Water Science and Technology, 1983 The influence of the sludge loading rate, the addition of a small amount of granular sludge to the seed sludge and the effect of the NH4+- and Ca2+-concentration in the influent on the pelletization-process of anaerobic methanogenic sludge in UASB-reactors were studied. Two different types of sludge granules can be obtained with VFA's as feed-solution.

Anaerobic Treatment of Concentrated Black Water in UASB Reactor at a Short HRT [PDF]
, 2010 This research describes the feasibility of applying a UASB reactor for the treatment of concentrated black (toilet) water at 25 °C. On average 78% of the influent load of COD at an HRT of 8.7 days was removed. Produced methane can be converted to 56 MJ/p/

Anaerobic digestion and the denitrification in UASB reactor
Journal of Urban and Environmental Engineering, 2008 The environmental conditions in Brazil have been contributing to the development of anaerobic systems in the treatment of wastewaters, especially UASB - Upflow Anaerobic Sludge Blanket reactors. The classic biological process for removal of nutrients uses three reactors - Bardenpho System, therefore, this work intends an alternative system, where the ...
