Abstract
An apparatus for recovering nutrients from digestate comprises one or more solid-liquid separation steps, and dryer, an ammonia stripping device, and an evaporator. In a process, digestate is separated into a solids portion and a liquid portion. Ammonia is stripped from the liquid portion and converted into an ammonium solution or salt which may be used as, or blended with, a fertilizer product. At least part of the remaining liquid portion is concentrated to produce brine. The brine is mixed with the solids portion. The mixture is dried and may be used as, or blended with, a fertilizer product.
