This issue was triggered in the aeration tank due to the transfer of residual ammoniacal-N from the Extended Granular Sludge Bed (EGSB) reactor through the effluent water. Under the low oxygen nitrification conditions, more oxygen supply facilitated nitrification, thus converting nitrite into nitrate by Nitrobacter. Almost 90 % reduction in TSS was found in the disposal water @ 36-37 ᵒC in the field conditions. However, in the case of high NO 3 -N, low levels of Dissolved Oxygen (DO) are recommended to enhance denitrification in the presence of Nitrosomonas in such a manner that NO 2 -N can squeeze O 2 from NO 3 -N. Similarly, in the case of high NO 2 -N, increased oxygen supply helped to reduce TSS. These strategies reduced TSS-laden N 2 liberation towards the surface of clarifiers. Total Suspended Solids (TSS) in the aeration tank were reduced to almost 90% compared to the initial solids in the aeration tank of the SWTP due to the nitrogen removal. Increased levels of DO (82 %) help to resolve the NO 2 -N accumulation issue in the aeration tank. Sludge volume in the aeration tank was reduced by 62% compared to the initial volume. Similarly, a 50% reduction in SVI30 was observed after 40 days of samples under field conditions, thus showing the removal of nitrogen from the system, which reduced the floatation of TSS.","PeriodicalId":426266,"journal":{"name":"International Journal of Agriculture & Environmental Science","volume":"427 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140482806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They face many constraints, in particular, that of the invasion of exotic species such as Nypa fruticans. The research aim consisted of the characterization of Nipa palm traits in the Wouri estuary. The study was carried out in five points located in the main and secondary streams of the Wouri River. Floristic statements were inside twenty-five plots of 10 m x 10 m, and structural parameters such as the number of individuals, and DBH, with equidistance of 20m, were installed in five sites. The results showed that Nipa palm has an occurrence of 60 % in the studied sites. The higher density was obtained inAkwa-nord with 1309 individuals.ha -1 . The number of leaves significantly differed between the sampling points (K= 6.91; p= 0.03); Youpwe was the site with the higher number. Stalk width also differed significantly between the sites, from 25.2 cm in Essengue to 47.3 cm in Youpwe. Factor analysis revealed more matures and adults in Youpwe, juvenile plants in Essengue, and seedlings in Akwa-nord. This work showed that Youpwe would represent the oldest site and would have been the focus of the propagation of Nypa fruticans in the Wouri estuary.","PeriodicalId":426266,"journal":{"name":"International Journal of Agriculture & Environmental Science","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124944899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
