Premium Gas Solutions by Cognituv
Continuous, verifiable microbial control for natural gas.
Premium Gas Solutions by Cognituv (Spicewood, Texas) designs, manufactures and commercializes cleantech hardware and software for mission-critical energy infrastructure. PGS applies our Identify · Apply · Verify™ process to natural gas assets to deliver continuous, verifiable microbial control and predictable gas quality.
RenderingFrom problem to result
Problem
Gas quality issues, aging infrastructure, MIC corrosion, OPEX exposure, downtime and regulatory uncertainty.
Why
Treatment and testing are sporadic, labor-intensive and speculative.
Solution
Continuous, verifiable and automated treatment and testing.
How
The trusted Cognituv process: Identify · Apply · Verify™.
Result
Energy reliability, asset integrity, product security, less O&M, uptime, decarbonization and regulatory confidence.
Source to city
Where microbes hit the gas system.
RNG upgrading and pipeline injection
Bacterial carryover can drive pipeline corrosion (MIC) and interconnect compliance issues.
Underground gas storage
Microbes can sour the gas with H₂S and corrode storage wells and piping.
Transmission pipelines and compressor stations
Sulfate-reducing and acid-producing bacteria (SRB and APB) can cause internal corrosion and leaks.
Pipeline gate and interconnect stations
Microbial contamination at an interconnect can undermine gas quality and safety downstream.
Downstream city distribution
Biofilm pockets in low-velocity mains can add to leak risk.
The challenge
Why it matters.
- Natural gas supplies about a third of the energy the U.S. uses, so reliability and cost stability depend on consistent, compliant gas quality.
- Today’s methods rely on episodic checks and biocide dosing, which leave blind spots between samples.
- Biofilms drive microbially influenced corrosion (MIC): asset degradation, off-spec gas risk, and safety and compliance exposure.

Premium PolisherPatent pending
Inline UV-C treatment engineered for pipeline environments, designed for ≥ 6-log (99.9999%) microbial reduction without chemicals.* An explosion-proof stainless steel vessel with high-output UV-C lamps treats the full stream continuously, delivered skid-mounted and tied into plant PLC and SCADA.
See Premium Polisher* Design target. The Premium Polisher is designed to deliver a UV-C dose of at least 100 mJ/cm² at the end of lamp life. Published doses for comparison: under 20 mJ/cm² for 3-log inactivation of vegetative bacteria, and 78 to 81 mJ/cm² for 4-log inactivation of Bacillus subtilis spores, a standard UV-resistant reference organism. UV-C at 254 nm has inactivated the sulfate-reducing bacterium Desulfovibrio vulgaris. Sources
Performance data based on design basis and published literature under the conditions cited; actual results vary with gas composition, UV transmittance, flow and maintenance.
