Element in PE HD for wastewater management
Percolation purification also known as sub-irrigation is one of the most used and ancient systems. Its operation is based on wastewater regular distribution from top to bottom over a so called ‘percolation bed’ made of many layers of draining material (stones, plastic materials, ecc…) that permits the reproduction of the same microobiological enviroment that can already be found in nature.
