Abstract
The solution concerns biological elimination of hexamethylenetetramine (urotropin) in aerobic activation with acid pH. The principle of the solution consists in the fact that to the aerobic activation a carrier of growth biomass is added in the form of bodies of polyurethane foam up to 40 percent by volume of the activation tank volume. The sediment in the suspended form is maintained for at least 5 days.
