COMPOST BIOSTABILIZATION

biological gas depuration

Mechanical biological treatment (TBM) of solid waste


The biostabilization is a proceeding for treatment of solid municipal waste
(RSU) that consist in the biodegradation of the organic fraction of municipal waste through the aerobic activation of the microorganism present of the environment and evaporation where is eliminated most of the water through the heat generated from biological process.
This treatment is useful for the undifferentiated waste.
Mechanical biological treatment (TBM) → Trituration of waste → Forced air ventilation.

Advantages

We obtain a material stabilazed, dry and clean omogeneous without smell and percolate liquids residuals.
In the process we obtain a reduction in weight and volume of the RSU treated:
25 – 45% weight – 20 – 25 % volume → Transport
After energetic valorization of the material biostabilized and recovery of ferrous and non ferrous material.

Working system

Receiving tank
The trucks dumps products through the doors moving up and down on receiving tanks. This to avoid the exit of smells the system works with depression and with a curtain of sprayed water on the door entrance.
Trituration
The tank of receivement is equiped with a mobile bed that bring waste onto belt conveyor that deposit them on the triturator.
Biostabilisation
At the exit of the triturators and additional conveyor bring the waste to the doors of the modular cells of biostabilization where through a tripper the waste is dosed to each cell with the support of a shredding system and moving plate is positioned on the cells.

Gas treatment

The biofilter works as a system of biological gas depuration. The pollution material is absorbed from the wooden biomass (wood chips) that are composing the bed of biofilter. The biofilter has got a system of dehumidification in a drainage of liquid, to guarantee a correct functioning.

Dynamic respiration index

Technique that validate the oxygen consumption derived from the biodegradation of organic material waste contained in the biomass without oxygen limitation.
Our technology guarantee that bad smells are reduced to DRI less 1000 mg O 2 /kg SV h as per European Union regulation.

Possible use

At exit of area of biostabilization, one electro-hydraulic press will densify, if necessary, the biostabilized waste in pressed balls to be used in:
Landfill at high density: Density 0,4 -0,5 TN/m3 after pressing – Dried material, clean sanitized, without smells and liquame.
Residual derived fuel: Separation of metals and no metals – Separation on vibrating table related to the particelle dimension.
