Effects
of Iron
Iron causes ugly yellow, orange
or brown rust stains on your laundry, sinks, tubs and toilets.
It can also give water an unpleasant taste and smell which lingers on
laundry and spoils food and beverages. Manganese
leaves ugly black stains on your bathroom and kitchen fixtures.
Sulfur is identifiable
by its distinctive "rotten egg" odour and it too causes staining
as well as corrosion issues. Problems caused by iron, sulfur and manganese
can occur individually or together.
How
the Greensand Filter Operates
As the water passes through the filter bed, it
comes in contact with oxygen-charged manganese greensand. This causes
iron, manganese and sulfur to oxidize into particles which can be trapped
in the filter bed. Eventually the manganese greensand loses
its oxygen charge and regeneration is necessary. The
filter bed is cleaned and then a measured quantity of potassium permanganate
is drawn from the feeder through the filter bed, recharging it with oxygen.
Two rapid rinses ready the bed to filter your water again.
