Olive mill wastewater valorisation through phenolic compounds adsorption in a continuous flow column

Sequential pressure-driven membrane operations to recover and fractionate polyphenols and polysaccharides from second racking wine lees

“…Consequently, in the last few years, a myriad of sources have been investigated to supply the growing market of natural antioxidants: olive mill wastewaters [7][8][9], apple pomace [10],…”

Integrated technological and management solutions for wastewater treatment and efficient agricultural reuse in Egypt, Morocco, and Tunisia

“…This phase is dedicated to the development and adaptation of technologies for WW treatment and water efficiency in agriculture to the local context of the 3 MACs. To maximize the impact of MADFORWATER, 4 water categories are taken into consideration: Municipal WW (MWW), which represents 82%–92% of the total WW produced; only 50% of MWW produced is currently treated in the target MACs. Textile WW (TWW), a relevant type of industrial WW in the 3 MACs (textile production provides 6% of GDP in Egypt, 7% in Morocco and Tunisia). Agro‐industrial WWs, in particular olive mill WW (OMWW) and fruit and vegetable packaging WW (FVPWW), due to their quantitative and qualitative relevance in all 3 MACs and to the lack of cost‐effective, industrial‐scale processes for their treatment (Frascari et al ). Drainage canal water (DCW) of the Nile Delta (Egypt), a mixture of freshwater from the Nile river and water from irrigation drains, with minor contributions from untreated or partially treated municipal and industrial WWs; DCW is extensively used for irrigation (11 × 10 9 m 3 /y; FAO 2017). …”

Recovery of phenols from autohydrolysis liquors of barley husks: Kinetic and equilibrium studies

“…Thus, the adsorption process is preferred because it is a low-cost separation technique, applicable for industrial scale processes, with high adsorption capacities, possible recovery of the adsorbed molecules and easy regeneration (Abdelkreem, 2013;Kammerer et al, 2011;Soto et al, 2011). Resins have been applied for the adsorption of phenolic compounds and hydroxytyrosol from olive oil mill wastewater (Agalias et al, 2007;Frascari et al, 2016;Petrotos et al, 2016Petrotos et al, , 2013, hydroxytyrosol and tyrosol from fermentation brine wastewater (Ferrer-Poloniom et al, 2016), spinacetin and patuletin from spinach leaves (Aehle et al, 2004), polyphenols from kiwifruit juice (Gao et al, 2013), limonin and naringin from orange juice (Ribeiro et al, 2002), hesperidin from orange peel (Di Mauro et al, 1999), anthocyanins from roselle (Chang et al, 2012), narirutin from a water-extract of Citrus unshiu peels (Kim et al, 2007), genistein and apigenin from extracts of pigeon pea roots (Liu et al, 2010), anthocyanins and hydroxycinnamates from orange juice (Scordino et al, 2005), chlorogenic acid and apigenin-7-O-glucoside from artichoke wastewaters (Conidi et al, 2015), catechin, epicatechin, epicatechin gallate, epigallocatechin gallate and caffeine from green tea (Jin et al, 2015; MARK 2016), catechins and theaflavins from black tea (Monsanto et al, 2015). The study of plant extracts is complex due to the interactions of other plant constituents, which could has an impact on phenolic binding (Bretag et al, 2009;Kammerer et al, 2010).…”
