Anaerobic membrane bioreactors (AnMBRs) enable high space loading by retaining solids selectively through microfiltration membranes. For organic industrial wastewaters, this offers an alternative to lagoons and granule based high-rate anaerobic treatment due to excellent effluent quality, high tolerance to load variations, and ability to produce a solids free effluent for the purposes of reuse. While there has been extensive work on low-strength and low solids effluent, there has been limited application in high-solids, high fats systems such as slaughterhouse wastewater, which are a key application. A 200 L AnMBR pilot plant operated at 2 Australian cattle slaughterhouses consistently removed over 95% of chemical oxygen demand (COD) from the wastewater. Virtually all degradable COD was converted to biogas, 78–90% of nitrogen and 74% of phosphorus in the wastewater were released to the treated permeate as ammonia and phosphate, respectively; which would enable subsequent nutrient capture. The mass loading rate limit of 3–3.5 g COD L−1 d−1 is imposed by the active biomass inventory, with this in turn limited to 40 g L−1 (TS) by the need to manage membrane fouling control.
