Abstract

A method to treat hydrolyzate with biological organisms including: discharging hydrolyzate from a pulp washing system; storing the hydrolyzate for first stage of pretreatment; determining a chemical oxygen demand (COD) level of the discharged or stored hydrolyzate; adding a dilution liquid to the hydrolyzate as the hydrolyzate is transferred from the first stage of pretreatment to a second stage of pretreatment; determining an amount of the dilution liquid to be added to the hydrolyzate or a ratio of the dilution liquid to the hydrolyzate based on the determined COD level, and transferring the diluted hydrolyzate with the nutrients to a reactor feed tank where it is combined with a recycle stream from a bioreactor having the biological organisms.
