Digestate Mixer for the pretreatment of fermentation residues BRT HARTNER DM

Mixing Unit for Pretreatment of Digestates BRT HARTNER DM

For the Optimal Production of Mixes from Digestate, Sewage Sludge or Similar and Structural Material such as Green Waste and Raw Compost

You are operating a biological waste treatment plant? You need to mix moist bio material, difficult organic residue or sewage sludge with structural material? Digestates have to be pretreated before aerobic treatment? You want to produce a ventilatable, almost homogeneous material for the rotting unit with the corresponding air pore volume? Then you need to go for our Digestate Mixer for the pretreatment of fermentation residues BRT HARTNER DM.

The DM Digestate Mixer by BRT HARTNER is used for aerobic treatment - respectively for preparation for the further composting process - of digestates, sewage sludge or similar material. The structureless material is mixed with structural material such as green waste, raw compost or screen overflow.

The advantage of the Mixing Unit by BRT HARTNER: Due to the mixing system of the substrates with mixing rollers in a dynamic material flow, compaction or kneading effects are avoided and the substrate is homogenized and loosened up. The result is optimal starting material for the subsequent aerobic treatment (rotting). By adding structural material and thereby an increase in air pore volume, the decomposing unit is adequately supplied with oxygen at the start. In the course of the rotting process this should additionally be supported by turning the material. Our sister brand BACKHUS has a variety of solutions for this in their product range.

The Digestate Mixer for the pretreatment of fermentation residues BRT HARTNER DM features a high throughput rate at a simultaneously high stability against impurities. Therefore, it is ideally suited both for integration into the automated material flow of continuously operated plans as well as for feeding by wheel loader in batch operated plants.

Composting facilities that are already in operation can easily be retrofitted with the Digestate Mixer
