Biotransformation potential of phytosterols under anoxic and anaerobic conditions

The biotransformation potential of three phytosterols (campesterol, stigmasterol and β-sitosterol) under denitrifying, sulfate-reducing and fermentative/methanogenic conditions was assessed. Using a group contribution method, the standard Gibbs free energy of phytosterols was calculated and used to perform theoretical energetic calculations. The oxidation of phytosterols under aerobic, ...

Characterization of dissolved organic matter in the secondary effluent of pulp and paper mill wastewater before and after coagulation treatment

Meeting the regulatory discharge standards for pulp and paper mill wastewater has become ever more difficult because of its recalcitrant and colored dissolved organic matter (DOM). In this study, the variation of DOM from the secondary effluent of pulp and paper mill wastewater before and after coagulation was investigated based on hydrophobicity/hydrophilicity, apparent molecular weight (MW) ...

Determinants of wastewater treatment expenditure of Austrian communities

Wastewater treatment services are bound to rather strict environmental regulations. However, as the broad range of wastewater expenditure of communities shows, there is room for discretionary policies of communities. The current paper explores wastewater treatment expenditure of Austrian communities by employing a cross-section econometric model. To a significant extent, demographic, geographic ...

Pulp & Paper Wastewater Treatment - Innovative Treatment for Efficient Water Management

The paper and pulp industry is among the largest industrial users of water resources operating across the world. Typically, pulp and paper industry operations require on average about 54-70 m3 (18,000 gallons) of water per metric ton (2200 pounds) of processed paper goods. This water usage is staggering, and water is used in almost every single part of the pulp and paper manufacturing process. ...

Understanding a component of industrial papermaking and its pollution load through the application of multivariate analysis

A multivariate analysis technique was used to characterise the interrelationships between the input variables involved in industrial papermaking in order to predict the corresponding wastewater load. The root causes of increasing water pollution load were found to be associated with reprocessing of paper products, pulp stock composition, and inconsistent chemistry for coating operations and paper ...

Nutrient Optimization for Pulp & Paper Wastewater Treatment Plants - An Opportunity for Major Cost Savings

Abstract Pulp & paper wastewater treatment plants (WWTP) often add nitrogen and phosphorus to ensure optimum performance. If there are insufficient nutrients for bacterial metabolism, an increase in effluent total suspended solids (TSS), biological oxygen demand (BOD) and/or chemical oxygen demand (COD) may occur. As well, nutrient deficiency can cause or contribute to acute or chronic ...
