Lab-validated Rapid Small-Scale Column Testing that screens candidate media against your own source water, faster and more affordably than full-scale column tests.
Our experts offer a deep understanding of activated carbon, sorbent technologies, and regulatory compliance requirements to support optimized treatment solutions for the removal of contaminants, including PFAS. Birchtech provides expert analytical services and RSSCT evaluations for a variety of treatment media, including virgin and reactivated granular activated carbons (GACs), ion exchange resins, and multiple water matrices.
PFAS analysis of RSSCT samples is performed in-house on high-sensitivity LC-MS/MS instrumentation under PFAS-controlled laboratory practices, using a direct injection approach based on EPA Method 8327.
RSSCT data functions as performance data for media screening rather than compliance reporting, so it is not bound to certified drinking water methods.
Download brochureDr. Nicholas Lentz explains Birchtech’s RSSCT, faster, more accurate, more affordable PFAS media analysis.
Lab-validated performance data generated on your actual source water.
Compare media without full-scale column-test investment.
Column testing in as fast as one to three days, with automated around-the-clock sampling. Typical turnaround from sample receipt to report is two to four weeks.
Clear formats for utilities, service providers, and consultants.

Provide samples of your water source and candidate sorbent media.

We conduct rapid small-scale column tests simulating full-scale conditions.

Sorbent effectiveness assessed against target contaminants.

Comprehensive analysis delivered to support your decision-making.
A lab-driven approach to media evaluation that reduces cost and accelerates compliance timelines.
Compare media efficiency for informed decisions. Evaluate activated carbon, ion exchange resins, and alternatives.
The highest-performing media is not always the right choice. Compare candidates on performance and cost together.
Accurately detect removal performance for PFAS compounds and regulated contaminants.
Generate site-specific performance data to support media selection and inform treatment and operational decisions.
In-house expert analysis using advanced lab equipment and research-backed methods.
Evaluate how empty bed contact time affects performance, including the tradeoff between longer contact time and a larger system.
Birchtech recommends the media that best matches your water. The Design Center screens candidate media by RSSCT, and our wider water treatment practice works across adjacent media, because real water rarely fits one solution.

Virgin, activated, and reactivated GAC for PFAS removal.

Blended strategies tailored to source water chemistry, applied at system design stage.

Selective resins evaluated for PFAS and emerging contaminants.

Specialty carbons for targeted removal, supplied through our water treatment practice.
Beyond RSSCT performance testing, the Design Center laboratory is equipped to perform PFAS analyses by EPA Methods 533, 537.1 and 1633.
Pilot testing, system design, or a full-scale SEA® deployment: our Design Center responds within two business days.
