“…Some of these effluents may benefit from the removal of excess salt and may have some form of waste heat to run the MD process. Some studies have been conducted to evaluate effluent discharges by different industries [333][334][335][336]. A recent study conducted by Dow et al [337] demonstrated that a plastic manufacturer possessed an accessible source of waste heat and a cooling tower blowdown stream that would benefit from a MD desalination treatment.…”

Membrane distillation is a process that utilizes differences in vapor pressure to permeate water through a macro-porous membrane and reject other non-volatile constituents present in the influent water. This review considers the fundamental heat and mass transfer processes in membrane distillation, recent advances in membrane technology, module configurations, and the applications and economics of membrane distillation, and identifies areas that may lead to technological improvements in membrane distillation as well as the application characteristics required for commercial deployment.

“…The composition of generated waste is extremely variable as a consequence of seasonal circumstances, lifestyle, demographic, geographic, and legislation impacts [3][4][5][6][7][8][9][10][11]. This variability makes defining and measuring the composition of waste more difficult and, at the same time, more essential.…”

Summary. Liquid products produced from two different types of waste pyrolysismunicipal wastes and spent tyre wastes are investigated using gas chromatographymass spectrometry. This method has been applied for detailed identification of composition of the samples. The components were characterized in terms of their Kováts retention indices on a PONA capillary column. The obtained analytical data were successfully used for the characterization of the samples. More than three hundred compounds were detected. The liquid products were complex mixtures, composed mainly of C 4 -C 12 compounds. The examination of the selected m/z values very clearly indicates the existence of the different groups of compounds. With a lot of olefins content (31.9%), followed by aromatics (20.0%), paraffins (17.3%), and naphthenes (7.5%), it is described as the liquid product from pyrolysis of municipal solid wastes. The aromatic compounds in liquid product from pyrolysis of spent tyre wastes have the highest concentration (33.5%), and they are followed by naphthenes (28.6%), olefins (19.2%), and paraffins compounds (7.0%). The present study has shown that the pyrolysis of municipal waste and spent tyres can be used as a means for reduction of environmental pollution and production of liquid product which could be used as a fuel source.

“…4,7,8 Their toxicity and malodorous properties deteriorate finished products, 4,5 and must be treated for environmental protection. 6,9,10 Once most NaOH has reacted with sulfur compounds, the solution is known as spent sulfidic caustic (SSC). 11 SSC has high pH (usually above 13), dark color, foul odor and is highly toxic.…”

“…Therefore, it is necessary to perform pre-treatment in order to reduce its impact on effluent treatment units. 10,17 The most common methods used to remove sulfur compounds from SSC are chemical oxidation, air stripping, wet air oxidation and precipitation. 13,[18][19][20][21] Wet air oxidation is conducted under high temperature and pressure.…”

Recebido em 19/8/11; aceito em 7/2/12; publicado na web em 15/6/12 This work examines traditional and new routes for removal of H 2 S and other sulfur compounds from spent sufidic caustic (SSC). SH -(hydrogenosulfide) and S 2-(sulfide) ions were quantitatively oxidized at 25 ºC using H 2 O 2 , NaOCl or a spent sulfochromic mixture. SH -/S 2-ions were also removed via reaction with freshly prepared iron or manganese hydroxides, or after passing the SSC through strong basic anion exchange resins (OH -form). The treated caustic solution, as well as iron/manganese hydroxides, removed H 2 S from diesel samples at 25 o C. SSC treatment via strong basic anion-exchange resins produced the treated caustic solution with the highest free alkalinity.
