MEDIA-WIND
Fill media for trickling filters
MEDIA-WIND IS A REVOLUTIONARY RAMDOM FILL MEDIA
MEDIA-WIND's geometry has been developed in order obtain extensive wet surface bed compared to their volume.
MEDIA-WIND allows therefore hydraulic applicable surfaced loads. The height permeability and strong hydraulic applicable load minimize any risk of stoppage of the bed, even in case of high specific organic load.
Isotactic PP is a polymer with excellent chemical and mechanical characteristics.
The material employed and the geometry of MEDIA-WIND grant a high compression resistance. In bed-heights up to 6 metres, the most compressed layers undergo a deformation lower than 1-2%.
RULES:
• Sewage has to be clarified and homogenized.
• Decantation prior to effluent recycle.
• Incoming sewage concentration of circa 2-7Kg BOD5/CM of filling admited.
It is good practice to recycle in order to obtain the correct surface load. Incoming sewage BOD5 is related to BOD5 requested by effluent with optimum value of 250mg/L. (except first stage percolaters).
This limits are common to taut fillers which are less subject to stoppage thanks to their geometry.
