The digestate that forms in the AD is sent to a solid-liquid separator (SLS) where larger solids are removed to be used as animal bedding. The SLS enables the recovery of approximately 30% of the P, or 3.8 tonnes/yr, which is removed in the solids stream. Meanwhile, the liquid stream is fed to a series of b-PBRs where it is used as a nutrient-rich medium to grow the cyanobacteria. In addition to the digestate, an additional nitrogen source (urea) can also be fed to the reactors (if necessary) to provide any additional N required to meet the nutrient needs of the cyanobacteria. Growth is assumed to be light-limited and is simulated as described by Clark et al. After harvesting, the culture enters a flocculation system where selfflocculation is induced. The outlet of this unit is fed to a lamella clarifier where the flocs settle out of solution and are then sent to a pressure filter to produce a concentrated biomass solution. This solution is transferred to a thermal dryer that completes the moisture removal and yields a dry cyanobacteria biomass product. The biomass-free water exiting the lamella clarifier and pressure filter is mixed and 95% is recycled back to the b-PBRs while the remaining 5% is purged to prevent the buildup of impurities in the process. While the manure supplies water to the process, this is not sufficient in the baseline process to compensate for water losses in the purge and thermal dryer. As a result, an additional stream of freshwater must be fed into the b-PBRs.
