Our FAQ answers frequently asked questions about industrial wastewater treatment, REUT, and Serre-Filtrante® to guide you in your projects.
Effluent variability is managed at several levels:
- Separation of solid and liquid phases by a screen.
- Dilution, homogenization, and aeration of effluent in a buffer tank.
- Dilution and homogenization make it possible to reduce the concentration and/or neutralize the cleaning products you use and render them harmless to the system.
- Ventilationaeration helps prevent fermentation, reduces COD, and thus facilitates decontamination.
- Adaptability of the bacterial committee to different pollutants.
- Capacity forhyper-accumulation of pollutants by plants.
- Closed-loop operation closed circuit to increase pollution control capacity.
- Water quality testing using an analysis probe.
If you have any doubts about the acceptability of a product you are using, contact us.
We use semi-aquatic, endemic to the Southeast region, with hyper-accumulating properties.
These characteristics allow us to develop them in water and clean up effluents by capturing large quantities of pollutants.
Juncus effusus: commonly known as common rush, is a perennial plant belonging to the Juncaceae family.
Environment: It is a plant of wetlands and is commonly found in marshes, swamps, and along the banks of rivers and ponds.
Morphology: The plant has cylindrical stems that can grow up to 1.5 m tall and are topped with a cluster of small greenish-brown flowers.
Iris versicolor: Iris versicolor is a species of flowering plant in the Iridaceae family.
Habitat: It is a perennial plant native to the wetlands of North America, particularly swamps, marshes, and the edges of ponds and streams.
Morphology: The plant has long, narrow leaves that can grow up to 3 feet tall, and it produces striking blue or purple flowers with three large petals and three smaller sepals.
Abilities: Iris versicolor is a popular ornamental plant, but it is also used in phytoremediation projects due to its ability to absorb heavy metals and other contaminants from soil and water. In addition to its environmental benefits, Iris versicolor is also used in traditional medicine to treat various ailments, including skin problems, headaches, and inflammation.
This flower has been shown to effectively absorb organic compounds, heavy metals, and pesticides in water.
This makes it a popular choice for phytoremediation projects, particularly in wetland environments.
The regulations applicable to a given operation depend on its production capacity :
- < 500 hL : Loi sur l’eau, code rural et règlement sanitaire départemental
- From 500 to 20,000 hL : ICPE subject to declaration. Decree of March 15, 1999
- > 20,000 hL : ICPE subject to authorization. Decree of May 3, 2000
(ICPE: Classified facilities for environmental protection)
Current declaration and authorization decrees set out the measures to be taken for measuring water flows and encourage manufacturers to reduce their consumption.
In any case, every facility must implement a system for managing its effluents.

Cleaning products that you can use, such as hydrogen peroxide, soda, peracetic acid, etc., will not cause any problems for the system and even have purifying properties.
When used in large quantities, plants can lose their vitality.
On the other hand, there is good acceptance by bacterial committees.
Homogenization in the upstream buffer tank largely compensates for this.
If you use biocides, it is best to notify us so that we can conduct internal tests.
In order to keep the biological elements alive, a sensor alerts us when the level in the retention tank is low. The system then switches to a closed circuit between the tank and the filtration modules without releasing the treated water.
This allows the system to be irrigated in a loop until production resumes.
Yes, they are carried out by the Azuvia team on a flat-rate basis.
This involves cleaning the filtration modules with plant trimmings (leaves and roots) and cleaning the growing media. These actions are carried out at least twice a year, and more often if necessary.
This solution is eligible for a subsidy from the water agency of between 10% and 50%.
The amount is determined based on the actual environmental impact on the receiving environment.
Your water supply can come from several sources: public network, well, surface water collection or rainwater storage.
In a context of increasing water stress and increasingly strict regulations, it is essential to know precisely where your water comes from and the pressure exerted on local resources.
Theidentification of the source is a first step towards more sustainable management. But to secure your business, it is crucial to go further.
The reuse of treated water (REUSE) allows you to reduce your dependence on natural resources, preserve authorized volumes during periods of restriction (e.g., drought) and maintain continuity of your production.
At Azuvia, we help you transform your effluents into a controlled resource , tailored to your needs and respectful of the environment.
To assess your water consumption in relation to wine production, we generally measure the amount of water used per liter of wine produced. Here is an indicative scale:
- 0.5 to 2 L of water/L of wine : Small consumer
- 3 to 5 L of water/L of wine : Average consumer
- 5 to 10 L of water/L of wine : Heavy consumer
Why is this important?
This data allows you to assess your environmental performance and identify ways to reduce water consumption.
Reducing your water consumption is a strategic issue, both economically and environmentally, as well as in terms of regulations. Here are some concrete best practices to implement in your operation:
– Reusing water (REUSE)
Treating and reusing your wastewater allows you to significantly reduce your dependence on natural resources and secure your business, even during periods of drought.
– Optimize your facilities
- Smooth surfaces : make cleaning easier and reduce the amount of cleaning required.
- Using a water meter : to accurately track your consumption and detect waste.
- Opt for one large tank rather than several small ones: better management of volumes and water cycles.
- Automate processes: Automating washing and circuits allows for more precise control of the volumes used, with better efficiency.
- Controlling pressure and temperature: Usehot water under pressure often reduces the volume needed while improving cleaning efficiency.
- Maximize every water flow: Reusing the same water for several stages of the process (pre-washing, cleaning, etc.) can reduce consumption by a factor of 2 to 3.
Every liter saved is a step toward more efficient, more resilient, and more sustainable production.
– Insoluble particles, more or less visible: plant debris (grape skins, pulp, seeds, etc.), filtration earth, tartar, yeast, microorganisms, and other suspended matter
– Soluble substances, invisible to the naked eye: sugars, organic acids, alcohol, esters, polyphenols, glycerol, proteins, etc.
It is their organic load that is high. Plant debris, microorganisms, and most soluble substances are organic. The load is assessed using two indicators:
– COD indicates the volume of oxygen that would be required to break down all the organic matter present in the effluent.
– BOD represents the amount of oxygen that would be used by microorganisms to utilize this organic matter.
Wine effluent contains 10 to 30 times more organic matter than domestic effluent.
It is the high organic matter content of wine effluents that makes them potentially polluting.
They can serve as food for other microorganisms present in the soil or water. These microorganisms will break down organic matter to make it unpalatable.
To do this, they use oxygen, among other things. Thus, in an environment such as water, the use of effluents by microorganisms leads to oxygen depletion.
Less oxygen causes discomfort for other aerobic organisms present in the water, to the point of causing them to suffocate.
For soil, it is different. When spread on the ground, effluents will generate odors linked to the decomposition of their organic matter.
In the event of proven serious pollution, the classified facilities inspectorate and the water police may issue fines; the National Office for Water and Aquatic Environments may also intervene if the pollution affects a watercourse.
The current gap between needs and resources is widening. These constraints on water resources are exacerbated by climate change. We anticipate more frequent droughts and lower river levels. This could lead to localized conflicts over water use and a reduction in the purification capacity of rivers, thereby increasing the risk of deterioration in water quality.
Choosing a solution that allows for reuse is therefore not insignificant. The filter greenhouse allows you to implement an alternative to drawing on conventional water resources, which are now severely limited.
Azuvia has already installed its filter greenhouse on several estates. Here, you will find examples such as Bastide de Blacailloux and Domaine des Bruyères.
