Laccase-based Biocatalytic Systems for Recalcitrant Micro-Pollutants Degradation and Energy Generation
… contamination of freshwater system with micro-pollutants emerges as a critical environmental problem, which has driven the search for novel mitigation approaches. The use of enzymes such as laccase as biocatalyst has been recognised as a promising approach for micro-pollutants removal. …

Removal of Organic Micro-Pollutants from Water Using Sewage Sludge Based Composite Adsorbents
… adsorbents to remove various types of organic pollutants, emerging organic contaminants in particular, from wastewater and drinking water sources.</p> <p>It is hypothesized that a hydrophobic carbon phase in the composite material would promote the physical adsorption of non-polar organic …

Modelling, Simulation, and Optimisation of Reverse Osmosis Process with Application in Wastewater Treatment and Food Processing
… industrial applications contain a variety of micro-pollutants and highly-toxic compounds, which are released into a variety of water resources. Such pollutants not only disrupt the biological ecosystem, but they also pose a real threat to the water supply for human consumption and to the …

Chemical speciation and spatial distribution of heavy metals and their adsorption onto sediments of the Berg River, Western Cape, South Africa
… behaviour of the estuary sediment with micro-pollutants has a significant influence on the environmental quality of estuary waters. For this reason, the absorption of Pb, Cr, Cu, Ni, and Zn onto sediment was study. It was found that the sediments of the Berg River estuary have a low …

Investigation into an adsorption and electrochemical regeneration process for the treatment of two trace level pesticides
The presence of organic micro-pollutants in aquatic systems and drinking water is of concern in most highly populated regions of the planet. Extensive surveys of major river systems in Europe and the United States have measured a wide array of organic contaminants including industrial chemicals, …

Auswirkungen optimierter Straßenabläufe auf Feststoffeinträge in Kanalisationen
… looking at water pollution caused by organic micro elements as many of these micro pollutants preferably accumulate on solid particles and thus enter bodies of water via discharges from sewer systens. In the face of the importance of mineral solids, special efforts to prevent their entry into …

The Effect of Natural Organic Matter on UV/H<sub>2</sub>O<sub>2</sub> Treatment and the Effect of UV/H<sub>2</sub>O<sub>2</sub> Treatment on Natural Organic Matter
… produces hydroxyl radicals that degrade organic micro-pollutants. However, radicals react non-selectively with natural organic matter (NOM). This research effort quantified the effect of NOM variation on the efficiency of UV/H<sub>2</sub>O<sub>2</sub> contaminant destruction, explored the …

Biochemistry of micro-polutants in sediments of Mtoni estuary, Tanzania
… the variability in the distribution of potential micro-pollutants in the mangrove sediments of Tanzanian coast. Sandy particles dominated the mangrove sediments, with less than 6% of organic matter (OM) in the estuary and less than 9% in the tributaries. Similarities in the levels of total organic …

Membranbioreaktoren zur industriellen Abwasserreinigung
… the molecular weight cut off of the applied micro- or ultrafiltration membranes is of minor importance. Desired filtration performance and especially variances from municipal applications are primarily determined by the fouling factors "colloidal fouling" and "scaling". Suitable methods have …
