About the Solution:

The innovative Nijhuis GENIUS solution is based on reliable technological solutions and application knowledge:

AECOMIX-TAURUS Digester: a digester can be integrated into the GENIUS system to produce electricity or Renewable Natural Gas (RNG). It is also possible to directly treat manure from manure storage instead of digesting.

GEA Decanter centrifuge: A decanter centrifuge manufactured and sold by GEA separates the manure into a liquid and solid fraction without the addition of polymer. The solids remains a pure organic fertiliser without any additives.

Flotation unit, type i-DAF: This open flotation unit (GDF) is designed for handling high sludge loadings.The intelligent Dissolved Air Flotation (i-DAF) system is based on the Nijhuis innovative and intelligent aeration system (i-AIRATION) which forms fine air bubbles that support and increase the separation of particles.

Ammonia Recovery, type AECO-NAR: The AECO-NAR is an innovative and stable process which is anticipating today’s challenges in the market and producing ammonium sulphate, to maximize the value of digestate. The market potential for this biobased fertilizer varies per geographical location, but proves to be commercially very attractive. The AECO-NAR is a proprietary chemical process based on the stripping of ammonia. The process is designed to treat digestate, or manure, and consists of a heat exchanger, a CO2 stripper tank, an ammonia stripper and a scrubber.

Membrane systems, type UF and RO: Membrane separation processes are based on a straightforward separation method, whereby specific filters will let water flow through while it retains suspended solids and bigger molecules. The selection of the right type of membranes and working conditions are important to determine the water quality and liquid fertilizer.

Solution Strengths, Weaknesses and Critical Indicators

Anaerobic Digester Associated Technology:

NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.


  • Long usable life and can be run reliably
  • Creates energy and generates environmental credits
  • Requires proper preparation of the feedstock
  • Requires other technologies for energy utilization
  • Requires other technologies for digestate handling
  • Proper feeding & system monitoring is required to avoid system downtime
  • Proven technology for odor control, GHG reduction and pathogen reduction

Newtrient Comments/Opinions:

Nijhuis believes that an increasing number of livestock farms have insufficient land for efficient use of manure nutrients. In order to avoid manure overloading on to the land and forcing the redistribution of livestock,surplus manure has either to be transported to areas with less intensity or needs to be processed for the recovery and utilization of valuable compounds.

For this reason Nijhuis has developed the GENIUS system with a goal of being a cost effective, innovative and sustainable system for the processing of manure into high quality concentrated liquid fertilizer, reusable water and a solid fraction. They believe the liquid concentrated fertilizer has value because it is rich in nitrogen and potassium and can be used to supplement or replace the use of artificial fertilizer. They feel the solid fraction, which is rich in organic nitrogen and phosphates, has value as a soil additive and, depending on the local needs, can be easily transported or made into other products. They feel that the recovered water fraction from the manure can be reused or discharged as surface water.
