growth (i.e. chlorine is toxic). Regulations usually require
there be residual chlorine when water reaches your tap.
Typically, the residual concentrations of chlorine in
household water range from 0.5 to 1.0 parts-per-million
(ppm). Chlorine and Chloramines can foul and destroy
most softener resin. Aquathin chooses a high capacity,
very chlorine resilient resin to assure efficiency.
Sediment
Very high sediment concentrations can affect the resin
media, control valve and meter. In areas with very high
sediment concentrations, it may be necessary to install a
separate filter unit ahead of the water softener. Consult
your local Authorized Aquathin Dealer.
Iron
Iron concentrations greater than 5 mg/l can degrade over-
all system performance. If your water supply has iron
concentrations above 5 mg/l, pretreatment is recom-
mended.
If piping is clogged with iron, install a separate iron filter
unit ahead of the water softener.
Hardness and More
Two thirds of the water on earth is groundwater. As it
travels through rock and soil it picks up particles of cal-
cium, magnesium, iron, lead, and other minerals. For
85% of the country, that translates into "hard water".
"Hardness" refers to the amount of calcium and magne-
sium in the water and is measured in grains per gallon
(gpg).
Most of the problems associated with hard water are eco-
nomical in nature. Hardness causes unsightly soap scum
on fixtures, water spots on glasses and whitish scale de-
posits in your tubs and showers. Hard water means you
use more soap and cleaning agents because they first
have to "clean" the water before they clean anything else.
