“…Taking the volume of the packing material in the column, the porosity of the bed material and the density of the cellular concrete into account, it can be calculated that the increase in the percentage weight 11 of the sulfur component was consistent with the amount of H 2 S calculated from the mass balance. The corrosion of concrete due to the presence of H 2 S is well documented in the literature, especially in sewer systems [38]. However, there are no data suggesting a single-step reaction between H 2 S and concrete [39].…”

“…However, there are no data suggesting a single-step reaction between H 2 S and concrete [39]. There are indications of multi-step reactions leading to the formation of sulfate, gypsum, ettringite and pyrite [38,40,41]. Moreover, the interactions between H 2 S and concrete depend on its composition, which is mainly influenced by the type of binder used.…”

“…The influence of iron was investigated because the addition of iron salts is widely used to control H 2 S emissions in sewer systems [38] and several materials containing iron oxide, like sewage sludge, red mud, bottom ashes or steel slags, have been identified as possible iron sponges for H 2 S removal [42]. An analysis by X-ray diffraction (XRD) was carried out before and after treatment.…”

AbstractThe objective of this study was to investigate the removal of hydrogen sulfide (H 2 S) present in air using cellular concrete waste as the packing material. Air filtration was performed under biotic and abiotic conditions. Experiments were carried out in a laboratory-scale PVC column (internal diameter of 300 mm) filled with a volume of 70 L of cellular concrete (1 m height).The polluted air flow was generated at 4 m 3 h -1 corresponding to an Empty Bed Residence Time (EBRT) of 63 s. In dry conditions without biomass (abiotic conditions), cellular concrete can be an effective medium for the treatment of H 2 S in air. For an H 2 S concentration of 100 ppmv, the removal efficiency was around 70 % (Elimination Capacity (EC) of 5.6 g m -3 h -1 ). This finding can be explained by the physicochemical reactions that can take place between H 2 S and the cellular concrete components (mainly CaO, CaCO 3 and Fe 2 O 3 ).However, interactions between cellular concrete and H 2 S are not yet fully understood. Used as a packing material for H 2 S biofiltration (biotic conditions), cellular concrete waste efficiently 2 treated (Removal Efficiency = 100 %) high concentrations of H 2 S (up to 133 ppmv corresponding to an EC of up to 10.5 g m -3 h -1 ). Physicochemical and biological mechanisms explaining H 2 S removal seem to occur simultaneously in the biofilter. At an EBRT of 63 s, the maximal elimination capacity (EC max ) was 17.8 g m -3 h -1 . A packed bed of cellular concrete also presents a satisfactory mechanical behavior with low pressure drops.

“…Sulfide, which is a common and undesirable water pollutant [26,27], has been selected as an efficient sacrificial electron-donating solute. In addition to the sulfide anion, its conjugated acid hydrogen sulfide is a large scale by-product in petrochemical processing [28,29] (where it is converted to elemental sulfur for disposal), and uses thereof are intensively sought as a desirable strategy for its valorisation as a feedstock [30].…”

