Esmil Process Systems have gained vast experience in the field of Anaerobic Digestate treatment. From bench scale studies to on site pilot plant trials through to full scale plant supply, Esmil will offer state-of-the-art solid-liquid phase separation using membrane processes.
Using integrated Esmil system packages, the AD operator can now convert digestate into 3 valuable process outputs. Nearly 2/3 of the digestate is recovered as pure water which can be recycled or safely disposed to watercourse. The separated solids are available as a stackable, phosphate rich compost which is both valuable and marketable. The rest of the liquid presents as a nitrogen rich super fertiliser which is in demand in the agricultural sector.
Application of this treatment system eliminates or significantly reduces digestate truck off costs and spreading costs are eliminated. Zero Liquid Discharge digestate treatment is possible on sites where there is waste heat available.
