Abstract [en]

The present-day treatment of pulp and paper mill effluents can be significantly improvedby incorporating biogas production in the context of industrial symbiosis. In this work anew industrial symbiosis concept is presented, the focus being on modelling it in view ofprocess optimization, design improvement and adoption by the pulp and paper industry.The concept consists of a first stage in which pulp and paper mills effluents are treatedby high-rate anaerobic digestion in external circulation sludge bed (ECSB) reactors toproduce biogas. In the second stage the removal of organic matter contained in thedigestate stream occurs through aerobic activated sludge treatment, aiming to achievemaximum sludge production with minimum aeration requirements. This sludge shouldin the case study then be co-digested with fish-waste silage to yield methane for energyproduction, nutrients-rich reject water that can be recycled to the activated sludgetreatment for optimum microbial activities and, production of nutrient rich soilamendment. The overall research aim is to develop a mathematical model that describesthe relevant process units and the dynamics of the different processes involving organicmatter removal, biogas production and nutrients release. The review overall finds thatan integrated model is required to simulate this concept and should include recentdevelopments in activated sludge, anaerobic digestion and physico-chemical modelling.
