Optimization of Thermophilic Anaerobic Digestion of Winery Bio-waste by Micro-nutrients Augmentation
Thermophilic anaerobic digestion is a suitable technology to treat agricultural waste because of its higher biogas production, hygienisation effect and solids removal efficiency. Although these benefits, poor effluent quality and instability are encountered in some cases. The anaerobic co-digestion of winery waste and waste activated sludge at 55°C, operating at 23 days HRT and with an organic ...
متن کاملChemical speciation of sulfur and metals in biogas reactors - Implications for cobalt and nickel bio-uptake processes.
This article deals with the interrelationship between overall chemical speciation of S, Fe, Co, and Ni in relation to metals bio-uptake processes in continuous stirred tank biogas reactors (CSTBR). To address this topic, laboratory CSTBRs digesting sulfur(S)-rich stillage, as well as full-scale CSTBRs treating sewage sludge and various combinations of organic wastes, termed co-digestion, were t...
متن کاملRecent advances in metal carcinogenicity*
The carcinogenicity of nickel, chromium, arsenic, cobalt, and cadmium compounds has long been recognized. Nevertheless, the mechanisms involved in tumor formation are not well understood. The carcinogenic potential depends on metal species; major determinants are oxidation state and solubility. Two modes of action seem to be predominant: the induction of oxidative DNA damage and the interaction...
متن کاملMagnetic and Electerical Resistivity Behavior of Amorphous Ni Co P Films
Magnetic and Electrical Resistivity Study of Electroless Amorphous Ternary System (Ni-Co-P) show a qualitative dependence of crystalline phases formed during transformation on the annealing temperature and composition. Electrical Resistivity values increases with increase in cobalt content and samples with higher resistivity show lower temperature coefficients. The Initial increase in magnetiza...
متن کاملChronic and acute effects of nickel and cobalt on chlorophyll a and carotenoids of marine micro algae Nannochloropsis oculata
Algae are among the aquatic organisms that are severely exposed to increasing levels of pollutants, which are becoming a concern in marine ecosystems. Heavy metals are among the compounds for which their increase in high levels causes problems in the structure of algae communities in aquatic ecosystems. In this study, the effect of different concentrations of Nickel (1.5, 3, 4, 6, 8, 12, 15 mg/...
