“…This provides a concentrated stream of NH 4 + [18,20]. Other regeneration techniques such as acid regeneration [20], heating regeneration (particularly useful for exothermic adsorption process) [23•], and biological regeneration [27] can also be used, depending on the recovery process employed subsequently [20]. The regeneration step results in concentrated stream of NH 4 Cl in chemical regeneration [19,25] or NaNO 3 in biological regeneration [27,28].…”

“…It is also a significant contaminant in domestic grey water and urine [16]. Because it is a cation, ion exchange and adsorption-based processes are highly relevant because of their unique properties such as high selectivity for NH 4 + , high removal, fast uptake kinetics and regeneration [17][18][19][20], less space requirements and simplicity of application and operation [21], being environmental friendly [22] as it uses naturally occurring and easy-to-modify ion-exchanger/adsorbent such as zeolite [23•], and releases non-toxic exchangeable cations (Na + , K + , Ca 2+ , and Mg 2+ ). The most popular ion exchanger/adsorbent for nitrogen recovery is zeolite.…”

Nitrogen and Phosphorus Recovery from Wastewater

Use of nitrogen-and phosphorus-based synthetic fertilizers shows an increasing trend, but this has led to largescale influx of reactive nitrogen in the environment, with serious implications on human health and the environment. On the other hand, phosphorus, a non-renewable resource, faces a serious risk of depletion. Therefore, recovery and reuse of nitrogen and phosphorus is highly desirable. For nitrogen recovery, an ion exchange/adsorption-based process provides concentrated streams of reactive nitrogen. Bioelectrochemical systems efficiently and effectively recover nitrogen as NH 3 (g) or (NH 4 ) 2 SO 4 . Air stripping of ammonia from anaerobic digestate has been reported to recover 70-92 % of nitrogen. Membrane separation provides recovery in the order of 99-100 % with no secondary pollutant in the permeate.With regard to phosphorus (P) removal, physical filtration and membrane processes have the potential to reduce suspended P to trace amounts but provide minimal dissolved P removal. Chemical precipitation can remove 80-99 % P in wastewater streams and recover it in the form of fertilizer (struvite). Acid hydrolysis can convert recovered P into usable phosphoric acid and phosphate fertilizers. Physical-chemical adsorption and ion exchange media can reduce P to trace or non-detect concentrations, with minimal waste production and high reusability. Biological assimilation through constructed wetlands removes both N (83-87 %) and P (70-85 %) from wastewaters, with recovery in the form of fish/animal feeds and biofuel. The paper discusses methods and important results on recovery of nitrogen and phosphorus from wastewater.

“…Physical nitrogen removal processes -Ion exchange, sorption: Ion exchange, by strong acid cation and weak basic anion resins, is a mature technology developed decades ago, but its high cost may prohibit economic implementation (Koon and Kaufman 1975;Leakovic et al 2000;Jorgensen et al 2003;Thornton et al 2007;Malovanyy et al 2013). However, cheaper absorbents (e.g.…”

The anaerobic fluidized bed membrane bioreactor (AFMBR) is a new energy-neutral methanogenic biological treatment system that combines an anaerobic fluidized bed reactor (AFBR) and internal membranes. It is unique in that the fluidized granular particles, while serving as a surface for active biofilm attachment, rub against membrane surfaces, resulting in a reduction in fouling with low energy expenditure. Fluidized particles denser than water permit good mass transfer, and allow for the maintenance of a large biological population, even at the short hydraulic retention time as required for dilute wastewater treatment. Membranes prevent the escape of volatile suspended solids so they can be biodegraded adequately and removed separately for subsequent disposal. The AFMBR can be used alone for wastewater treatment or as the second reactor in a staged treatment system. Laboratory and pilot studies with domestic wastewater with a staged AFBR-AFMBR system, both containing granular activated carbon particles and operated at total HRT near 6 h and temperatures down to 8 o C, have demonstrated high organic removal efficiency, low waste biosolids production (0.05 kg·kg-COD -1 ), microcontaminant removal efficiencies better than conventional aerobic activated sludge treatment, and a very small footprint. Further research on best approaches for dissolved methane capture and nutrient removal and recovery are ongoing.

“…The removal of lead from water and waste water is important in terms of protection of public health and environment. A number of technologies have been used to remove lead from aqueous solution primarily including chemical precipitation , coagulation, and flocculation , chemical oxidation/reduction , ion‐exchange , electrochemical treatment , and adsorption . In contrast, adsorption technique is one of the preferred methods due to its simplicity as well as the availability of wide range of adsorbents.…”

The superabsorbent composite was prepared by aqueous solution polymerization, using manganese dioxide, acrylic acid, acrylic amide, 2-acrylamide-2-methyl-1-propanesulfonic acid as raw materials, N,N 0 -methylene bisacrylamide as cross-linker, and K 2 S 2 O 8 as initiator. The composite was characterized by Fourier transform infrared spectrophotometer, thermogravimetric analysis and scanning electron microscopy analysis. This article also described the adsorption behavior of the superabsorbent composite with respect to Pb(II) removal from aqueous solution. The kinetic studies for Pb(II) adsorption showed that the pseudo-secondorder adsorption mechanism was predominant. Moreover, adsorption isotherm data were reliably described by the Freundlich model. Regeneration of the adsorbent was attained by 0
