Abstract: The invention relates to a method for blowing off gaseous contaminants from crude water in the production of drinking water, comprising the step of introducing the water to be treated to the top of a shielded aerator and letting it pass through stacks of tubular elements interspersed with perforated sheets, while subjected to counter current suction. In a second aspect a device is provided for blowing off gaseous contaminants from crude water according to said method.

Abstract: The invention relates to a method for preparing potable water from crude water containing trace species contaminants. The method includes the steps of separating iron compounds and optionally other compounds from the crude water, contacting the water with a ferrous material, co-precipitating trace species upon aeration, and recovering drinking water.
Abstract: A method and a device for purifying water from contaminant trace species, especially arsenic, by co-precipitating trace species during oxidation and precipitation of iron compounds with subsequent separation. The co-precipitation is improved by contacting the water with an iron-containing material prior to oxidation to increase the iron content of the water. Arsenic and other trace species harmful to health may be removed from water effectively and in a simple manner, thus being able to comply with the more restrictive limits of arsenic in drinking water.
