“…The main concern of these systems is the potential environmental impact on air, water, and soil. The large volume of effluent generated by the CAFO must be properly managed to avoid negative environmental impacts (Palhares 2011;Kunz et al 2012).…”

Inactivation of pathogens present in animal manure prior to land application has justified the use of advanced technologies. However, some alternatives are expensive or not effective due to the organic material and suspended solids present in the effluent (e.g., ozone, UV light). The use of hydrated lime (calcium hydroxide, Ca(OH) 2 ) is an attractive wastewater treatment option due to the ability of lime to kill pathogens and to extract phosphorus from manure at an alkaline pH. The present study aimed to evaluate the soluble phosphorus removal and pathogen inactivation (Escherichia coli, Salmonella enterica serovar typhymurium and Porcine circovirus type 2), in the liquid fraction and in the solid generated after Ca(OH) 2 addition in swine wastewater, exposed for 3 and 24 h at different pH conditions: 9.0, 9.5, and 10.0. The results showed the efficiency of pH elevation with Ca(OH) 2 in the removal of soluble P at pH 9.0 and the total inactivation of E. coli, Salmonella, and P. circovirus type 2 at pH 10.0. The liquid fraction (reuse water) could be safely used for cleaning the swine production facilities, and the solid fraction (precipitated P) could be used as a secondary product and fertilizer.

“…Os principais componentes dos DS que são responsáveis por este impacto são o nitrogênio, o fósforo e alguns microminerais, como o zinco e o cobre (SARDÁ et al, 2010). A principal explicação para este fato é a aplicação intensa de DS contendo grande quantidade de nutrientes que resultam na saturação do solo, dificultando sua capacidade de absorção e retenção, tornando-os assim menos férteis (NUNES et al, 2011;KUNZ et al, 2012).…”

A suinocultura é uma atividade econômica de destaque no agronegócio brasileiro. Entretanto, a geração de efluentes em grande quantidade com potencial de poluição elevado caracteriza um obstáculo para o crescimento desta atividade. Diante deste cenário, este trabalho objetivou contextualizar a importância ambiental, econômica e sanitária do tratamento das dejeções suinícolas e descrever a tecnologia da biodigestão anaeróbia aplicada neste âmbito. A adoção da biodigestão anaeróbia se apresenta como uma alternativa eficiente para o tratamento destes dejetos. O uso de biodigestores promove um ambiente com condições anaeróbias que possibilita o desenvolvimento de bactérias hidrolíticas, acidogênicas, acetogênicas e metanogênicas que promovem a degradação da matéria orgânica e a reciclagem de nutrientes culminando na geração de subprodutos de valor agregado: biogás e biofertilizante, com desdobramentos ambientais, sanitários, econômicos e sociais positivos.

“…Automated approaches, developed using probes installed directly in the river (Rozemeijer et al, 2010a;Macintosh et al, 2011;Cassidy and Jordan 2011;Dåbakk et al, 1999;Glasgow et al, 2004;Zhu et al, 2010;Yang et al, 2008), or using online instrumental devices in which continuously pumped water is injected (Rozemeijer et al, 2010b;Zabiegala et al, 2010;Jordan and Cassidy, 2011), are alternatives to sampling methods requiring human intervention. Several papers have been published over the last decade reporting existing devices mostly focused on monitoring dissolved N or P and organic matter (Clough et al, 2007;Kunz et al, 2012;Aubert et al, 2013b;Escoffier et al, 2016). A recent overview of the potential of available conductivity, dissolved oxygen and carbon dioxide, nutrients, dissolved organic matter and chlorophyll in situ probes is given by Rode et al (2016).…”

Abstract. Our understanding of hydrological and chemical processes at the catchment scale is limited by our capacity to record the full breadth of the information carried by river chemistry, both in terms of sampling frequency and precision. Here, we present a proof-of-concept study of a "lab in the field" called the "River Lab" (RL), based on the idea of permanently installing a suite of laboratory instruments in the field next to a river. Housed in a small shed, this set of instruments performs analyses at a frequency of one every 40 min for major dissolved species (Na + , K + , Mg 2+ , Ca 2+ , Cl − , SO 2− 4 , NO − 3 ) through continuous sampling and filtration of the river water using automated ion chromatographs. The RL was deployed in the Orgeval Critical Zone Observatory, France for over a year of continuous analyses. Results show that the RL is able to capture long-term fine chemical variations with no drift and a precision significantly better than conventionally achieved in the laboratory (up to ±0.5 % for all major species for over a day and up to 1.7 % over 2 months). The RL is able to capture the abrupt changes in dissolved species concentrations during a typical 6-day rain event, as well as daily oscillations during a hydrological low-flow period of summer drought. Using the measured signals as a benchmark, we numerically assess the effects of a lower sampling frequency (typical of conventional field sampling campaigns) and of a lower precision (typically reached in the laboratory) on the hydrochemical signal. The highresolution, high-precision measurements made possible by the RL open new perspectives for understanding critical zone hydro-bio-geochemical cycles. Finally, the RL also offers a solution for management agencies to monitor water quality in quasi-real time.
