“…Most existing BSs are designed for the removal of a single pollutant. For example, Nisola et al [87] developed a single BS for ammonia removal; Potivichayanon et al [88] investigated a fixed-film BS for hydrogen sulfide removal. Contrarily, various design modifications have been reported to handling pollutant mixtures, such as sorptive-slurry BS, anoxic BS, two-liquid phase BS, airlift BS, spray column or two-stage BS [89].…”

The ever increasing public complaints arising from wastewater treatment plants (WWTPs) grow since sewerage treatment has been associated with nauseous odorous on account of the anaerobic decomposition process and emission. Various physical/ chemical and/or biological methods were used for abating odours worldwide. Thus, an updated comprehensive review for the WWTP odor abatement technologies is urgently required. This study reviews the new achievements of odor abatement technologies (adsorption, chemical scrubbing, biofiltration, biotrickling, bioscrubbing, activated sludge diffusion) in WWTPs and then identifies a new aspect for the future studies. Overall, hybrid technologies (physical/chemical + biotechnologies) attract increasing attention since their highly reliable removal efficiency for various odorants, however, the high costs for investment and O&M (operation & maintenance) of the adsorption part and the complexity and variability of odorants are still the major challenging for wide engineering application and technological innovation. Thus, developing the cost-effective, environmentally friendly odor control technologies, like using the alum sludge (waterworks residue) based adsorbents/media, in terms of using "waste" for waste treatment, could be a highly promising prospect.

“…Technically, there are a large number of different gas scrubbers with different designs, which have advan-tages and disadvantages and are better or worse suited for certain applications. For the application at hand, spray scrubbers and bubble column reactors are particularly suitable, which have also already proven themselves for the separation of ammonia from the exhaust air in animal fattening plants and biogas plants [8,9].…”

During the calcination of magnesium ammonium phosphate hexahydrate (struvite) in the process of recycling to obtain phosphoric acid, ammonia is released in addition to water and carbon dioxide. With a gas scrubber, e.g., in the form of a bubble column reactor, ammonia can be recovered as a usable valuable material. With water as an inexpensive and effective absorbent, almost complete absorption (92 %) of the ammonia from the exhaust air can be achieved.

“…Thus, to improve AOB microbial density, immobilization techniques using suitable support matrices such as polyurethane have been employed [6,8]. Alternatively, hollow fiber (HF) membranes are excellent support matrices due to their high specific surface area that provides ample space for microbial growth [9].…”

A B S T R A C TAmmonia removal via nitrite was performed in membrane-aerated biofilm reactors (MABR). Two types of hollow fiber (HF) modules, uncoated microporous polyvinylidene fluoride (PVDF) and composite polyether-block-polyamide copolymer (PEBA) coated PVDF, were used as supports for the growth of ammonia oxidizing microorganism biofilm system. For the composite HF, a suitable coating material was selected between hydrophilic and hydrophobic types of PEBA. Results reveal that hydrophobic PEBA 2533 was more suitable for bacterial adhesion. The formation of coating layer was successfully confirmed through field emission scanning electron microscope. Other surface characterizations were performed through atomic force microscopy and contact angle measurements. Partial nitrification experiments at varied feed concentrations and hydraulic retention times reveal that MABR with uncoated PVDF HF exhibited slightly higher ammonia removal than the MABR with composite HF. In terms of nitrified products, MABR with composite HF produced > 90% of the removed ammonia in nitrite form. On the other hand, around 50% of nitrite was converted to nitrate in the MABR with uncoated PVDF. Thus, between the two membranes tested, PEBA 2533 coated PVDF is the more suitable HF for ammonia removal via nitrite formation in the MABR system.
