PeCOD® COD Analyzer Featured in International Environmental Technology Journal
The latest edition of International Environmental Technology Journal showcases the peCOD technology and how it is improving mill performance, wastewater treatment, and health and safety. Results from a transnational research project confirmed the peCOD method as an accurate and reliable tool for monitoring chemical oxygen demand (COD) in the pulp and paper matrix. With the findings from the project and from other research partners, the PeCOD® COD Analyzer has been implemented into pulp and paper mills for process optimization, process savings, improved health and safety for employees and the environment, and greater success meeting discharge compliance regulations.
Improved Mill Performance, Wastewater Treatment, and Health and Safety with Novel COD Monitoring Technology
PeCOD was selected to help evaluate the effectiveness of the different COD-treatment technologies at various stages in the pulp and paper process. A comparative study was conducted to compare peCOD and CODcr sample results from several effluents at different pulps mills. The peCOD method demonstrated a strong correlation to the CODcr method for all effluent sample types and indicated excellent reproducibility for replicate results. The outcomes from the project have resulted in global adoption of peCOD in pulp and paper mills for treatment monitoring and process optimization. Pulp and paper mills benefitting from the peCOD method have experienced process savings, improved health and safety for employees and the environment, and greater success meeting discharge compliance regulations.
Pulp and paper mills produce a large volume of wastewater and residual sludge, which is a growing concern as environmental regulations become stricter. Experts are looking for solutions to reduce their fresh-water intake and ultimately achieve close to zero liquid discharge. Other challenges facing pulp and paper operations are: high organic concentrations in production and wastewater effluent, operation costs, performance, and impacts to the environment. The EUREKA project was focused on developing novel technologies to treat recalcitrant COD. Its other important focus was to find a faster, more robust COD method to closely monitor effluent levels, to ensure efficient production, sufficient wastewater treatment, and discharge compliance. This article will highlight the development of the peCOD method for COD monitoring and its benefits to the pulp and paper industry.
