摘要： Green liquor clarification comprising filtering of a flowing suspension containing solids, wherein the suspension is brought into contact with a first filter unit (4), said 5 filter unit (4) comprising one or several filter elements (12) comprising one or several filter bodies (3) having filter channels (33) within the filter bodies (3) with a filtering layer (32), a part of the suspension is forced to pass through the filtering layer (32) from a first/inner surface (32A) to a second/outer surface (32B) of the filtering layer (32) forming a filtrate while the solids substantially remains in a residual part of the suspension forming a slurry and where the filtering layer (32) is made of a membrane material with pores, said pores having a pore size of 0.1-10 micrometer, more preferred 0.1-5 micrometer and most preferred 0.2-1.0 micrometer.
