Larox Filters Provides the Optimal Solution for processing Green Liquor and Green Liquor Dregs from a Clarifier Circuit

LAPPEENRANTA, FINLAND - February 9, 2007 - A new leaflet from Larox describes
how the combination of the Larox C Series Automatic Pressure Filter together
with the Scheibler A Series Polishing Filter to provide a virtually solids free
Green Liquor for the recausticizing process and dry washed dregs for easy
disposal with a residual Na2O in the dregs cake be below 1.0%. 

The combination of the Larox "C" Series Automatic Pressure Filter together with
a Scheibler "A" Series Polishing Filter provides a superior solution for the
removal of dregs from a Green Liquor Circuit that uses a clarifier compared to
all alternative technologies. 

The "C" Series Automatic Pressure Filter can be operated with or without cake
washing as needed, but when cake washing is used it can reduce the residual
Na2O levels in the dregs cake to < 1.0% w/w basis. At the same time the
Scheibler "A " Series Polishing filter can produce a clarified green liquor
containing single-digit (<10) parts per million solids in the exiting stream.
