Biological and Membrane Treatment Applications for the Reduction of Specific Conductivity and Total Dissolved Solids in Coal Mine Waters
… in coal mine waters. In literature examining the treatment of mine waters, SC and TDS analysis is typically not reported. The technologies examined in this study were nanofiltration membrane technology and biological sulfate reducing bioreactors. In the nanofiltration study, three different …

Characterization and treatment of organic matter, UV quenching substances, and organic nitrogen in landfill leachates
… on-site before disposal to municipal wastewater treatment plants, although variations in leachate composition and organic loading continue to have negative impacts on downstream treatment processes. Leachate samples were collected from four landfills both before and after on-site treatment to …

Effect of wastewater colloids on membrane removal of microconstituent antibiotic resistance genes
… there is growing interest in advancing water treatment processes capable of limiting ARG dissemination. This study examined the potential for membrane treatment of microconstituent ARGs, and the effect of wastewater colloids on their removal. Native and spiked extracellular vanA (vancomycin …

Characterization and treatment of UV quenching substances and organic nitrogen in landfill leachates and thermal hydrolysis/anaerobic digestion centrate
… centrate can quench UV light at publicly owned treatment works (POTWs). Increased eutrophication, has led to tightening of nutrient discharge limits in some regions of the country. Biologically recalcitrant organic nitrogen, adds to effluent nitrogen making it difficult to meet these …

Improved filtration membranes through self-organizing amphiphilic comb copolymers
The operating cost of a membrane filtration system is generally determined by two major factors: the permeability of the membrane to water, and the lifetime of the membrane. Both of these are strongly affected by the chemical structure and surface properties of the membrane. Hence, the development …

Emergence and fate of iodinated organic compounds and disinfection by-products during biological treatment of oil and gas produced water
… in several water-intensive sectors. Several treatment technologies to improve water quality for potential surface discharge, live-stock watering, dust suppression, and on-site water reuse can be implemented. Biological active filters (BAFs) are one treatment technology that can be effectively …

Effects of transmembrane hydraulic pressure on the performance of forward osmosis membranes, The
Forward osmosis (FO) is an emerging membrane separation process that continues to be tested and implemented in various industrial water and wastewater treatment applications. Breakthroughs in research and manufacturing have produced better performing membranes with improved structural integrity and …

Treatment of Landfill leachates using anion exchange resins
… leachates are often discharged to wastewater treatment plants (WWTPs) but their highly varied composition makes their treatment in WWTPs difficult. Landfill leachates contain bio-refractory organic matter which easily passes the biological treatment processes at WWTPs and increases the organic …
