13. PERFORMANCE OF TIFTON 85 GRASS UNDER FERTIRRIGATION WITH SLAUGHTERHOUSE WASTEWATER
ABSTRACT: The aim of this study was to evaluate the performance of Tifton 85 grass cultivated in soil columns and fertilized with different wastewater doses of swine slaughterhouse. The experiment was conducted in the Environmental Engineering Center and Sanitary of UFLA/MG in PVC columns filled with Dark Red Latosol (Oxisol) and randomly distributed. The tr

14. SOIL MESO- AND MACROFAUNA IN TWO SOYBEAN CROPS AFTER SWINE WASTEWATER APPLICATION
ABSTRACT Hog raising generates a large amount of residues that is commonly discarded into the soil as fertilizer even with environmental risks. In this context, the aim of this study was to assess the application effects of different doses of swine wastewater (SW) associated with mineral fertilization on the abundance and diversity of organisms of soil meso-

15. CHARACTERIZATION OF CLOGGING MATERIAL FROM HORIZONTAL SUBSURFACE FLOW CONSTRUCTED WETLAND SYSTEMS
ABSTRACT This study aimed to characterize the material composition responsible for clogging the porous medium of horizontal subsurface flow constructed wetland (HSSF–CW) systems, which is detrimental to a proper system operation. Six completely clogged HSSF–CWs were used after treatment of swine wastewater. Operating conditions of these systems were name

16. HYDRAULIC CONDUCTIVITY VARIABILITY IN HORIZONTAL SUBSURFACE FLOW CONSTRUCTED WETLANDS
ABSTRACT Many modifications in hydrodynamic conditions occur inside the bed of a horizontal subsurface flow constructed wetland (HSSF–CW) in operation. Studies on hydraulic conductivity measurement techniques in HSSF–CW are imperative since the monitoring of flow conditions is essential for understanding and controlling its clogging. This study aimed to

17. POTENTIAL OF REDUCTION IN THE EMISSION OF METHANE AND NITROUS OXIDE FROM SWINE WASTEWATER AFTER TREATED BY TWO DIFFERENT SYSTEMS
ABSTRACT Swine wastewater have high pollution load, requiring treatment before its disposal into the environment. Methane (CH4) potentially emitted for such waste is considered 21 times more polluting than Carbon dioxide (CO2), and the nitrous oxide (N2O) is considered 310 times. In this way, projects of the Clean Development Mechanism (CDM) and energy use r

18. Association of swine wastewater and mineral fertilization on black oat production
ABSTRACT Swine wastewater (SW) has high organic load, becoming an important source of macro and micronutrients to plants, promoting the improvement of soil quality and development in various cultures. However, when done without agronomic and environmental criteria, it can cause soil problems, nutrient leaching, water resource damage and plant toxicity. The o

19. Swine manure digestate treatment using electrocoagulation
ABSTRACT Anaerobic biodigestion is an appropriate alternative for the treatment of swine wastewater due to its biogas generation properties and the possibility of its application as a source of energy for heating or electricity. However, digestate can still contain high levels of turbidity, organic carbon and nutrients and must be correctly managed as a biof

20. Biohydrogen production from cassava wastewater in an anaerobic fluidized bed reactor
The effect of hydraulic retention time (HRT) and organic loading rate (OLR) on biological hydrogen production was assessed using an anaerobic fluidized bed reactor fed with cassava wastewater. The HRT of this reactor ranged from 8 to 1 h (28 to 161 kg COD/m³-d). The inoculum was obtained from a facultative pond sludge derived from swine wastewater treatment

21. 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

22. Characterization of an acidification and equalization tank (AET) operating as a primary treatment of swine liquid effluent
This work evaluated the potential of the acidification equalization tank (AET) used as a primary treatment unit, treating the hog farming wastewater. The treatment system consisted of a degritter with a triangular-notch weir, for measuring the flow, a static sieve, and an acidification and equalization tank (AET), an anaerobic baffled reactor (ABR), an upflo

24. BiodigestÃo e co-digestÃo anaerÃbias de cama de frangos com Ãgua residuÃria de suinocultura / Anaerobics biodigestion and co-digestion of poultry litter with swine wastewater
O Brasil apresenta grande potencialidade na produÃÃo de alimentos, porÃm, a produÃÃo em larga escala de grÃos e proteÃna animal tem levado ao aumento da geraÃÃo de resÃduos. Este fato justifica o estudo de prÃticas de reciclagem, tais como a biodigestÃo e a co-digestÃo anaerÃbia de Ãguas residuÃrias e resÃduos sÃlidos oriundos de criatÃrio
