MID MIX technique
The MID MIX technology is patented worldwide. In large parts of Europe, the MID MIX is now marketed by VSGM.
Application and capacity
For larger volumes, bespoke installations are designed. Depending on demand, a number of installations can be deployed in parallel.
Different configurations, scalable to very large volumes, can be set up according to the needs of the customer or because of the emergence of a new demand.
The basic process
The installation consists of a number of components. Dewatered sludge is taken from the feed buffer and pre-treated after which it is processed in two reactors. Here CaO is added. Moisture is extracted by exothermic reaction and various chemical and physical processes take place. The core processes that take place in the installation are solidification and molecular encapsulation of heavy metals.
The end product, Neutral, is then cooled. The ventilation air of the process is treated in a baghouse and a scrubber. Approximately 60% of the total input mass is converted into the end product, Neutral. During the process, no residual product remains that needs to be disposed of as waste.
End product Neutral
Neutral can be used as an aggregate in construction, as a soil improver and as a replacement for primary building materials.
