MANTECH PeCOD - Model Benchtop L50 -Chemical Oxygen Demand (COD) Analyzer

Fast, Green, and Accurate Chemical Oxygen Demand Analysis

MANTECH’s PeCOD® analyzer is a fast, green, and safe method for analyzing chemical oxygen demand (COD) and/or biochemical oxygen demand (BOD) without the use of harmful chemicals such as dichromate and mercury. Utilizing a patented nanotechnology-based approach, the PeCOD® analyzer delivers accurate, timely and actionable results in 10-minutes or less.

PeCOD is the fastest available method for quantifying chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in 10-minutes or less. Operators can obtain fast, accurate results for optimization and make informed, timely decision on the spot instead of having to wait the standard 5-day or 7-day wait. 

PeCOD nanotechnology provides a higher oxidizing power and none of the risks associated with harmful chemicals such as dichromate and mercury. It’s safe and simple to use for any laboratory or operations staff member at any point in the process.

The core of the technology is the PeCOD sensor, which consists of a UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst coupled to an external circuit. When a sample is introduced into the microcell containing the PeCOD sensor, the TiO2 is irradiated by UV light, and a potential bias is applied. The UV light creates a photohole in the TiO2 sensor with a very high oxidizing power and organics in the cell are oxidized. PeCOD is extremely accurate across a broad range of organics. The powerful oxidizing potential of UV-illuminated TiO2 ensures that virtually all species will be fully oxidized giving a true measure of COD.

The PeCOD® COD Analyzer technology is a proven performer in a variety of municipal and industrial wastewater applications. Recent studies have shown a strong correlation between the 10 minute PeCOD method for testing chemical oxygen demand (COD) and standard dichromate COD (COD_CR) and five-day BOD (BOD₅) methods. In most cases, PeCOD can be used as a BOD screening tool, providing accurate BOD estimates in just minutes versus several days.

The PeCOD® COD Analyzer will be the technology of choice as new regulations take effect in Europe in September 2017 that will eliminate the use of dichromate in COD testing. PeCOD conforms to Method E3515, released in 2014 by the Ontario Ministry of Environment and Climate Change (MOECC) to replace the dichromate method for COD testing. PeCOD is also included as an approved alternate COD method in the Protocol for the Sampling and Analysis of Industrial/Municipal Wastewater which was updated in 2016 by the MISA (Municipal Industrial Strategy for Abatement) program.

The PeCOD® COD Analyzer is available in a variety of configurations- the benchtop, online and automated and each configuration uses the same innovative technology and method.

The PeCOD® Analyzer is optimal for certain industries including: 

• Municipal and Industrial Wastewater Treatment Plants 
• Pulp and Paper Mills 
• Food and Beverage Production 
• Biogas Plants 
• Breweries 
• Wineries

MANTECH is excited to announce that the release of the PeCOD L50 Model! See here for more details.

The L50 is a direct replacement for the L100 shown in previous videos and pictures.  The L50 offers a simpler, industrial and robust design, with improved pricing over the L100.  Contact us for more information.

The PeCOD®  COD Analyzer is available in laboratory, portable and online configurations that are highly customizable. The PeCOD system can be configured to accommodate laboratory operations, automated sampling, or continuous process monitoring.
