An extraction manifold for extracting digestate from a covered lagoon digester includes a digester vessel being shaped generally as a rectangular prism lacking an upward facing face and having a floor sloping generally downward from an intake face to an extraction face of the digester vessel. The intake face and extraction face are oriented vertically, situated in opposed relation on a longer horizontal axis. Each effluent pipe terminates in an extraction nozzle on one end and an independently addressable actuatable valve on the opposite end. Each actuatable valve communicates with a manifold plenum such that actuation of the valve draws digestate from the floor in a region of the floor adjacent to the extraction face and in proximity to the extraction nozzle. A valve controller actuates valves to remove digestate from the region of the floor adjacent to the extraction face. The valve controller includes sensors to monitor biogas production.
A method and an apparatus for receiving manure from a vacuum truck, as that manure is collected from alleys of a dairy barn, includes receiving the manure in a mixing basin. The received manure is diluted in the mixing basin with a jet of water discharging a sufficient volume of water to form a sand-laden manure flow having a velocity of over 3 feet per second and dilute the received manure into a sand-laden manure suspension of less than seven percent manure solids. The resulting sand laden manure suspension is conducted into a vestibule of a sand settling lane to slow the flow of the sand laden manure suspension to enter a sand settling lane at a velocity of less than 1.25 feet per second. Sand is collected in the sand settling lane.

To produce fertilizer, a system and method concentrates manure slurry in a mechanical vapor recompression evaporator ("MVR") having a heat exchanger. The MVR receives the manure slurry within a first side to evaporate ammonia laden- water vapor from the slurry, leaving a nutrient concentrate. A compressor raises the evaporated ammonia-laden water vapor to a higher energy state. Within a second side of the heat exchanger, the compressed water vapor conveys heat to the slurry. Ammonia-laden water condenses in the second side at a process temperature to be conveyed to an ammonia stripping tower where the ammonia- laden water is dispersed into ammonia-laden water droplets. In the tower, a flow of air is directed across a surface of the ammonia-laden water droplets, the process temperature having been selected to promote the escape of ammonia gas from the ammonia-laden water droplets, the flow of air provided to entrain ammonia gas in the flow.
