Co-epuration of winery and pesticides effluents, activated sludge with tertiary nanofiltration, two new technologies for pesticides effluents treatment

Abstract

Wine-related activities produce significant volumes of wastewater characterized by high concentrations in organic matter. The term of pesticides effluents defines the water coming from the emptying and the rinsing of the equipment used to pulverize the phytosanitary products on the vines. Pesticide pollution of surface waters from vineyards applications represents a considerable hazard for the aquatic environment. The nature of these wastes is very variable, indeed more than 150 active molecules can be employed. So, the main characteristic of these effluents is their toxicity towards the environment. In this study, an approach was developed to estimate the possibility of developing two biological wastewater treatment process for pesticides effluents treatment. The first one is particulary designed for small vineyard and is a co-epuration process combining winery wastewater treatment with pesticides effluents treatment. The second one is an activated sludge with tertiary nanofiltration and is particularly suited for large vineyards or regroupings of wine growers.

Treatment of winery wastewater by physicochemical, biological and advanced processes: A review

“…This is due to the fact that the residual COD is generally higher than the limits stated in this Directive, as shown in Figure 3 (b) (i.e. ranges from 175 to 4200 mg L -1 , with an exception of the MBR, CAS, air micro-bubble reactor and BSF where their average residual COD were approximately equal to 75 mg L -1 [8], 50 mg L -1 [46], 82 mg L -1 [37] and 46 mg L -1 [43], respectively).…”

Food‐Processing Wastes

“…An approach was developed to estimate the possibility of developing two biological wastewater treatment processes for treatment of pesticides effluents at wineries (Massot et al 2010). One approach was developed for small vineyards, and one approach was developed for large vineyards.…”
