Municipal sewage sludge is a solid, semisolid, or liquid muddy looking residue that results after plain old sewage (human and other waste from households and industries) is treated at a waste water treatment plant. Recent restrictions on the use of sewage sludge, however, have resulted in increased disposal problems. Sludge contains a variety of organic and inorganic compounds in the waste wate...

Water detection in hydrocarbon emulsions represents a serious challenge in petroleum production industry. In this paper, a systematic and an applicable method of water detection in hydrocarbon emulsion is achieved using thermoacoustic effect. The study focused on sensing the presence of water in kerosene using the established correlation between the content of hydrocarbon emulsion and the chara...

We report the use of a simple yet highly effective magnetite-waste tea composite to remove lead(II) (Pb(2+)) ions from water. Magnetite-waste tea composites were dispersed in four different types of water-deionized (DI), artificial rainwater, artificial groundwater and artificial freshwater-that mimic actual environmental conditions. The water samples had varying initial concentrations (0.16-5....

sugar beet roots and attached soil are usually transferred to sugar factories for processing ,then the roots are washed by pressurized water. muddy water as waste flows in canal and is used to irrigate fields. the possibility of occurrence and fluctuations of the pathogenic organisms in waste were studied in 2005. the samples were collected from waste water once a week. isolation of pathogens w...

This study was undertaken to evaluate a novel aerobic wastewater treatment model for the remediation of refinery effluents and to assess the removal efficiency of Bulkholderia cepacia strain AJI and Corynebacterium kutscheri strain AJ2 to clean oil waste from petrochemical company. Wastewater quality parameters including pH, BOD5, COD, TDS, OIL & GREASE, PHENOL concentration, TPH and THC were m...

A simple and efficient method using reduced amounts of solvents for the determination polycyclic aromatic sulfur heterocycles (PASHs) in aqueous matrices from a lagoon leachate solid waste petrochemical industry is proposed. The target analytes were previously concentrated disposable pipette extraction (DPX) technique applying gas chromatography-mass spectrometry (GC-MS) analysis. In this innov...

A new absorption vapor compression distillation was proposed in present research. An open absorption heat transformer has a coupled thermally evaporator and absorber. Distillation of waste water with high content of SiO 2 from heavy oil production. The waste heat of 70 C can be elevated up to 125 C and generate steam of 120 C. The waste heat is able to drive four-effect distillation to produce ...

This study analyses the potential of a new eco-friendly bioproduct to construction sustainability and its contribution for improving fresh hardened properties cement mortar. The was obtained from biomass grown using crude glycerol (biodiesel production waste). With similar functionality than petrochemical-based additions, these bioproducts encourage decrease on use fossil-based raw materials wi...
