“…Shah, Ali et al [21] and Tanaka, Fujimoto et al ( 2008) [22] proposed that a hybrid methodology comprised of coagulation and adsorption was a more cost effective, environ-mentally friendly, and optimized treatment. Earlier, several studies have shown biological nutrient removal possibilities [23][24][25][26][27][28][29][30] studied the removal of nutrients from wastewater by using polyethylene biofilm carriers as well as studies on adsorption of hazardous dyes [31][32][33].…”

“…The BNR process is improved by developing optimized biotechnological and novel strategies in nitrogen bioremediation [10]. Recently, researchers are making great efforts to apply novel strategies to achieve high nitrogen removal efficiency, for example, coupling anammox with partial-denitrification (PD-A) [11], enhancing the anammox process by switching between warm side-stream and cold mainstream wastewater flows [12], coupling partial nitrification with anammox (PN-A) [13], real-time oxidation reduction potential (ORP) decrease rate control in a PN-A system [14], and achieving simultaneously enhanced nitrogen removal efficiency and electricity generation by coupling bio-electrochemical system (BES) with PD-A [15]. Traditional microbial techniques applied in culturing of BNR microbes in the laboratory have contributed immensely to what is known about the biodiversity of BNR microbial communities in natural and engineered systems.…”

Biological Nitrogen Removal Database: A Manually Curated Data Resource

Biological nitrogen removal (BNR) technologies are the most effective approaches for the remediation of environmental nitrogen pollutants from wastewater treatment plants (WWTPs). Presently, research is going on to elucidate the structure and function of BNR microbial communities and optimizing BNR treatment systems to enhance nitrogen removal efficiency. The literature on BNR microbial communities and experimental datasets is not unified across various repositories, while a uniform resource for the collection, annotation, and structuring of these BNR datasets is still unavailable. Herein, we present the Biological Nitrogen Removal Database (BNRdb), an integrated resource containing various manually curated BNR-related data. At present, BNRdb contains 23308 microbial strains, 46 gene families, 24 enzymes, 18 reactions, 301 BNR treatment datasets, 860 BNR-associated next-generation sequencing datasets, and 6 common BNR bioreactor systems. BNRdb provides a user-friendly interface enabling interactive data browsing. To our knowledge, BNRdb is the first BNR data resource that systematically integrates BNR data from archaeal, bacterial, and fungal communities. We believe that BNRdb will contribute to a better understanding of BNR process and nitrogen bioremediation research.

“…Literature reported organic and nutrient removal process to solve the problem of toxicity with biofilms for more economic nitrogen removal [9]. In wastewater treatment, it is stated that biofilm process is present and has degradation possibilities for biogas effluent treatment and is cited in newer publications regarding ORP control and electricity production combined with wastewater treatment [10]. The parameters such as pH, alkalinity, and inorganic carbon content significantly influence the process [11,12].…”

Cascade Membrane System for Separation of Water and Organics from Liquid By-Products of HTC of the Agricultural Digestate—Evaluation of Performance

et al. 2021

New regulations aimed at curbing the problem of eutrophication introduce limitations for traditional ways to use the by-product of anaerobic digestion—the digestate. Hydrothermal carbonisation (HTC) can be a viable way to valorise the digestate in an energy-efficient manner and at the same time maximise the synergy in terms of recovery of water, nutrients, followed by more efficient use of the remaining carbon. Additionally, hydrothermal treatment is a feasible way to recirculate recalcitrant process residues. Recirculation to anaerobic digestion enables recovery of a significant part of chemical energy lost in HTC by organics dissolved in the liquid effluent. Recirculating back to the HTC process can enhance nutrient recovery by making process water more acidic. However, such an effect of synergy can be exploited to its full extent only when viable separation techniques are applied to separate organic by-products of HTC and water. The results presented in this study show that using cascade membrane systems (microfiltration (MF) → ultrafiltration (UF) → nanofiltration (NF)), using polymeric membranes, can facilitate such separation. The best results were obtained by conducting sequential treatment of the liquid by-product of HTC in the following membrane sequence: MF 0.2 µm → UF PES 10 → NF NPO30P, which allowed reaching COD removal efficiency of almost 60%.
