Saudi Aramco, the national oil company, has announced it is intending the commercialising a wastewater treatment technology in conjunction with Siemens Water Technologies, the company announced on Wednesday.

The patented EcoRight technology treats oily or industrial wastewater by using granular activated carbon in a modified Membrane Biological Reactor (MBR), says the company on its website.

Siemens has been granted a license to sell the technology, in return for royalty payments.

The EcoRight process achieves a high Chemical Oxygen Demand (COD) removal efficiency with almost no additional operating or capital costs, says Aramco.

In areas where water is scarce, the system allows for the inexpensive reuse of wastewater, thus conserving groundwater. In areas where discharges must meet strict environmental requirements, the system can provide the treatment necessary for compliance, reads the website.

Since it provides the same removal capacity as much more energy-intensive technologies, it qualifies as a green technology and can earn CO2 reduction credits.

This system can be used at all Saudi Aramco operating facilities that generate oily wastewater. Siemens has identified a number of potential uses and anticipates a five-year market for sales in the hundreds of millions of dollars with potential sales all over the world.

EcoRight is being pilot tested at Ras Tanura Refinery as a potential replacement for its waste injection well. It is part of a proposed build, own and operate proposal for the Jiddah Refinery Phase II Wastewater Treatment Upgrade Project.

Almost all other Saudi Aramco industrial facilities have some application need. The Water Management Committee will prioritize the needs of Saudi Aramco facilities that can benefit from EcoRight and schedule the projects into the Business Plan as appropriate.
