“…However, sensitive watercourses also can be in more remote locations, receiving P discharges from smaller WWTPs. Further, wastewater from smaller communities is often treated less rigorously (Molinos-Senante et al, 2014;Lutterbeck et al, 2017) and the potential negative impacts of P release from small treatment works may be underestimated (Bowes et al, 2015;May et al, 2015).…”

The removal of phosphorus (P) from domestic wastewater is primarily to reduce the potential for eutrophication in receiving waters, and is mandated and common in many countries. However, most P-removal technologies have been developed for use at larger wastewater treatment plants that have economies-of-scale, rigorous monitoring, and in-house operating expertise. Smaller treatment plants often do not have these luxuries, which is problematic because there is concern that P releases from small treatment systems may have greater environmental impact than previously believed. Here P-removal technologies are reviewed with the goal of determining which treatment options are amenable to small-scale applications. Significant progress has been made in developing some technologies for small-scale application, namely sorptive media. However, as this review shows, there is a shortage of treatment technologies for P-removal at smaller scales, particularly sustainable and reliable options that demand minimal operating and maintenance expertise or are suited to northern latitudes. In view of emerging regulatory pressure, investment should be made in developing new or adapting existing P-removal technologies, specifically for implementation at small-scale treatment works.

“…Installation of P removal technology in large wastewater treatment plants become quite common [7]. However, receiving P discharges from small wastewater treatment plants is often treated less rigorously; and the potential adverse effects of phosphate that results from small communities may be underestimated [8].…”

Study of Biomass Bottom Ash Efficiency as Phosphate Sorbent Material

et al. 2019

Excessive richness of nutrients in water bodies such as rivers, lakes and ponds lead into deterioration of aquatic life as a results of dense growth of algae. Phosphate is one of the main nutrients that should be controlled to prevent this serious issue. Utilizing low cost material as a phosphate sorbent is offering a treatment method characterized as a sustainable solution. In this study the efficiency of biomass bottom ash BBA as phosphate sorbent material from aqueous solution is investigated. Batch experiments were undertaken, in which a particular mass of BBA was brought into contact with the phosphate solution. The experiments studied the influence of pH (different phosphate solutions were prepared with pH range 4 to 8), temperature (adsorption capacity measured at the temperature range of 10 to 30 °C), and contact time. In addition, the adsorption isotherm models were also applied to better understand the mechanism of phosphate sorption by BBA. The results revealed that the bonding between the cations (BBA surface) and anions (phosphate solution) is significantly affected by the pH of the solution. BBA presents an excellent phosphate sorption, especially, at low pH value and temperature around 20 o C. The method of this research can be adopted as a followed strategy for examination the capability of selected material for phosphorus removal from wastewater.

“…Estudos de ACV e ACCV de WC realizados anteriormente não envolveram a análise de WCs aerados artificialmente (DIXON;SIMON;BURKITT, 2003;MA-CHADO et al, 2006;LOPSIK, 2013;BROWN, 2016;LUTTERBECK et al, 2017;MC-NAMARA, 2018). Além disso, há uma carência de dados de inventário de sistemas de tratamento de esgoto brasileiros, já que a maioria dos estudos de ACV de sistemas de tratamento de esgoto foi realizada no exterior (GUTIERREZ, 2014).…”

Sistemas de tratamento de esgoto, apesar de possibilitarem a eliminação ou redução de poluentes e substâncias indesejadas presentes nos efluentes, também ocasionam impactos ambientais. Uma das ferramentas que podem ser utilizadas para avaliar o desempenho ambiental de sistemas de tratamento de esgoto é a avaliação do ciclo de vida (ACV), que pode ser complementada pela avaliação do custo do ciclo de vida (ACCV), que permite calcular o custo do ciclo de vida de um projeto. No presente estudo, a ACV e a ACCV foram utilizadas com o objetivo de analisar os potenciais impactos ambientais e custos de duas configurações de sistemas-piloto de tratamento de esgoto descentralizados e de pequena escala envolvendo wetlands construídos (WC) com e sem aeração. A modelagem dos sistemas e os cálculos envolvidos na avaliação dos impactos do
