Top® is environmentally sustainable.
Extremely low exhaust emissions (CO2)
The Wet Oxidation process produces low temperature (40-60 °C) gaseous emission (about 10-12% by mass with respect to an incinerator). Reaction gases are cooled and washed, the incondensable gases are burned in a heater. Gas emission from TOP plant are very low, since the gases discharged are substantially carbon dioxide produced during the reaction and oxygen fed in excess with respect to the COD converted.
No harmful emissions
The gases discharged by the plant are only carbon dioxide produced during the reaction and oxygen fed in excess with respect to COD converted. The reaction gases are cooled and washed before leaving the oxidation plant. Reaction conditions (temperature, pH, etc..) do not allow the formation of any hazardous substances (eg. Dioxins).
No fly ashes
Unlike incineration, Wet Oxidation process operates at much lower temperatures and in aqueous medium; the inorganic residue leaves the plant suspended in the liquid effluent and it is recovered by conventional decantation and filtration
- Wet Oxidation does not require any treatments of gas emissions
- Wet Oxidation does not generate any hazardous solid 'gas suspended' to be disposed of through special landfills (fly ash).
High degradation of organic substances
High degradation of organic substances either dissolved or suspended. Liquid effluent totally biodegradable.
Bidegradability of residual COD: Example of wastewater coming from nitration of aromatic compounds.
Bidegradability of residual COD: Example of wastewater coming from nitration of aromatic compounds.
The metals contained in the feeding (no other metals are added such as catalysers for example), at the operating conditions of the process, precipitate as oxides, so the content of such metals in the liquid effluent is drastically reduced.
Inorganic residue (TOP Filler) reuse for industrial and civil construction applications
Inorganic residue of Wet Oxidation treatment becomes TOP Filler, raw material that can be used to build roads. Additional processing can lead to SpheraPor & MicroPor.
Spherapor is a Lightening Structuring material; it is characterized by an open porosity almost nothing as the surface of the sphere shows vitrified. This feature prevents water absorption, whatever the application in which Spherapor is used, thus ensuring the high lightness of the final product. Mechanical strength up to 5 times higher than that of the reference products on the market it is combined with the low specific gravity; lightness and mechanical strenght, as well as a very high chemical inertness, make Spherapor a highly innovative solution for Lightweight Concrete, or Glue, markets particularly for the building field.
