“…Thus, the binomial time-temperature obtained in this study would be sufficient for disinfection of the sanitary sludge. Jouraiphy et al (2005) observed a significant reduction in the quantities of clostridia in the early months of composting sewage sludge with plant residues; a reduction in bacilli and yeasts was observed when the temperatures were between 60 and 70 ºC, and after 135 days. Fernández et al (2010) and Khalil et al (2011) observed that high temperatures were able to reduce or eliminate pathogenic microorganisms present in the sludge.…”

“…Lower pH values favor the succession of microorganism populations in the composted mass, and stimulate the growth of decomposers of cellulose and lignin, microorganisms that finish the decomposition process (Stentiford and Bertoldi, 2010;Khalil et al, 2011). Organic acids are completely oxidised, stabilising the pH value at the end of the composting process (Jouraiphy et al, 2005;Khalil et al, 2011).…”

ABSTRACT:Sewage sludge (SS) has been widely used as organic fertilizer. However, its continuous use can cause imbalances in soil fertility as well as soil-water-plant system contamination.The study aimed to evaluate possible improvements in the chemical and microbiological characteristics of domestic SS, with low heavy metal contents and pathogens, through the composting process. Two composting piles were set up, based on an initial C/N ratio of 30:1, with successive layers of tree pruning waste and SS. The aeration of piles was performed by mechanical turnover when the temperature rose above 65 ºC. The piles were irrigated when the water content was less than 50 %. Composting was conducted for 120 days. Temperature, moisture content, pH, electrical conductivity (EC), carbon and nitrogen contents, and fecal coliforms were monitored during the composting. A reduction of 58 % in the EC of the compost (SSC) compared with SS was observed and the pH reduced from 7.8 to 6.6. There was an increase in the value of cation exchange capacity/carbon content (CEC/C) and carbon content. .In SSC, helminth eggs were eliminated, making application sustainable for agriculture purposes.

“…Rising water hyacinth in these sites may contain high concentration of nutrients. Some studies have been done on agitated pile composting of different wastes (Parkinson et al 2004;Jouraiphy et al 2005;Kalamdhad 2012, 2013a, b), but there is no information available on composting of water hyacinth collected from different sources. Therefore, the objective of the present study was to assess the nutrients and stability parameters during agitated pile composting of water hyacinth collected from Bharalu River site (BRS), agriculture site (AS), boragaon landfill site (BLS) and industrial site (IS).…”

Background Water hyacinth (Eichhornia crassipes) can cause a diversity of problems due to its fast spread and congested growth. The composting of water hyacinth can reduce the chemical fertilizer application to the agricultural field and problems related to its fast growth rate and also help in nutrient recycling. The present study was carried out on agitated pile composting of water hyacinth collected from four different areas (Bharalu River, Agriculture site, Boragaon landfill site and Industrial site). The nutrients and stability parameters were evaluated during the 30 days of agitated pile composting of water hyacinth mixed with cattle manure and sawdust. The stability of compost was evaluated using respiration techniques (CO 2 evolution and oxygen uptake rate). Results Results showed that nutrients (Na, K, Ca, total nitrogen and phosphorus) were increased significantly in all agitated pile composting. Stability parameters such as CO 2 evolution rate and oxygen uptake rate, biochemical chemical oxygen demand and chemical oxygen demand were reduced significantly during the process. Highest reduction of moisture content (35.2 %), volatile solid (40.5 %), ammonical nitrogen (75.6 %), biochemical oxygen demand (65.3 %), CO 2 evolution rate (78.7 %), and oxygen uptake rate (74.4 %) were observed in the agitated pile of Bharalu River site as compared to other agitated piles. The higher increase of total nitrogen (83.5 %) and total phosphorus (76.0 %) was also observed in the agitated pile of Bharalu River site. Conclusion Addition of optimum amount of cattle manure was highly efficient for making compost of water hyacinth collected from four different sites. Highest content of nutrients was found in compost of water hyacinth collected from Bharalu River site due to availability of nutrients in sewage water. In the final compost of all trials, total coliform and fecal coliform were reduced significantly, which are pathogen indicators in the compost. The best compost quality was found in water hyacinth collected from Bharalu River site.

“…Three combined samples (10 subsamples) of about 100 g of amendments were randomly taken. To characterize amendments, the following chemical and biological parameters were analyzed: a) water content by gravimetric method; b) ash by calcination; c) pH (p/v 1:1); d) electrical conductivity (p/v 1:5); e) total organic C by the wet-digestion method of Walkley and Black modified for plant material [23]; f) soluble organic C by Walkley and Black previously extracted with water at 80ºC [24]; g) humic and fulvic acids (HA and FA, respectively) following [25] ; h) lignin and cellulose content by enzymatic gravimetric methods [26]; i) total N by micro Kjeldahl; j) soluble N by micro Kjeldahl previously extracted with water at 80ºC [24]; k) nitrate and ammonium content by colorimetric methods; l) total Ca and Mg by compleximetric titration methods; m) total P by colorimetric methods ; n) total and exchange Na and K with flame photometric detectors [27]; and o) Escherichia coli and Salmonella spp. abundance following USEPA's recommended methodology [20].…”

Abstract:We analyzed during two garlic crop cycles, the effects of chicken manure and vermicompost on soil chemical and biological properties in an agricultural farm irrigated with municipal wastewater of central-western Argentina. Also we evaluate garlic yield and possible health risks as resulting from the organic amendments and the wastewater use. We found that: a) different doses and types of amendments did not have any significant effects on soil fertility; b) chicken manure and soil before planting, had E. coli and Salmonella spp.; and c) crop yields were quite similar in all treatments, only treatments with 8 Mg ha -1 of both amendments (chicken manure and vermicompost) without N fertilized, were significantly higher than control in both garlic assays. These results are probably the consequence of heavily tilled soils and poor quality of irrigation water with high abundance of enteric bacteria and labile organic matter content. We conclude that to obtain beneficial effects on soil fertility from organic amendment application, wastewater treatment systems must be improved and tillage practices must be reduced.
