The German-based engineering company said the new MemJet product line, already available through its USFilter opeartions, had been developed to meet the strict environmental regulations and engineering standards regulating the petroleum industry.
The MemJet Petro MBR technology is based on Memcor low-pressure membranes designed to remove common petroleum industry wastewater contaminants such as suspended solids, biochemical oxygen demand (BOD), ammonia and total nitrogen, as well as turbidity, coliforms and other infectious agents in sanitary applications.
Water clarified with the Siemens MBR technology is said to produce a filtrate of less than 1mg/L suspended solids, cloudiness of less than 0.1 Nephelometric Turbidity Units (NTU) and silt density indexes (SDI) below 3.
Siemens said the MemJet Petro MBR can also be integrated with existing biological processes to ensure the most efficient, reliable and low maintenance biological process is used for each application.
This combination of biological and membrane technologies yields performance that meets all current United States requirements for discharge from refineries, according to Siemens, providing high quality water reuse opportunities that, when used as a pre-treatment for reverse osmosis processes, can also increase RO membrane life spans and process reliability.
