In anaerobic digestion increase in alkalinity indicates increasing in biomass level in the form of sludge is it true. Is any adverse effects operating reactor on higher alkalinity ?

The higher the alkaliity (the lower the acid:alkalinity ratio) in general the lower loading rate on the digester. An underfed digester will produce less methane.

At very high concentrations alkaline salts can be inhibitory or toxic.
