underground coal gasification (ucg) is a non-conventional method of extracting gas from coal. the primary advantage of ucg is that it recovers gas from uneconomical or unminable coal, potentially increasing the value of the world’s coal reserves by an estimated 70%; for this reason, ucg has been implemented at sites around the world. however, the gaseous, liquid and solid waste streams which ac...

aims: in biological wastewater treatment processes, a large amount of sludge is produced. stabilization of sludge is essential before disposal because of the risks to human health and environment. therefore, selecting an appropriate process for stabilization this sludge may efficiently decrease risks. the aim of this study was to examine the compound efficiency of the advanced fenton and ozonat...

During 8 sampling campaigns carried out over a period of two years, 72 samples, including influent and effluent wastewater, and sludge samples from three conventional wastewater treatment plants (WWTPs), were analyzed to assess the occurrence and fate of 43 pharmaceutical compounds. The selected pharmaceuticals belong to different therapeutic classes, i.e. non-steroidal anti-inflammatory drugs,...

This work reports some reflections about the European and Italian regulation on sewage sludge. In Europe, the progressive augment of the production of sludge from municipal wastewater treatment plants has recently led to a growing attention about management of this type of solid matrix. European Directives and Italian guidelines stimulated reuse of sewage sludge on agricultural soils or in comp...

A complex activated sludge model implemented in BioWin software has been implemented to assure its predictability and improve the effectiveness of biological wastewater treatment in the fullscale plant in Poland. The influence of temperature and sludge retention time (SRT) on the quality of the effluent was also studied. The calibration was successfully performed according to the Good Modelling...

The following sludge reduction alternatives were tested in wastewater biological reactors: oxic-settling-anaerobic (OSA-process); ultrasonic disintegration (UD); chlorination (CH); 3,3',4',5tetrachlorosalicylanilide (TCS); and folic acid (FA). Compared to the control system, UD reduced 55% of the sludge production, and greater substrate and nutrient removal efficiency was achieved. CH worsened ...

a combination of an acidification reactor and an up-flow staged sludge bed (ussb) reactor wasapplied to treatment of molasses wastewater. the ussb, equipped with three gas solid separators, wasselected because of superior organic removal by means of good retention of granular sludge. the combinedsystem was continuously operated at mesophilic (35°c) conditions for 600 days. the ussb achieved a h...

As input to the steady state design and kinetic simulation models for the activated sludge system, the correct value for the heterotroph anoxic yield is essential to provide reliable estimates for the system denitrification potential. This paper examines activated sludge anoxic yield values in the literature, and presents experimental data quantifying the value. In the literature, in terms of t...

An anaerobic sludge (AS), capable of decolorizing a variety of synthetic dyes, was acclimated and is reported here. The sludge presented a much better dye decolorizing ability than that of different individual strains. A broad spectrum of dyes could be decolorized by the sludge. Continuous decolorization tests showed that the sludge exhibited the ability to decolorize repeated additions of dye....

This article describes a research attempt to integrate the dewatered alum sludge, a residual by-product of drinking water treatment process, into a constructed wetland (CW) system for the purpose of enhancing the wastewater treatment performance, thus developing a so called alum sludge-based constructed wetland system. A multi-dimensional research project including the batch tests of phosphorus...
