Biological Wastewater Treatment: A Potential Solution to Wineries’ Water Shortage

Many in the Australian wine community is experiencing the after-effects of the extended winter drought. With the effects of the drought, vineyards are left dry, resulting in a reduced but sweeter yield. Reuters Jonathan Barrett claims this could lead to a corker of a vintage after his investigations.

A lack of rain for a season leads to the lack of irrigation water supply and ultimately, can impact vine fruit yield. This chain of events can cost grape growers, winemakers and sellers in the long run.

Agricultural and industrial sectors are being called to improve water efficiency and wastewater management to resolve water supply shortage and protect the environment.

Improve water efficiency across all operations

Here are the common operations requiring large volumes of water allocation:

Cleaning and Sanitising Facilities – the general activities that use water such as washing floors, walls and ceiling do not take up a lot of water, but it can be improved by using reused water instead of fresh water.

Cleaning and Sanitising Equipment – maintaining the equipment such as tanks, presses and crushers require heavy consumption of water because the equipment comes into contact with the actual product. Instead of flushing the used water down the drain, it can be collected and reused to wash the facilities instead.

Cleaning and Sanitising Barrels – water used to clean and sanitise barrels can also be used to clean facilities as well.

Barrel Hydration – water used to hydrate barrels are clean enough to be used to wash facilities, equipment and bottles for packaging.

Bottling – water used to clean bottles can be reused to wash equipment and facilities.

Solids Management – placing strainers and nets to keep solids from going down the drain will prevent septic tanks and sewage systems from clogging and improve the wastewater treatment efficiency.

Biological Wastewater Treatment

Using untreated wastewater to irrigate vineyards can contaminate the land, water resources and crops, whilst causing odour and EPA compliance issues, unless greatly diluted with a secondary fresh water source.

Biological wastewater treatment converts wastewater into clean water using a natural, biological oxidation process. ultraBiox™ systems from Waterform Technologies are designed, manufactured and installed either with aerobic or anaerobic treatment processes. These can be a tank based plant, or a lagoon based solution. Different levels of treatment can be designed based on discharge quality criteria, such a different target levels of BOD/COD and nutrients. Utilizing technologies such as Moving Bed Bio Film reactors, Upflow Sludge Blanket Reactors, Surface Aspirators, and more, Waterform has the right biological treatment solution for your wastewater problem. DAF (dissolved air flotation) units and screening can also be combined with a biological stage to ensure treatment efficiency and effectiveness is maximised.

This treated wastewater is a valuable resource and using recycled wastewater to safely irrigate vineyards is a sustainable solution that wineries can adapt to resolve water shortage and contribute to saving the environment. Membrane treatment can be added to further enhance the quality of the treated water, for higher value reuse such as in condensers, cooling towers, boilers, equipment wash-down and more.
