Measurement of Granule Density in UASB Reactor
To monitor the granularity of anaerobic sludge, the determination of granule density is vital importance. Granular sludge is the key factor for the efficient operation of upflow anaerobic sludge blanket (UASB) reactor. For this reason several techniques have been proposed. In the proposed algorithm, the granular density was calculated. The granular density was strongly correlated with the VSS/T...
متن کاملAnaerobic Sewage Treatment in a One-stage Uasb and a Combined Uasb-digester System
The potential of a novel technology consisting of a UASB complemented with a digester (UASB-Digester) for mutual sewage treatment and sludge stabilisation under low temperature conditions was investigated. The performance of the UASB-Digester system was compared with a one stage UASB. The UASB reactor was operated at a HRT of 6 hours and controlled temperature of 15°C, the average sewage temper...
متن کاملAnthropological contributions for thinking and acting in the health area and its ethical dilemas Contribuições da antropologia para dilemas éticos da área da saúde
This paper attempts to analyze the way in which the issue of ethics in social research is dealt by institutional commissions based in biomedicine criteria. This discussion is particularly important for Social Sciences in Health, as our projects must necessarily be presented to Committees for assessment. In actual fact, Resolution No 196/1996 issued by the National Health Council establishes thi...
متن کاملon sludge granulation in UASB reactor
Impact of trivalent aluminium (Al) ion, added to the feed of upflow anaerobic sludge blanket (UASB) reactor, was assessed on the granulation of the reactor sludge. The impact on the reactor efficiency in treating chemical oxygen demand (COD) and generating biogas was also simultaneously assessed. It was seen that, at all the three Al concentrations (100, 200 & 300 mg/L) studied, the metal ion f...
متن کاملSulfide Toxicity Kinetics of a Uasb Reactor
The effect of sulfide toxicity on kinetic parameters of anaerobic organic matter removal in a UASB (up-flow anaerobic sludge blanket) reactor is presented. Two lab-scale UASB reactors (10.5 L) were operated continuously during 12 months. The reactors were fed with synthetic wastes prepared daily using glucose, ammonium acetate, methanol and nutrient solution. One of the reactors also received i...
