Lab-driven facilities for Rapid Small-Scale Column Testing (RSSCT) and thermally rejuvenated carbon — evaluating media and simulating full-scale performance to guide utilities to the most effective, affordable, data-validated treatment.
Rapid Small-Scale Column Tests (RSSCT) simulate the conditions of a full-scale filter bed, allowing performance testing of media to remove contaminants from water. Birchtech specializes in RSSCTs for evaluating activated, virgin, spent, and reactivated carbon as well as ion exchange resin.


Birchtech’s rjGAC™ services modify activated carbon and rigorously compare its performance against other carbon — covering activation, reactivation, and regeneration. Insights from our detailed analysis drive expert recommendations for the most cost-effective, efficient water treatment.
Our Design Centers focus on research and innovation to address the most pressing challenges in water treatment.
Targeting PFAS and other harmful substances with advanced removal techniques to meet evolving regulatory standards.
Designing technologies that reduce environmental footprints while improving efficiency and affordability for utilities.
Streamlining research processes to deliver effective products faster, ensuring rapid deployment for critical needs.
Developing next-generation activated carbon and alternative media products for diverse water treatment applications.
These advanced facilities provide utilities and industries with comprehensive testing, analysis, and expert guidance for complex water treatment challenges — consultative analysis that meets purification requirements with a sustainable, highly effective, and affordable approach.
From rapid media evaluation in North Dakota to carbon rejuvenation and enhancement in Pennsylvania, each center serves a distinct function in Birchtech’s integrated approach to water treatment.
