Abstract: The present invention relates to a process for the treatment of industrial alkaline streams comprising sulfide and carbonate, comprising the steps of: a) providing an industrial alkaline stream comprising sulfide and carbonate; b) supplying the industrial alkaline stream to a bioreactor comprising sulfide oxidizing bacteria and removing sulfide from the industrial alkaline stream by subjecting said stream to sulfide oxidizing bacteria in the presence of oxygen, and supplying a pH adjustment agent to the bioreactor to maintain a pH in the range in the range 8 to 11, to oxidize the sulfide to elemental sulfur, c) withdrawing from the bioreactor a treated industrial alkaline stream comprising elemental sulfur, wherein a portion of the sulfide oxidizing bacteria is removed from the bioreactor and mixed with the industrial alkaline stream prior to supplying the industrial alkaline stream to the bioreactor in step b).

Abstract: The invention discloses a method of controlling a pulping process wherein wood chips are conveyed to an impregnation vessel and/or to a digester where said wood chips are treated with a liquor comprising chemicals. According to the method of the invention a ratio between a measured, actual mass flow of moisture wood chips to an impregnation vessel or to a digester and an estimated mass flow of dry wood chips conveyed to the impregnation vessel or to the digester is calculated. Said ratio is used to control the pulping process. The method makes it possible to control e.g. the supply of chemicals, the liquor to wood ratio and the pulping temperature on-line, in a feed-forward manner.
