Anaerobic Digestion Wastewater Treatment

The Upward Flow Anaerobic Sludge Blanket or UASB process is a specialist use of anaerobic digestion wastewater treatment. It is quite rare to see, and it is based upon the idea that the particles in any sludge are gradually falling within the liquid they are in.

The use of anaerobic digestion (AD) for wastewater treatment started late in Mexico compared to the European countries or even to North America. The first digester was constructed by 1987 (see Fig. 2). Further development was rather slow since until 1991 the rate of digester's construction remained around one to four reactors per year.

Anaerobic Co-Digestion of Wastewater Sludge: A Review

Anaerobic digestion has been widely employed in waste treatment for its ability to capture methane gas released as a product during the digestion. Certain wastes, however, cannot be easily digested due to their low nutrient level insufficient for anaerobic digestion, thus co-digestion is a viable option. Numerous studies have shown that using co-substrates in anaerobic digestion systems
