Simultaneous degradation of persistent organic pollutants …

1. Introduction. Industrial wastewater effluent containing recalcitrant (non-biodegradable) organic compounds such as from the pulp and paper mill, for instance, can accumulate and agglomerate easily once discharged into aquatic receiving environments [1].The existence and toxicity of these persistent organic pollutants (POPs) (e.g., …

Refractory organic pollutants and toxicity in pulp and paper mill …

This review describes medium and high molecular weight organic material found in wastewaters from pulp and paper industry. The aim is to review the versatile pollutants and the analysis methods for their determination. Among other pollutants, biocides, extractives, and lignin-derived compounds are major contributors to harmful …

Treatment and Recycling of Wastewater from Sugar Mill

Activated sludge process is used to treat sugar mill wastewater using air and a biological floc composed of microbes. In general, the process occurs in two steps, viz; adsorption and biological oxidation. The technique could effectively remediate the organic pollutants of the wastewater. 7.4.2.2.2 Trickling Filter Method

A review on current techniques used in India for rice mill wastewater

The rice mill wastewater has a high concentration and wide range of organic matter, total dissolved solids, phenol and nutrients (Table 2).The huge variation in pH and organic matter concentrations depend upon the paddy characteristics, milling process and quality and quantity of water used for parboiling (Kumar et al. 2016a).The effluent …

Characterization of Autochthonous Bacteria Capable for Degradation …

Evaluation of remediation of organic pollutants The characterisation and identification of residual organic pollutants was done by GC-MS analysis from pulp paper industry effluent discharged after secondary treatment. The evaluation of degraded organic pollutants before and after biostimulation process revealed the change in peak height and ...

Pulp and paper industry–based pollutants, their health …

The particle pollutants of pulp and paper mill are mostly present in the complex form of inorganic metallic and nonmetallic effluents. The chief metals released from the paper mill are manganese (Mn), chromium (Cr), Iron (Fe), cadmium (Ca), and nonmetallic elements are primarily sodium, calcium, magnesium, sulfate, and chlorine …

Defect engineered oxides for enhanced mechanochemical destruction …

Such process, quite unexpectedly, occurs also with nonreducible metal oxides. This phenomenon is of primary importance when organic and inorganic materials are co-milled together, because it may affect the integrity of the organic components. Actually, this effect is desired in MC destruction of organic pollutants.

Degradation and Mineralization of Organic Pollutants …

In this work, UV/H2O2 treatment of actual pulp and paper mill wastewater (PPMW) was investigated. To determine optimal conditions, the effects of some experimental parameters (initial pH, initial H2O2 concentration, temperature, and organics load) on the UV/H2O2 process efficiency in terms of absorbance at 330 and 281 nm …
