“…Hemicelluloses were mostly composed of GGM with identified sizes comprised between 0.2 and 20 kDa and some additional molecular weights higher than 100 kDa (Thuvander and Jonsson, 2016). Stack et al, (2014) mentioned that those hemicelluloses with high molecular weights could be formed by adsorption on process water colloidal matter content. This phenomenon could explain hemicelluloses retention observed with 150 kDa UF.…”

Membrane process is a viable option for valuable compounds such as lignin and lignans recovery in aqueous discharges of thermomechanical pulp industries. Recovery of lignin and lignans with continuous mode ultrafiltration/nanofiltration installation has not been studied in detail previously. After flotation used to remove lipophilic matter of pulp mill effluent, the three steps membrane process was composed of a clarification step by a 150 kDa ultrafiltration used to remove suspended matter, followed by two nanofiltrations of 1 kDa and 300 Da to respectively retain lignin and lignans. A techno-economic evaluation of this process has been performed. The process with a plant capacity of 60 m 3 .h-1 was able to produce 12 tons of lignin and 825 kg of lignans per month. The influence of plant capacity between 0.1 and 60 m 3 .h-1 on extracts production cost allows determining a production cost equal or below 10 €.kg-1 as plant capacity reached 10 m 3 .h-1. Valorization of lignin and lignans as parts of the formulas of high added value products could allow thermomechanical plants to head towards 2 biorefinery and cleaner production concepts. Furthemore, the 300 Da permeate possessed the required characteristics to be re used and save fresh water utilization.

During mechanical defibration of wood, a minor fraction of the wood mass is dissolved in the process water. These dissolved substances represent an extra energy demand when they are treated in the mill's wastewater treatment plant. Galactoglucomannan, the main hemicellulose in spruce, can be recovered from thermomechanical pulp mill process water by a process based on microfiltration (MF) and ultrafiltration (UF). The purpose of this work was to study the scale-up of the process from laboratory scale to continuous industrial scale. MF was first studied in the laboratory, and then combined with UF in a continuous pilot process on-site at a pulp mill. The data obtained were used to estimate the cost of the membrane processes for galactoglucomannan recovery which was found to be about e1160 per ton hemicelluloses.
