The alkalinity of natural water is largely dependent on the geology through which it passes and the carbon dioxide in the air.
However, it became evident the importance of using buffering agents in anaerobic biodegradability tests, evaluation of methane potential (BMP) among other similar ones, to guarantee the maintenance of satisfactory environmental conditions of pH and alkalinity and, consequently, the equilibrium and subsistence of various populations of microorganisms present in the anaerobic sludges and responsible for the conversion of complex organic material into methane.

Various physicochemical factors such as water temperature, alkalinity, ammonia, free carbon dioxide, dissolved oxygen (DO), pH and total hardness have strong influence on fish health and their resistance against the pathogens (Welch, 1941; Snieszko, 1974; Plumb et al., 1988; Shresta, 1994; Hossain, 1990).
