Intensiv Filter Himenviro: Waste Disposal
Industry Environmental Solutions
Today mainly dry and quasi-dry methods, the separation efficiency of which is significantly better than the currently applicable limit values, are used in the field of waste incineration. In this, fabric filters play an important role in the overall process and, when used with sorbent mixtures, allow for simultaneous separation of acidic gas pollutants, unburnt aromatic compounds, dioxins and furans, heavy metals, and dust. Unlike waste, sewage sludge cannot be avoided – on the contrary. Better wastewater purification naturally produces more sewage sludge. In the Federal Republic of Germany approx. 10-15% of communal sewage sludge is incinerated. It is frequently highly contaminated with substances that mainly get into the waste gas when treated thermally. Usually, sewage sludge incineration plants are equipped with multi-stage gas cleaning installations for separating bags of dust and acidic harmful gases and for reducing the number of nitric oxides.
