Form 24 As a good portion of the earth's crust is composed of iron, it is common for the water in drilled wells to contain amounts of iron. In even small concentrations this iron will render the water unsuitable for domestic use as it leaves orange and yellow stains on all fixtures (sinks, bath tubs, etc.) as well as any laundry washed in this water. These stains are extremely difficult if not impossible to remove. In addition, iron in the water creates an objectionable taste and colour. Until now, domestic water treatments for the removal of iron use hazardous chemicals (chlorine, etc.) and a multitude of various filtering devises. Their initial cost is high due to their complex nature, plus their operating cost for the replenishing of the chemicals. From the inventor's own observations these iron treatment methods are not very effective on water with high levels of iron content. The inventor's have developed a method that very simply, effectively and safely removes iron from water with minimal operating cost.
