“…[4], but in this study it was also shown for cultures that are accustomed to wood wastewater. As the main reason for the toxicity was considered to be polyphenols [4], the toxic effect on the culture from the paper mill wastewater treatment plant was likely because of the large difference in polyphenol concentrations between softwoods and oak [9], as softwoods are more commonly used in the paper industry. This was corroborated, because all the samples with the sludge treatment performed significantly worse than all the samples without sludge.…”

“…However, we have found no previous studies that were conducted on stormwater that is mainly oak leachate. This has been proven in earlier studies to be harder to degrade and more toxic than other stormwater and wood leachates . This indicates that although the oak leachate has proven to be different from many other wood leachates, its treatability limitations are shared with other wood leachates.…”

The efficiency of biological treatment systems in degrading organic matter is affected by both the available nutrients and the efficiency of the microbial organisms that carry out the degradation. This study assesses whether a wetland treatment system treating stormwater from a wood industrial site faced nutrient deficiency or lacked efficient microbes, and whether addressing these possible problems could enhance the degradation of organic matter in the system. The stormwater was a mix of industrial stormwater, irrigation water and leachate from woodchip piles. The industry mainly processes pedunculate oak, which is known to create a leachate high in polyphenols. This water is currently treated in a pilot-scale wetland system and an aerated lagoon. To study whether the treatability could be enhanced by addition of nutrients (phosphorus, nitrogen, micronutrients), headspace respirometry was used. The effect of adding microbes from a paper mill activated sludge system was also evaluated. Our results showed that all nutrient additions had a positive effect on the treatability of the stormwater. In particular, the addition of nitrogen showed a 12% rise in chemical oxygen demand reduction over 336 h. However, addition of paper mill activated sludge did not enhance the degradation of organic matter; instead, a toxic effect of the stormwater was shown.

“…Flow, chemical characterization and toxicity of the stormwater runoff from this site is described by Kaczala et al (2011Kaczala et al ( , 2012. A detailed description of the water recirculation system at the site is provided by Svensson et al (2012).…”

“…The chemical composition of wood leachate is highly variable and is strongly species-specific. Leachate from oak wood has a high organic content and the colour of the water is correlated with high amounts of polyphenols (PPs) (Svensson et al, 2012). Reducing compounds are often measured in wood leachate by Folin's phenol reagent, correlated to gallic acid and then reported as T&L or polyphenols depending on the author Tao et al, 2005;Svensson et al, 2013).…”

“…It is also often reported to have low pH and to be highly coloured, which is probably connected to the presence of humic acids and different polyphenols (PPs) such as tannic acids or lignins . Wood leachate is also often reported as being toxic to aquatic organisms , such as Daphnia magna , Artemia salina and rainbow trout . Many different compounds in wood leachate, such as tannins, lignin, tropolone, terpene and lignan, as well as low pH , are described as being potentially toxic and this might explain the toxic effects seen.…”

In the present study, we investigated the possibility of treating oak wood leachate with a combined ozone and biological treatment. Wood leachate is characterized by high amounts of organic carbon and is reported as being toxic to aquatic organisms. Ozone was used as a pre‐treatment before using aerobic degradation. The biological treatment was applied for seven days and evaluated using head‐space respirometry. Target pollutant in this investigation was polyphenols in combination with more general parameters, such as chemical oxygen demand (COD), total organic carbon (TOC) and colour. A custom made bubble column reactor was used, 1.5 L of wood leachate was exposed to 0–4 g/L of ozone, corresponding to a specific ozone dose between 0.7–7 g/L O3/g of initial COD. Oak wood leachate was found to be easily degraded by ozone, with >90% of polyphenols degraded. COD was degraded by 73%, TOC by 61% and colour by 97% by ozone. Furthermore, a positive correlation between biodegradation and ozone pre‐treatment was found.
