“…Winery wastewater (WW) and olive mill wastewater (OMWW) are variable in nature but generally characterized by elevated Chemical Oxygen Demand (COD) levels (up to 25 g.L -1 and 170 g.L -1 respectively) and contaminated with (poly)phenolic compounds such as tannins [16,29]. The (poly)phenolics are highly toxic and persist in the environment due to slow biodegradation rates [14,23]. Therefore, strategies must be implemented to reduce the phenolic content of such wastewaters prior to discharge and/or re-use; the latter being of crucial importance in countries subject to water shortages, such as South Africa [10].…”

“…C/TW systems are ideal for developing countries as they are cost-effective, self-sustainable, low in maintenance [10] and effective in treating simple and/or complex organic-rich contaminants such as WW and OMWW [8,14]. The treatment capacity of these systems relies on the synergism between plants, soil and microbial communities, thus involving abiotic (soil substratum) and biotic (plants and microorganisms) remediation mechanisms.…”

“…Phenolic compounds are phytotoxic [14] and the roles of plants in CW COD-removal capacity is controversial [27]. Therefore, in this study the impact of artificial phenolic-laden wastewater on an unplanted CW mesocosm, or biological sand filter (BSF), was investigated with an emphasis on the bacterial communities present in the BSF.…”

Agri effluents such as winery or olive mill wastewaters are characterized by high phenolic concentrations. These compounds are highly toxic and generally refractory to biodegradation.Biological sand filters (BSFs) represent inexpensive, environmentally friendly and sustainable wastewater treatment systems which rely vastly on microbial catabolic processes. This study aimed to assess the impact of increasing concentrations of synthetic phenolic-rich wastewater,

“…The germination index (GI) was determined as has been described previously (Mosse et al, 2010;Zucconi and De Bertoldi, 1981). Briefly, barley seeds were placed in a petri dish on a filter paper moistened with a given water sample, and then incubated for 48 h. At this time, the length of the primary root was measured, and the GI determined by:…”

“…Bioassay techniques offer an alternative and complementary approach to molecular analysis (Mosse et al, 2011) in the screening of effluent waters (Arienzo et al, 2009b;Mosse et al, 2010). The potential phytotoxicity of WWWs has been investigated via seed germination and growth trials, with a strong correlation found between barley seed germination and plant growth, promoting the use of seed germination as a rapid bioassay (Mosse et al, 2010). Whilst bioassay techniques can confirm the toxicity of winery effluent waters, the underlying causes are typically chemical in nature and may not be reflected in general BOD, DOC and pH results.…”

BACKGROUND: Depending on the nature of the pollutants and the level of contaminants, detoxification of various industrial effluents, as well as winery wastewater, might be difficult and/or even impossible to achieve by single conventional biological methods. In such cases, biological processes alone are not able to reach effluent standards for discharge into the environment, and therefore, a pretreatment or post-treatment is required. In this study, winery effluent already treated in a membrane bioreactor (MBR) was subjected to further treatment by a solar Fenton oxidation process, at pilot and industrial scale. RESULTS:The optimum Fe 2+ and H 2 O 2 concentration was found to be 3 mg L −1 and 350 mg L −1 , respectively. Solar Fenton oxidation has been demonstrated to be an effective process both at pilot and industrial scale, yielding after 180 min of photocatalytic treatment removals of COD, DOC and color of about 85%, 62-68%, and ∼80%, respectively. CONCLUSIONS: The combined MBR + solar Fenton process seems to be an effective technology for winery wastewater treatment, that can reduce the organic pollutants in the winery effluent to values below that of the Cypriot discharge limits. Moreover, solar Fenton treatment was proved capable of eliminating the toxicity to D. magna, and significantly reducing the phytotoxicity at values well below the starting values induced by the raw effluent. Industrial-scale solar Fenton treatmentAt the industrial scale, the solar Fenton operation was carried out using 3 mg L −1 of Fe 2+ and 350 mg L −1 of H 2 O 2 , which were the optimum concentrations determined by the pilot-scale experiments. The initial values of COD and DOC of the effluent used for the industrial-scale application were on average 180 mg L −1 and 47 mg L −1 , respectively. wileyonlinelibrary.com/jctb
