Technology description

TerraSaline S (ASL) is an innovative technology for producing ammonium sulphateout of any ASL.

The TerraSaline S (ASL) consist of a humidification / dehumidification section, where the ASL is concentrated until the salt (ammonium sulphate) falls out. This wet ammonium sulphate is then dried in the drying section and can be either packed into an integrated bigbag unit or transported to the optional TerraGranulator.A big bag packaging system is also integrated in the container.

Main characteristics:

  • Input material: ASL (Ammonium sulphate solution) of any concentration
  • Output fertilizer: Ammonium Sulphate: 21%N, 24%S, optional added with lime
  • Produce defined fertilizer out of undefined ASL
  • Producing a qualified definedfertilizer (Corn size: 3 to 8 mm)
  • Reducing the needed storage capacity for liquid N-fertilizer (ASL)
  • Environmentally friendly product
  • Product able to be packed in bigbag
  • External heat from a biogas plant or similar
  • Modular system to adjust to needed size
