Understanding Wastewater Treatment Demands for Wineries

Wastewater treatment tankAlthough many people enjoy wine, only a few understand the process of wine production. The process generates quite much waste, with a large percentage being wastewater, which necessitates the use of highly efficient winery wastewater treatment systems. The wastewater is a product of the cleaning process of the machinery and equipment during the production process.

The amount of water, however, varies with the stage of production. The common stages that release wastewater are the harvesting, cellaring, and bottle cleaning.

Harvesting

This stage contributes to about half of the wastewater from the production process. The wastewater comes from the process of cleaning and pressing the grapes and cleaning any spillage. Also, this wastewater contains high amounts of contaminants.

Cellaring

The next process after cleaning and pressing the grapes is preparing the wine to mature, where the wine sits in a fermentation tank for a certain time until it reaches its maturation time. Various types of wine take different amounts of time to reach maturation. The wine further moves to the next stage of clarification before the bottling process. Separation of the sediments from the process follows through centrifugation, which generates liquid effluents and solid waste.

Bottling

In this stage, the wastewater is from the process of cleaning bottles and disinfecting the bottling equipment. Unlike the other prior stages, the bottling process does not produce much wastewater. The wastewater does not contain many contaminants, as well.

Regardless of the amount of waste from the production process, the water contains contaminants and require treatment before discharging. Some of the contaminants are biodegradable, while others require unique processes to eliminate the harmful contaminants. Therefore, it is crucial to have wastewater treatment systems that will treat water and minimise the volume.
