typical wastewater temperature
There are three temperature regimes: the mesophilic over a temperature range of 4 to 39Â°C [39.2 to 102.2Â°F], the thermophilic which peaks at a temperature of 55Â°C [131Â°F], and the psychrophilic which operates at temperatures below 4Â°C [39.2Â°F].sychrophiles grow within the range of 0 to 20Â°C (32 to 70Â°F), with an optimum of 10 to 15Â°C (50 to 60Â°F). Mesophiles, which comprise most of the species commonly found in wastewater treatment processes, grow within the range of 10 to 45Â°C (50 to 115Â°F), with an optimum of approximately 30 to 35Â°C (85 to 95Â°F).
