Get to know De Nora expert, Nick Armstrong, Global Product Manager for the SORB™ family of products. With 15 years of experience under his belt, he recently joined De Nora from a background in the high purity industrial water space—providing solutions for pharmaceutical, semiconductor and power plant applications all over the world. His field is one where extreme purity counts. Now at De Nora, he’s managing our SORB contaminant removal line—targeting specific contaminants, like arsenic, iron, and manganese—as well as working toward developing new approaches to address emerging contaminate concerns globally. Today, Nick brings his passion for innovation to our entire SORB™ portfolio of solutions.

Worldwide, the need to convert contaminated water sources to usable water is growing. By 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change. With De Nora’s long standing history and excellent reputation as a innovator in water treatment technologies, we have the process knowledge, experience, and capabilities to specify, install, and maintain your passive arsenic adsorption system.

Keep Your SORB System in Prime Condition
Engineers, site managers, and maintenance personnel alike understand that proper operation and minimal maintenance of a treatment facility is critical. With our process guarantee, we can ensure optimal performance of a system for many years between media exchanges. That’s where our knowledge and service offerings come in. When you are ready, we can perform a complete media changeout, arranging for everything at your site in an efficient manner. We vacuum out the exhausted media, dispose of it at a landfill, and then commission your system so it’s ready for use. Regardless of whether or not we provided your initial system, we can extend our process guarantee with our service.

About SORB 33
De Nora SORB 33® is a granular iron oxide media, specifically made for the removal of arsenic thru adsorption. Our SORB 33 systems employ a ‘pump and treat’ process that flows pressurized well or spring water through a fixed-bed pressure vessel containing the media where the arsenic removal occurs. SORB solutions are available in a range of sizes and configurations—designed to treat your specific flow rate and quality expectations.

Your media life will typically range from 6 months to 6 years, depending on water quality levels. Media usage, however, can be optimized in multiple parallel flow adsorber systems through staging, whereby each adsorber is staggered so one is operating in the latter stages of its life.

Although these systems are simple to operate, owners should consider a De Nora service agreement to support the most effective operation of the system and undertake media change-out when required.

The De Nora Commitment
With over two decades of demonstrated effectiveness, De Nora SORB adsorption and ion exchange systems can help solve environmental, regulatory, and public health water treatment challenges and is a best available technology (BAT) for many contaminants of concern. The innovation team at De Nora is continually seeking process improvements and are in a constant state of development to offer our customers even greater efficiencies.
