SeoFoss - OPTIMIZATION OF BIOGAS PLANTS SeoFoss is a slurry additive comprising a carefully selected mixture of special minerals providing an excellent ion exchange effect. The ingredients in SeoFoss have the finest particle sizes in the market. This provides an excellent effect by enlarging the particles’ surface area and enhancing ion exchange, thus creating a homogeneous and liquified biomass. It is difficult for the slurry to mix with dry matter because of the surface tension in the slurry. This means re- duced homogeneity. DRY MATTER LIQUID PHASE DRY MATTER Uniform and homogeneous slurry mixing Advantages of using SeoFoss in biogas plants • More homogeneous biomass with less sediments • Binds ammonia in the biomass – improved nitrogen yield • Less odor • Simplifies stirring of the tanks, which saves energy • Supports the functioning of bacteria - increased gas production
