  • 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 ...

  • Inhibition effect of phosphorus-based chemicals on corrosion of carbon steel in secondary-treated municipal wastewater

    Secondary-treated municipal wastewater (MWW) could supply a viable alternative water resource for cooling water systems. Inorganic salts in the concentrated cooling water pose a great challenge to corrosion control chemicals. In this study, the inhibition effect of 1-hydroxy ethylidene-1,1-diphosphonic acid (HEDP), trimethylene phosphonic acid (ATMP) and 2-phosphonobutane-1,2,4-tricarboxylic ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Wastewater Level Measurement Techniques

    Level monitoring and control is a fundamental requirement in any wastewater treatment process. You will find level instrumentation installed at even the simplest treatment plants for pump control, chemical storage tanks and process level controls or alarms. Operators have only limited or emergency control over treatment plant influent, so level controls and instrumentation play an important role ...

  • Skimming Oily Wastewater

    As large generators of oily wastewater tighten effluent controls, the U.S. Environmental Protection Agency (EPA) is targeting smaller generators. Some of the firms receiving their attention are smaller manufacturing plants, automotive garages, mobile equipment service shops and truck farms. Many of these firms do not have access to a sanitary sewer system that will accept oily wastewater. Because ...

  • Evaluation of biofilm performance as a protective barrier against biocorrosion using an enzyme electrode

    Sulfide is known to be an important factor in microbiologically influenced corrosion (MIC) of metals and concrete deterioration in wastewater treatment structures and sewer pipelines. A sulfide biosensor was used to determine the effectiveness of Escherichia coli DH5α biofilm as a protective barrier against MIC. The biofilm was shown to be effective in protecting surfaces from sulfide and helping ...

  • Maximize the coating life-cycle in severe wastewater environments

    In 2005, the American Society of Civil Engineers awarded a grade of D- to the nation’s wastewater systems based largely on the deterioration of sewage collection systems. That same year, the Bossier City Public Utilities Department in Louisiana restored a 5,000 square foot lift station using a 100 percent solids epoxy mortar system specifically designed to protect concrete in severe wastewater ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...
