Largest UF-based wastewater re-use project in the world equipped with Norit X-Flow membrane technology

Norit X-Flow is proud to announce that it has received an order from Keppel Seghers, a member of the
Infrastructure division of Keppel Corporation, to supply Norit XIGA™ ultrafiltration (UF) membrane
technology in combination with the Norit standardized UF skids.

Once commissioned in August 2010, the Doha North Sewage Treatment Works (DNSTW) project in
Qatar, with a designed UF permeate capacity of 439 MLD, will be the largest UF-based wastewater reuse
project in the world. The new facility will produce high quality reclaimed water for re-use meeting
the 4-log virus removal level, which meets the highest public safety standard. The plant features an
advanced biological treatment process as well as a combination of UF and ultraviolet (UV)
technologies.

The recent win of this project in Qatar further strengthens Norit X-Flow’s leading position as a UF
technology supplier. The Sulaibiya wastewater re-use plant with a capacity of 375 MLD, which started
up in November 2004, was the beginning of a successful entry into this market. Today, Norit X-Flow
sets the benchmark in UF technology for large scale plants in wastewater re-use applications.
