Abstract

5 ila 50 arasinda yatay ve/veya çapraz akis filtre zeminlerine sahip dispersiyonlarda uçucu tortu miktarinin azaltilmasi için karsi akis kolonu içinde yatay filtre tabanindaki özel serbest delik yüzeyi %2 ila 25 ve çapraz akim filtre zemininde %1 ila 10, yatay filtre tabanlarinda ortalama delik çapi 10mm ila 50 mm ve çapraz akim filtre tabanlarinda ortalama delik çapi 2mm ila 10 mm civarindadir.In the dispersions with 5 to 50 horizontal and / or cross flow filter floors, the special free hole surface in the horizontal filter base 2 to 25% in the flow column and 1 to 10% in the cross flow filter floor and the average hole diameter in the horizontal filter bases to reduce the amount of volatile sediment. Average hole diameter in the range of 10mm to 50mm and cross flow filter bases is around 2mm to 10mm.
