5l/1ml /m3).
Flocculants are not used for diatom, sock or cartridge filters, while they are suitable for sand and glass filters.
HOW FLOCCULANTS ARE USED
Inject it into the recirculation line
Use a dosing pump to inject 0.5 ml of flocculant per cubic meter of recirculation flow, before to the filter inlet or in the balance tank.
In the Skimmer
Put the required number of flocculant tablets (from 1 to 3 tablets per 100 cubic metres) or amount of liquid (0.5–1 l/m3) directly into the skimmers.
Flocculants are not used for diatomaceous earth, bag or cartridge filters, while they are suitable for sand and glass filters.
