Volumetric Loading

The Aerobic Upflow Sludge Blanket (AUSB) Process is a new biological wastewater treatment process applying the concept of the self-immobilization to aerobic activated sludge. This report discussed the experimental results for municipal sewage treatment using the pilot AUSB apparatus. The sludge produced in the AUSB process formed granules (diameter: 2 - 8 mm), showing excellent settleability. Under the condition of 1.57 kg/m3 day of BOD volumetric loading in winter, the following quality was obtained for the treated water : 20 mg/ℓ of BOD and 9.6 mg/ℓ of SS. The MLSS in the AUSB reactor was maintained at 8200 mg/ℓ.

Phytosanitary Products

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 particulary suited for large vineyards or regroupings of wine growers.

The Cost

The possibility of withdrawing alcohol wastewater from thermal treatment to a sewage treatment plant was considered in this article. These measures can reduce the cost of fuel used for thermal treatment, as well as improve the quality of the biological wastewater treatment process
