PREASSURE PIPE END CHAMBERS


GOOD TO KNOW
Pressure pipe end chambers are normally planned with a base with a rising channel, in order to reduce turbulence and H2S corrosion of concrete chambers. PE is absolutely chemically resistant to H2S and thus allows other solutions. The pressure pipe is connected tangentially and higher than the outlet at the chamber. Strong turbulence is effected by the altered positioning of the inlets and outlets, thus assisting the outgassing of H2S in the pressure pipe end sump.

This results in a reduced H2S load and thus a decrease in unpleasant odour and concrete corrosion downstream. In addition to that, the swirling in the chamber enriches the waste water with oxygen. If necessary, the H2S loaded waste air may be purified using ROMOLD Active filters.
PREASSURE END CHAMBER TYP ROMOLD
Stagnant waste water in pressure pipe end manholes according to ATV A 157 often causes severe corrosion problems, for these buildings are commonly constructed from traditional materials. PE is chemically resistant to H2S, allowing manholes to made made in accordance with ATV design - without corrosion problems and with service life up to approx. 100 years. The integrated, bright, corrosion-free steps meet national safety requirements.

PREASSURE END CHAMBER TYP ATV
 
INNOVATIVE DESIGN MEETS STATE OF THE ART MATERIAL
CHAMBER BASE DN 1000 - RISING, STRAIGHT MAIN CHANNEL
ROMOLD Activ filter for eliminating odors.
The easy-to-install filter unit fits into any standard shaft with cone opening DN 625. Installation option even for smaller and larger diameters (59.5 to 64.5 cm).
For manhole shafts with normal H2S pollution, it can be assumed that the activated carbon has a lifetime of up to five years.
