This study focused on high-rate nitrogen removal by the anaerobic ammonium oxidation (Anammox) process with a sufficient inorganic carbon (IC) source. Experiments were carried out in an up-flow column Anammox reactor fed with synthetic inorganic wastewater for 110 days. The IC source was added into the influent tank in the form of bicarbonate. The results(More)
A combined process of partial nitrification (PN) and anaerobic ammonium oxidation (anammox) was carried out to treat reject water with a high concentration of ammonium and a low level of hardly biodegraded organic carbon. Stable treatment performance was obtained under high nitrogen loading rates of 5.7 kg-N/m3/day and 10.5 kg-N/m3/day for the PN and(More)
In this study, a lab-scale swim-bed partial nitrification reactor was developed to treat ammonium-rich reject water to achieve an appropriate NO(2)(-)-N/NH(4)(+)-N mixture that could serve as a pretreatment for anaerobic ammonium oxidation (anammox). Strictly controlling the DO concentration was adopted as the main operational strategy. In addition, the(More)
The present study aims to provide a realistic understanding of how the anammox bacterial community and nitrogen removal performance are affected by increasing salt concentrations at ambient temperature. A laboratory-scale investigation was conducted for 92 days, during which the reactor was fed with synthetic inorganic wastewater composed mainly of(More)
The purpose of this study is to investigate the nitrogen removal performance of the anaerobic ammonium oxidation (Anammox) process and the microbial community that enables the Anammox system to function well at ambient temperatures. A reactor with a novel spiral structure was used as the gas-solid separator. The reactor was fed with synthetic inorganic(More)
Completely autotrophic nitrogen removal over nitrite (CANON) is a cost-effective nitrogen removal process. Implementation of the CANON process relies on the cooperation of ammonium-oxidizing and Anammox bacteria, as well as the inhibition of nitrite-oxidizing bacteria. Strict limitations on dissolved oxygen (DO) concentration in the reactor, and the(More)
The feasibility of applying a polyethylene (PE) sponge as a biomass carrier in an anaerobic ammonium oxidation (anammox) reactor and its nitrogen removal performance were also investigated. Experiments were carried out in an up-flow column reactor with synthetic inorganic wastewater. Experimental results indicate that reactor containing PE sponge biomass(More)
NEAT1 has been reported to affect cancer progression, which was subsequently confirmed in multiple cancers. Hsa-miRNA-335-5p (miR-335-5p) has recently been identified as an anticancer agent in various organs. However, the relationship between NEAT1 and miR-335-5p remains poorly understood. In this study, we investigated the effects of NEAT1 and miR-335-5p(More)
BACKGROUND TM4SF1 is overexpressed in pancreatic ductal adenocarcinoma (PDAC) and affects the development of this cancer. Also, multidrug resistance (MDR) is generally associated with tumor chemoresistance in pancreatic cancer. However, the correlation between TM4SF1 and MDR remains unknown. This research aims to investigate the effect of TM4SF1 on(More)
Here, the stable performance of nitrogen removal from digester liquor after partial nitrification was experimentally demonstrated in an up-flow anammox reactor with polyethylene sponge (PE sponge) as a biomass carrier. A high nitrogen loading rate of 8.4 kg-N/m(3)/day with a TN removal rate of 7.6 kg-N/m(3)/day was obtained in this study, indicating PE(More)
