In order to analyse the success of benchmarking undertaken by utilities in the German water sector, an investigation was carried out in the wastewater sector and how benchmarking affected the efficiency of the processes that the utilities carry out. An expanded reprint of a two part paper describe the findings of a survey that aimed at highlighting the aims, effects and success factors of benchmarking.
Improved Wastewater Treatment & Paper Mill Performance With New COD Monitoring Technology
The Nordic Wood Biorefinery Conference was held in Stockholm, Sweden during March 28-30, 2017. An abstract presentation authored by partners from VTT, Kemira, FPInnovations and MANTECH was presented during the conference. The PeCOD® Analyzer has the ability to enable pulp and paper mills to improve effluent treatment process and to optimize chemical programs, leading to proper chemical dosage (not over or under doses) and lower energy requirements for treatment. The strong correlation between the photoelectroch...
Wastewater and groundwater
Nearly 25 percent of the population in the United States—in more than 25 million homes—disposes of wastewater through onsite, or unsewered, systems that return treated effluent to the ground. This is an important public health issue because many of those same homes use wells that rely on groundwater for the drinking water supply. With unsewered systems, homeowners are responsible for treating and maintaining the disposal of wastewater. Most are typically found where centralized wastewater treatment...
Case study - Naini Papers Ltd
Wastewater from bagasse paper processNaini Papers Ltd is part of the Naini Group based in Kashipur, India. The groep`s brand positioning "Ethically Firm, Environmentally Strong" resonates within the business culture of the organization.It is therefore that Naini Papers Ltd chose for HydroThane to upgrade their existing aerobic wastewater treatment plant with an anaerobic ECSB pre-treatment. The anaerobic process not only significantly reduces Naini Papers Ltd environmental footprint, but it also has a positive...
PeCOD® Pulp and Paper Applications - Case Study
The pulp and paper industry utilizes wood as raw material to produce pulp, paper, card board, and other cellulose based products. Pulp and paper mills produce large volumes of wastewater and residual sludge which presents a number of challenges with regards to treatment and discharge. Contaminants in pulp and paper waste streams often include effluent solids, sediments, absorbable organic halides (AOX), chlorinated organic compounds, chemical oxygen demand (COD), and biochemical oxygen demand (BOD). In many...
Case study - Corrosion protection in a pulp and paper industry
It is widely accepted that corrosion has an important economic impact at an industrial scale. As an example, results of a study carried out in the US showed that the total annual estimated direct cost of corrosion in the country was $276 billion, which was approximately 3.1% of the nation’s Gross Domestic Product (GDP). Thus, within the last few decades, an important effort has been made to solve this issue and corrosion management has improved significantly in terms of better solutions, including enhancement...
