Passavant-Roediger to use patented sludge digestion technology in new major waste water project in Iraq

Under the terms of the contract, Passavant-Roediger will design and build the sludge treatment system of the WWTP based on anaerobic sludge digestion, including energy recovery and generation from biogas. It will install twelve sludge digesters each with a capacity of 3,400m³ all equipped with the propriety Passavant-Roediger Sequential Gas Lance Mixing System.

Passavant-Roediger's patented anaerobic sludge digestion technology reduces sludge volumes and renders it harmless for safe discharge. It also allows the recovery of energy from the organic matter it treats. The process involved can generate up to 80 per cent of the power requirements of a WWTP.

Commenting on the award, Dr. Mazen Bachir, Managing Director of Passavant Roediger said, "We are pleased to have been selected to contribute to the redevelopment of Iraq's vital infrastructure. Our global experience and patented technology will allow the implementation of an optimal treatment process tailored to the sophisticated requirements of this high- scale project. Our modern digesters will guarantee energy saving operations and less consumption of chemical substance required for the treatment process while ensuring efficiency and long term profitability for the client. We are currently gearing up to mobilize on site shortly and we expect the project to be delivered in 2013".
