“…This variation is likely due to the samples being taken on different days. These concentrations are in agreement with data presented by Malandra et al (2003) and Petruciolli et al (2001). Relative to the dominant organic components, these levels are insignificant on the basis of concentration.…”

“…This increase is consistent with the fact that potassium is a major inorganic constituent of grapes, and hence grape juice and wine (Sheridan, 2003). The potassium concentration range is within the range of values found by others (Malandra et al, 2003;Sheridan et al, 2005).…”

“…As stated previously, these acids are not significant in terms of their contribution to the effluent COD, but they are significant environmentally because of their malodour. These findings are similar to the levels found in the effluent of Cellar 1 and also by Malandra et al (2003).…”

“…This measurement is discussed in Methods. The COD of the effluent peaked in mid-March (which is mid-harvest) and decreased for the rest of the year; this is in common with the findings of others (Malandra et al, 2003;Sheridan, 2003;Colin et al, 2005). The maximum concentration found (3800 mg/L) is also in the expected range for a cellar of this size (Sheridan, 2003).…”

Winery effluent is known to have a high chemical oxygen demand (COD) and a low pH. In this study, we extensively analysed effluent from two cellars and studied the temporal changes over the duration of a harvest and the duration of a year. We found that ethanol contributes approximately 85% to 90% of the COD of raw winery effluent, with acetic acid being the next significant contributor. The pH showed some dependence on the concentration of acetic acid. The concentration of sodium in the effluent is strongly dependent on the cleaning regime in place at the cellar, and the concentration of potassium has been shown to be linked to the spillage of juice, wine or lees. The data and correlations presented here could allow for an artificial effluent to be prepared easily for research purposes.

Rotating biological contactors (RBCs) have been used as an efficient fixed film method of treating wastewater due to its advantages such as low energy and land requirements or simplicity of operation. In this article, we firstly describe the operation, benefits and drawbacks, hydrodynamics and typical applications of these bioreactors, and then review the main factors affecting their performance. Some aspects about RBC design and scale‐up, the main operational problems and their resolution are presented. The comparison of the performance of RBCs with other wastewater treatment systems as well as costs considerations and prospects are also discussed.

Turning wine (waste) into water: Toward technological advances in the use of constructed wetlands for winery effluent treatment

The research presented in this article describes an investigation into the use of vegetated submerged reedbeds (VSR) as a practicable alternative for effluent treatment for small-scale wine producers. In this study, we found that the hydraulic processes occurring within the VSR display significantly nonideal behavior. If the feed to the VSR was located on the surface the dead volume accounted for approximately 25% of the nonideal behavior of the system and bypass accounted for a further 6%. A preferential flow pattern was found within the VSR with the greatest flow occurring closest the surface and in the center, and the least at the sidewalls. We propose that the flow profile can be conceptualized as being hull shaped and found that this profile was the same for irregularly shaped gravel and for spherically shaped gelatinous beads. We, therefore, hypothesize that it is not dependent on the geometry of the VSR or the packing medium.
