The effect of temperature on the ability of wetlands to remove nitrates is captured through the relationship of the time constant with temperature, which is given by k = k20θ (T−20) . Here, k20 is the removal rate coefficient at 20 ◦C, θ is the temperature factor whose value in such systems is 1.15, and T is in ◦C. How will the performance of the wetland in Example 20.1 change if the temperature drops to 4 ◦C?
