The filters are obtained from standpipe piezometers on which slots are made perpendicular to their axis using disk cutters; the width of the cuts (slots) allows light through and can be configured according to the granulometric curve.
The amount and arrangement of the lights on the filter wall is designed to maintain good mechanical resistance.
