Packing materials used in biofiltration of gaseous pollutants represent a key design parameter, as proper selection might not only determine the adequate performance system but also its cost-effectiveness. This study systematically assessed and compared conventional plastic carrier with that two novel clay-based from SAINT GOBAIN for abatement model odorous stream composed H2S, methylmercaptan ...

The effect of the partition coefficient on simulation operation a biotrickling filter treating mixture sulfur compounds was analyzed to evaluate pertinence using Henry’s law in determining its removal capacity. analysis consisted that bio-oxides hydrogen sulfide (H2S), dimethyl (DMS), methyl mercaptan (MM) and disulfide (DMDS) different types models for coefficient: pure water, adjusted from ex...

BACKGROUND/AIMS Patients with chronic renal failure show the presence of massive oxidative genome damage but the role played by dialysis is still a controversial issue. The aim of our study was to verify the genomic damage in B- and T-lymphocyte subpopulations of uremic patients after a single hemodiafiltration session. METHODS We enrolled 30 patients on maintenance acetate-free biofiltration...

Biological waste gas cleaning is gaining more and more importance for the removal of the volatile organic compounds from air polluted streams. In order to investigate the performance of this technology a biofiltration pilot unit was operated for a continuous period of 14 months. The biofilter was packed with newly developed compost pellets and a mixture of compost and peat. At start-up, the bio...

A survey of 16 US drinking water treatment plants was conducted on the occurrence, formation, and control of emerging disinfection by-products (DBPs). The formation and control trends of certain emerging carbonaceous (haloacetaldehyde) and nitrogenous (haloacetonitrile, halonitromethane, cyanogen halide, nitrosamine) DBPs were different from those of the regulated trihalomethanes (THMs). This w...

Abstract In this paper, the problems which can occur when wastewater is discharged into surface water bodies are considered. Modern methods of treatment presented: mechanical, chemical, biological, physical-and-chemical, and combined methods. Examples green infrastructure technologies with biofiltration function given, easy to use effective in both urban production runoffs, principles landscape...
