  Active Poly Floc
Designed for Swimming pools and Spas
·
Remove cryptosporidia
and giardia oocysts, much higher performance than PAC
·
If you don’t use a
flocculent you are not removing oocysts and the public are at risk
·
Reduces bacterial levels
by starving them of food
·
Improves water clarity
·
Reduces chlorine demand
and formation of trichloramine and THM`s
·
Easy to use supplied as
a liquid to be dosed into the water before the filters
Water clarity depends upon the performance of the
sand filters. Sand will remove particles down to 15 microns, however if
AFM (Active Filter Media) is used you remove particles down to 5 microns
and below. The infectious eggs of cryptosporidia and giardia measure 4
microns, and they are not easily killed by chlorine, chlorine dioxide, UVc
or ozone, the only really effective way of controlling the organism is by
filtering them out of the water. Sand in sand filters will not remove the
oocysts, they will pass straight through the filter bed unless a good
flocculent is used. AFM removes smaller particles and resists worm hole
channelling, so it is a much more effective barrier and when used in
combination with APF. Virtually all of the solids down to 1 micron and
even the sub-micron particles that give water a grey appearance will be
removed.
APF has been designed specifically for swimming pools and Spas
the flocculent has a much wider spectrum than simple PAC so it will
improve the water clarity and provide you with extra protection and
safety. When APF is used in combination with AFM, particles down to 1
micron, and a much higher percentage of the eggs of cryptosporidia and
giardia will be removed.
Cost of Treatment
·
For a typical 25m public swimming pool the
cost of treatment is £0.69 per day.
How to use
·
APF should be dosed into the water before a
DZA (Dryden Zeta Activator) unit, alternatively inject APF before the
filter pumps. The injection point should be after your chlorine and pH
monitoring points.
·
The application rate is 10ml to 20ml per
100 cubic metres of water per hour pumped to the filters.
Notes
·
MSDS data sheets available from
www.AFM.eu and supplied with APF
·
DZA = Dryden Zeta Activator, flocculants
work because they drop the zeta potential of solids. The DZA is a
special mixer, which amplifies the performance of the APF and NoPhos, so
you need less of the chemicals to work
·
AFM (Active Filter Media) dramatically
improves the performance of sand filters.
·
Dosing pumps available from Dryden Aqua
·
Supplied in 25 kg drums, volume 20.8
litres, order quantity is 4 or more drums
