1. Fe3O4@C core-shell nanoparticles as adsorbent of ionic zinc: evaluating of the adsorptive capacity
Zinc is an important chemical element in many metabolic mechanisms at low concentrations, but can be toxic when administrated in doses higher than 500 µg·g-1 or 3 mg·L-1. This metal has been detected in many aquatic environments due to several industry activities and swine manure effluents. Thus, the contaminant removal of water and wastewater has been a

2. Recovery of ammonia from anaerobically digested manure using gas-permeable membranes
ABSTRACT Nitrogen (N) can be recovered from different types of wastewaters. Among these wastewaters, anaerobically digested swine manure (digestate) has the highest N content in ammonia form (NH3). It is desirable to reduce N in digestate effluents to safely incorporate them in arable soil in N vulnerable zones (NVZ) and to mitigate NH3 emissions during N la

3. The behaviour of an anaerobic baffled reactor (ABR) as the first stage in the biological treatment of hog farming effluents
This present paper reports a study of the efficiency of an anaerobic Baffled Reactor (ABR) composed of three chambers working as the first stage of a biological treatment system for swine wastewater, over a period of 116 days. The average value of the volumetric organic loading rate (VOLR) was 17.8 kgCODtotal m-3 d-1, the biological organic loading rates (BO

4. Nitrogen removal from swine wastewater by combining treated effluent with raw manure
Effluents from swine raising can be harmful to the environment if not correctly managed. Nitrogen (N) is usually the main element present at high concentrations in the effluent. Since the use as biofertilizer is not always a feasible alternative, the treatment of swine wastewater is necessary. Variations in N species and water solubility make the treatment d

5. Comparação de três metodologias para quantificação de Salmonella sp. em fluentes de sistemas de tratamento de dejetos.
O aumento da produção suinícola trouxe consigo uma grande quantidade de dejetos que, muitas vezes, são destinados à agricultura ou piscicultura. Sendo os suínos, na maioria das vezes, portadores assintomáticos de Salmonella sp., excretam a bactéria nas fezes. Desta forma, no meio ambiente torna-se uma importante fonte de transmissão e, consequenteme

6. Aplicação de adsorção para remover amônia de efluentes suinícolas pré-tratados
The aim of this work is to evaluate the use of natural zeolites to remove the NH4+ that remains in effluents from swine facilities which were submitted to physico-chemical and biological treatments. Experiments were made in batch made adding 5% (w/w) of adsorbent (0.6-1.3 and 3.0-8.0 mm) to synthetic and real swine facilities effluents. The results show that

7. Efeito de antibióticos utilizados em suinocultura sobre a digestão anaeróbia de efluentes / Effect of antibiotics utilized in swine culture on the anaerobic digestion of effluents
The anaerobic systems for wastewater treatment are viable for several reasons, such as low cost and energy use of the biogas generated. However, the anaerobic digestion process is not yet completely understood, mainly due to the lack of knowledge about the toxicity of the anaerobic microbiota present in the sludge with respect to several compounds. In the ca

8. DIFFUSE POLUTION BY SWINE WASTEWATER APPLICATION IN SOIL CULTIVATED WITH SOYBEAN UNDER SIMULATED RAIN CONDITION / PoluiÃÃo difusa decorrente da aplicaÃÃo de Ãgua residuÃria da suinocultura em solo cultivado com soja sob condiÃÃes de chuva simulada
West of Paranà presents as outstanding economical activity the swine activity. The effluent of swine generated in the agricultural properties are known by its high pollutant potential. Usually the effluents are treated and later applied to the soil as manuring form and reuse of water. However, these applications happen without a defined rate that considers

9. A (in) sustentabilidade da suinocultura e a atividade leiteira diante das perspectivas de viabilização sócio-econômica da agricultura familiar no Oeste Catarinense
This assignment is about the economic, social and environmental impacts caused by the concentration of the pig farms, and the growth of the dairy activity in the Catarinense West Region. It was observed that with the concentration of that activity that started in the eighties, there was a severe social exclusion, and hundreds of farmer families were expelled
