Abstract
A system and method for reclaiming nutrients from dairy manure includes a centrifuge for separating a liquid fraction of the manure from a solid fraction comprising organic material; a mechanical vapor recompression evaporator (“MVR”) to receive the liquid fraction from the centrifuge and evaporating the liquid fraction by mechanical vapor recompression to produce ammonia-laden water vapor and a concentrated nutrient slurry; a dryer for drying the nutrient slurry to a selected moisture content to be available as an ingredient in compounded fertilizer; and an ammonia stripping tower assembly to receive ammonia-laden water vapor from the MVR and from it to precipitate ammonium sulphate salt and condense water as separate products.
