摘要：The invention relates to a method and equipment for controlling properties ofpaper, which method comprises modelling the effect of the flow of retention agent (Fra)both on the amount of filler in the white water and on the paper ash content (ASH), andthe effect of the flow of filler (Ffi) both on the paper ash content (ASH) and on theamount of filler in the white water. The fulfilled modelling is used to adjust the amountof filler in the white water and the paper ash content (ASH) by controlling simultaneouslythe flow of retention agent (Fra) and the flow of filler (Ffi).
