“…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].…”

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,

“…Among the recent developments, hybrid sub-surface CWs are becoming more popular because of their higher treatment potential (Noorvee et al, 2005;Öövel, 2007;Tuszyñska and Obarska-Pempkowiak, 2008;Justin, 2009;Singh et al, 2009;Kato et al, 2010Kato et al, , 2013Sharma et al, 2012;Serrano et al, 2011;Vymazal and Kröpfelova, 2011). The Performance of a CW is affected by a range of factors such as operational mode (loading rate, continuous or batchload) and environmental conditions (climate, season, temperature etc.)…”

A hybrid sub-surface constructed wetland (CW) system consisting of 2 gravel filled vertical sub-surface (VFa & VFb) beds, each 160 m(2) in size planted with Phragmites australis and a sand filled horizontal sub-surface (HF) bed, 336 m(2) in size, planted with rice was operated from 2007 to 2010 for treating milking parlor waste water in Hokkaido, Japan. Hybrid CW system received huge fluctuations in average yearly inlet loads for TSS (526.0-1259 mg L-1 & 2.7-9.0 g m(-2) d(-1)), BOD5 (1,080-2,114 mg L-1 & 8.4-14.4 g m(-2) d(-1)), COD(1,962-7,085 mg L-1 & 14.5-50.0 g m(-2) d(-1)), TN (116.0-243.0 mg L-1 & 0.8-1.6 g m(-2) d(-1)), NH4-N (54.0-90.0 mg L-1 & 0.40-0.64 g m(-2) d(-1)), TC (1,022-2,215 mg L-1 & 6.0-15.1 g m(-2) d(-1)), TP (15.3-41.7 mg L-1 & 0.11-0.28 g m(-2) d(-1)) during study period. Average yearly purification and removal rates were least fluctuated for TSS (95.7-99.4%); moderately for BOD5 (86.1-95.7%), COD(87.5-96.1%) and TC (79.5-91.3%); highly for TN (72.6-90.6%), NH4-N (62.9-85.3%) and TP (64.8-87.2%). A sharp decrease in TP purification and removal rates were observed in 2008 due to sharp decrease in influent TP concentration in 2008 compared to 2007. OTR values for VF(a), VF(b), HF bed and total system were observed as 21.7, 19.3, 4.8 and 12.3 g O-2 m(-2) d(-1) respectively. Average k value of hybrid CW system for BOD5, TN, NH4-N and TP during study period were 7.0 +/- 1.8, 7.4 +/- 3.3, 5.6 +/- 4.1 and 4.9 +/- 2.0 m yr(-1) respectively. Average concentration of TSS, TP, TN and NH4-N in the final effluent for all years were below the discharge limit value of: 150 mg L-1 for TSS; 8 mg L-1 for TP, 60 mg L-1 for TN and NH4-N. However, average BOD5 and COD concentrations could not meet the discharge limit value of 120 mg L-1 during 2007 and 2008. (C) 2013 Elsevier B. V. All rights reserved

“…There were significant differences in the microbial community structure related to sand-batch (Section 3.1.2). It is therefore suggested that that the disparities in SHC were primarily related to biological clogging as previously described [24,[34][35].…”

The formation of environmentally toxic acidic waste from mining activities is a world-wide problem. Neutralization of this waste can be accomplished by physicochemical and/or biological means. In this short-term study, synthetic acid mine drainage was added to sandfilled mesocosms containing silica-dominated (quartz) sand. Glucose was added as a carbon source for microbial iron and/or sulphate reduction. Replicates contained two separate batches of sand obtained from the same quarry site. The investigations used to assess and compare the chemical and biological functioning of the replicates included system hydraulic conductivity measurements, sand chemistry, effluent chemistry and bacterial community fingerprinting. Minor differences in composition of the sand, including the levels of available nutrients and micronutrients, resulted in major differences in measured parameters. 2 Significant differences in effluent chemistry were found in systems containing different batches of sand. It was demonstrated that the characteristics of the sand and the presence of acid mine drainage impacted the bacterial community structure and function. The importance of the physical substrate on the selection of functional microbial communities in systems remediating AMD should not be under-estimated. The physical substrate should be carefully selected and it may be prudent to include small-scale comparative studies in each particular setting prior to full-scale implementation.
