The role of nitrite and free nitrous acid (FNA) in wastewater treatment plants
TLDR
A single inhibition mechanism is not sufficient to explain the negative impacts of FNA on microbial metabolisms and that multiple inhibitory effects can be generated from FNA, and further research is necessary before the FNA inhibition mechanisms can be more effectively used to optimize WWTP bioprocesses.About:

Journal ArticleDOI
The inhibition of the Anammox process: A review
TL;DR: In this paper, a detailed review of previous researches on the inhibition of Anammox processes is presented, where the effect of inhibitory substances, such as substrates (ammonia and nitrite), organic matter (nontoxic organic matter and toxic organic matter), salts, heavy metals, phosphate and sulfide, are commonly present in the practical applications.
Journal ArticleDOI
The effect of nitrite inhibition on the anammox process.
TL;DR: The ANAMMOX performance recovered under sulfide-S level of 8 mg L(-1) with a steady NRR increasing speed, linear relationship between the NRR and operation time, and the synchronic reduce in the specific ANAM MOX activity and the biomass extended the apparent doubling time of the nitrogen removal capacity and decreased biomass growth rate.
Journal ArticleDOI
Detection of nitrifiers and evaluation of partial nitrification for wastewater treatment: A review.
TL;DR: Control strategies for obtaining partial nitrification are mainly focused on the pH, temperature, dissolved oxygen concentration, real-time aeration control, sludge retention time, substrate concentration, alternating anoxic and aerobic operation, inhibitor and ultrasonic treatment.
Journal ArticleDOI
The roles of free ammonia (FA) in biological wastewater treatment processes: A review.
TL;DR: FA can be leveraged to substantially enhance the biodegradability of secondary sludge, which would further improve biological nutrient removal and enhance renewable energy production.
Journal ArticleDOI
Side-stream sludge treatment using free nitrous acid selectively eliminates nitrite oxidizing bacteria and achieves the nitrite pathway.
TL;DR: The FNA-based strategy for establishing the nitrite pathway substantially improved total nitrogen removal, and did not increase N2O emission or deteriorate sludge settleability.

Inhibition of anaerobic digestion process: A review
TL;DR: This review provides a detailed summary of the research conducted on the inhibition of anaerobic processes and indicates that co-digestion with other waste, adaptation of microorganisms to inhibitory substances, and incorporation of methods to remove or counteract toxicants before an aerobic digestion can significantly improve the waste treatment efficiency.

Biochemistry of nitric oxide and its redox-activated forms
TL;DR: The integration of this chemistry with current perspectives of NO biology illuminates many aspects of NO biochemistry, including the enzymatic mechanism of synthesis, the mode of transport and targeting in biological systems, the means by which its toxicity is mitigated, and the function-regulating interaction with target proteins.

Inhibition of nitrification by ammonia and nitrous acid
TL;DR: The importance of NITRIFICATION has been recognized for more than a hundred years and engineers and scientists continue to investigate the process to obtain a better understanding of the fundamentals and to use the process for the benefit of man.
Journal Article
Inhibition of nitrification by ammonia and nitrous acid.
TL;DR: Control nitrification may occur during waste treatment, and engineers have begun to incorporate the process as part of nitri fication-denitrification systems for nitrogen control preceding discharge of the treated wastes.
