Membrane fouling and cleaning in lignocellulosic biorefineries
Abstract
IntroductionThe pulp and paper sector is a key global industry. Presently, pulp mills prioritize the production of pulp, fibers, and electricity. By transforming traditional pulp mills into lignocellulosic biorefineries, they can become a key element of a future, circular bioeconomy. To accomplish this, pulp mills need to close their loops and optimize the use of the lignocellulosic feedstock, not just for pulp and fiber production but also for co-production of biochemicals, biofuels, and other high-value materials. Membrane processes can play an important role in this transition as electrifiable, low energy and high-selective separation processes. A key challenge and important cost factor when using membrane processes is membrane fouling and subsequent membrane cleaning. In this lecture two studies on membrane fouling and cleaning with reference to two process streams in the pulping industry will be presented. Bleaching plant effluent from sulphite pulping processIn this study tubular polymeric UF membrane used for several months for concentration of bleach plant effluent in a magnesium sulphite pulp mill were investigated. The initial analysis of the fouling layer on the membrane was conducted in combination of scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) and attenuated total reflection Fourier transformed infrared spectroscopy (ATR-FTIR). Additionally, high-performance anion-exchange chromatography coupled with pulsed amperometric detection (HPAEC-PAD) and heteronuclear single quantum coherence 2D nuclear magnetic resonance spectroscopy (HSQC-2D-NMR) were used. The comprehensive analysis showed that a 4.5 µm thick fouling layer consisting mainly of magnesium had been formed on the membrane during its lifespan. Based on this, alkaline membrane cleaning was tested on samples of the fouled membrane and SEM-EDS analysis was conducted before and after cleaning. Before the analysis the membrane samples were placed for 1h and 20 h in the alkaline cleaning solution. The subsequent ...