Copper-doped titanium dioxide materials with anatase phase (Cu-TiO 2 , atomic Cu contents ranging from 0 to 3% relative to the sum of Cu and Ti), and particle sizes of 12-15 nm, were synthesised by a solvo-thermal method using ethanol as the solvent and small amounts of water to promote the hydrolysis-condensation processes. Diffuse reflectance UV-vis spectroscopy show that the edges of absorption of the titania materials are somewhat shifted to higher wavelengths due to the presence of Cu. X-Ray Photoelectron Spectroscopy (XPS) indicate that Cu(II) is predominant. Photocatalytic CO 2 reduction experiments were performed in aqueous Cu-TiO 2 suspensions under UV-rich light and in the presence of different solutes. Sulfide was found to promote the efficient production of H 2 from water and formic acid from CO 2 . The effect of the Cu content on the photoactivity of Cu-TiO 2 was also studied, showing that copper plays a role on the photocatalytic reduction of CO 2 . IntroductionCarbon dioxide is an inexpensive and widely available feedstock. Its use for the production of chemicals is doubly beneficial, since in addition to its availability, it would represent a decrease in the carbon footprint for the manufacturing of the particular chemical. Other researchers have reported lower but noticeable methanol yields using similarly prepared photocatalysts and Hg lamp irradiation (10-23 µmol g cat −1 h −1 ) [19,20]. In gas-phase reactions, the formation of methanol was also reported, but in considerably lower yields (2 nmol g cat −1 h −1 ), being methane the major product formed by Cu/TiO 2 photocatalysis [21]. In contrast, similar materials were found to promote the formation of several hydrocarbons including methane, ethane and ethylene in conjunction with larger amounts of H 2 [22], whereas CO and methane were major products found in a more recent study [23]. A significant degree of discrepancy regarding the identity of the reaction products (in addition to their selectivities and yields) is apparent by considering the aforementioned literature data, although this could be in part due to the different synthetic procedures used for the preparation of the photocatalysts and to the varied irradiation conditions used.Despite the notable progress in this field of research, there is no clear trend which may allow to conclude on the actual mechanistic route and to gain knowledge on the role of copper on the reaction. Thorough kinetic and in situ spectroscopic studies would provide valuable information on the reaction at the surface of the photocatalyst and may guide future design of more active copper-titania materials. An important issue to focus on is the possible back-reactions of the reduction products on the photocatalyst. For example, it was observed that methanol and formaldehyde, initially formed by a photocatalytic process using Cu(0) powder and TiO 2 , were 3 rapidly consumed by in situ formed Cu/TiO 2 [24]. The simultaneous occurrence of CO 2 reduction and decomposition of the products should result in stat...

“…Microbial activity in the current sewer systems is not desirable since it leads to the formation of the greenhouse gas methane (Foley et al, 2009) and to hydrogen sulphide formation and the subsequent corrosion of sewers (Zhang et al, 2008). Furthermore, in the ZeroWasteWater concept, hydrolysis of particulate COD and consumption of dissolved COD should be minimal to obtain a maximum COD load to the treatment plant and a performant solid/liquid separation at the income of the plant.…”

Actual sewage treatment relies on conventional activated sludge (CAS), which reaches sufficiently low carbon, nitrogen and phosphorus effluent levels, but is not cost-effective, hardly achieves recovery, requires electricity equivalent to a fossil fuel consumption of 85 kWh per inhabitant equivalent (IE) per year and has an operational CO 2 footprint of 80 kg CO 2 IE −1 year −1 . Projected water and phosphorus shortages and the need to lower greenhouse gas emissions force us to rethink wastewater treatment for sustainable cities of the future. ZeroWasteWater offers an approach to short-cycle water, energy and valuable materials while adequately abating pathogens, heavy metals and trace organics. A less diluted waste stream will be obtained from sewerage improvements, a more rational use of potable water and the addition of ground kitchen waste, complemented by an advanced physicochemical or/and biological concentration step at the entry of the sewage treatment plant. Anaerobic digestion will recover electricity from the concentrated stream and further treatment will render a value of 6.2 EUR IE −1 year −1 under the form of the nutrients nitrogen and phosphorus, and the carbon-sequestrating biochar. In the water stream, residual nitrogen will be removed through partial nitritation and anammox, followed by heat recovery and add-on membrane technologies yielding potable water (> 65 m 3 IE −1 year −1 ). Overall, compared to a CAS system without sludge digestion, the recovery of energy and nutrient in ZeroWasteWater avoids a fossil fuel use of 439 kWh IE −1 year −1 and an operational emission of 88 kg CO 2 IE −1 year −1. Interestingly, such approach is expected to be economically viable. The key challenges remain to incorporate water chain management in holistic urban planning and to render a cradle to cradle approach which society will find acceptable.
