		The performance of anaerobic membrane bioreactors (AnMBRs) at psychrophilic temperatures commonly observed in temperate climates (10–24°C) was assessed. A unique aspect of the research was operation at controlled SRT with regular membrane cleaning. COD removal and permeate VFA concentrations were similar at 15 and 24°C and deteriorated at 10°C. As temperature decreased, the COD mass flow to methane decreased and COD mass flows in the permeate and waste sludge increased. At 24°C, rapid membrane TMP increases were not observed while at 15 and 10°C rapid increases occurred at 11.7&amp;nbsp;±&amp;nbsp;0.46 and 7.6&amp;nbsp;±&amp;nbsp;0.45&amp;nbsp;days, respectively, indicating a greater fouling propensity of the mixed liquor at lower temperatures. When the temperature was reduced from 15°C to 10°C in a transient test, CH&lt;sub&gt;4&lt;/sub&gt;&amp;nbsp;production was reduced and VFA concentrations increased. A 2–3 SRT lag in the responses suggested that the delayed response was due to long‐term changes in microbial population. The permeate VFA content in a PAC‐dosed reactor was lower than that without PAC dosing, and PAC addition increased the time to rapid TMP development to 11.3&amp;nbsp;±&amp;nbsp;0.46&amp;nbsp;days from 7.4&amp;nbsp;±&amp;nbsp;0.49&amp;nbsp;days. The primary benefit of PAC addition at low temperatures is enhanced membrane performance.
	&lt;/p&gt;

		Practitioner points
	&lt;/h3&gt;

	&lt;ul&gt;
		&lt;li&gt;
			AnMBRs can produce high‐quality effluents at temperatures of 15°C
		&lt;/li&gt;
		&lt;li&gt;
			Membrane fouling increases as temperature decreases
		&lt;/li&gt;
		&lt;li&gt;
			Bioreactor performance was sustained for 2–3 SRTs after temperature decrease
		&lt;/li&gt;
		&lt;li&gt;
			PAC addition reduced the permeate VFA concentrations
		&lt;/li&gt;
		&lt;li&gt;
			Membrane fouling at 10°C was reduced through PAC addition
		&lt;/li&gt;
	&lt;/ul&gt;
