Sludge separator with infiltration package

This technology purifies using the soil. There are different variants of soil-based treatment but the principle is the same. There are gravity systems and pressurized systems with pumping.

Infiltration: The treatment takes place in the natural soil layers.

Biomodules: A reinforcement of the biological purification in which reduces the surface.

Soil bed: The bed is excavated and the soil is replaced with soil bed sand.

In an infiltration system, water is purified by flowing through natural soil layers and spreading through the ground to the groundwater. In the soil, water is naturally purified through biological, physical and chemical processes.

For infiltration to be possible, the soil must be sufficiently permeable and able to transport the water away. The soil must also not be too coarse-grained, as the water will not have time to be purified before it reaches the groundwater. To find out the infiltration capacity of the soil, a test pit is dug and a percolation test is taken.

In case of unsuitable site conditions, the wastewater may need to be pumped to a more suitable location.
