“…Thus, when PS fermentation liquid was used as the carbon source of enhanced biological phosphorus removal (EBPR), its performance would be better than pure acetic acid. It had also been found that propionic acid-enriched wastewater was much more efficient for EBPR and had a higher phosphorus removal rate in the long-term cultured experiment [30,31].…”

“…7, the phosphorus release and uptake phenomena of the sludge under the optimum RAS pre-concentration ratio operational condition was far more conspicuous than that of the other one. Compared to 0.61, 0.21 and 0.12 mg•g −1 •h −1 under 100% RAS pre-concentration ratio operational condition, the PO − -P (anoxic); ◆ sludge TP anaerobic phosphorus release rate, anoxic and aerobic phosphorus uptake rates of the sludge under optimum RAS pre-concentration ratio operational condition were 2.07, 0.76 and 0.48 mg•g −1 •h −1 , respectively, indicating that more PAOs accumulated in the system sludge [22]. Furthermore, the TP of system sludge increased from 22.6 mg•g −1 (based on VSS) under 100% RAS pre-concentration ratio operational condition to 29.7 mg•g −1 under the optimum RAS pre-concentration ratio operational condition, which also indicated that much more PAOs accumulated in the system sludge [23,24].…”

A pilot-scale, pre-anoxic-anaerobic oxidation ditch was used in this study to treat municipal wastewater with limited carbon source. A novel return activated sludge (RAS) pre-concentration tank was adopted for improving the phosphorus removal efficiency and the effects of RAS pre-concentration ratio were studied. Under the optimal operational condition, the suspended total phosphorus (STP) and the total phosphorus (TP) removal efficiencies were around 58.9% and 63.9% respectively and the effluent 3 4 PO −-P was lower than 0.8 mg•L −1. The reason is that with the optimal RAS pre-concentration ratio, nitrate is completely removed with endogenous carbon source and the secondary phosphorus release is strictly restrained in the pre-anoxic tank. Therefore, the anaerobic phosphorus release and the carbon source uptake by phosphorus accumulation organisms (PAOs) in the sludge, which are extremely important to the phosphorus removal process, can be fully satisfied. Furthermore, the oxidation-reduction potential is proved to be suitable for controlling the RAS pre-concentration ratio due to influent fluctuation and varied conditions. The novel modified system is also beneficial for PAO accumulation.

“…O lodo necessita de um tratamento específico visando corrigir três características indesejáveis do resíduo, tais quais; a instabilidade biológica: o método mais comum para reduzir o teor de material orgânico biodegradável (presente no lodo primário e no lodo aeróbico) é a digestão anaeróbica, sendo também utilizada a digestão aeróbica; a baixa qualidade higiênica: no esgoto sanitário há grande variedade de vírus, bactérias, protozoários, ovos de nematóides e helmintos; o grande volume: como a concentração de sólidos no lodo é baixa, seu volume grande, tornando necessária uma etapa de redução de teor de água [14], tal processo anaeróbio pode durar meses e anos [15].…”

The almost inexistence of sewage collection networks in the city of Manaus, as well as the serious consequences to public health and the environment, makes it necessary to establish sewage networks capable of minimizing and trying to solve such problems. The objective of this article is to implement an Sewage Treatment Plant in the Ayapuá Complex, which does not have a satisfactory sewage treatment system, has only sewage collection boxes and all household waste is disposed of directly In the igarapé of the region, without any type of suitable treatment. And located in the neighborhood of Compensa I, in the city of Manaus, in the state of Amazonas. Using a primary an Sewage Treatment Plant, with a septic tank with anaerobic filter, adopting the design for a residential complex consisting of masonry and reinforced concrete with natural filtering aggregates. The methodology has an applied nature since it seeks to solve the specific problem of a lack of sewage collection network in the city of Manaus, specifically in the western part of the Amazonian capital. Calculation tables and graphs will be used to demonstrate the feasibility of applying the mentioned method in this article. As a result the viability of the implementation of the project of the sewage treatment plant is verified, as well as the reduction of the pollution level of the wastewater in that specific region.
