Implementing bioreactors at larger areas (e.g., &gt; 20 ha vs. &lt; 10 ha) could facilitate treatment of relatively greater flow volumes, and thus greater nutrient loads, even if a notable portion of the annual flow bypasses treatment. For example, a hypothetical bioreactor design flow rate of approximately 1.8 L/s resulted in mean treatment of 40,600 versus 15,300 m³/year at large versus small sites assessed here.
