What’s the difference between reusing and recycling wastewater? <\/strong><\/h1>\n\n\n\n

In water-intensive industrial sectors such as food processing, chemicals and pharmaceuticals, wastewater treatment approaches are moving towards a circular logic<\/strong>. To limit withdrawals, secure production or anticipate shortages, more and more sites are seeking to recover their wastewater. But the technical, regulatory and environmental approaches to water reuse and recycling differ. Knowing how to distinguish between the two is essential if you are to adopt a water management strategy tailored to your objectives<\/strong>. Ovive explains how to make the distinction, and how to make the right choice! <\/p>\n\n\n<\/div><\/div>\n\n

Wastewater recycling: a closed loop<\/strong><\/h2>\n\n

Wastewater recycling means recovering the water used in an industrial process, treating it on site, then reinjecting it into the same circuit<\/strong>, often for the same purpose<\/strong>. This is a closed loop, controlled internally, which limits waste and reduces dependence on external resources. <\/p>\n\n

On a production site, this may involve cooling water, cleaning water or condensate recovered from thermal installations. This industrial water is then <\/strong>treated<\/strong><\/a> to a standard compatible with immediate reuse, without risk to either equipment or production. <\/p>\n\n

Recycling offers a number of advantages: it cuts supply costs<\/strong>, reduces waste volumes<\/strong>, and secures production <\/strong>in the event of local restrictions. It is also part of an environmental performance logic, which is valued in CSR initiatives. <\/p>\n\n

Wastewater reuse: a regulated change of use<\/strong><\/h2>\n\n

Unlike recycling wastewater reuse<\/strong><\/a> (REUT) refers to an approach whereby<\/strong> treated water<\/strong> is used for a purpose other than<\/strong> that for which it was collected, and sometimes outside its original site. This can involve industrial applications such as road cleaning or boiler feed, as well as urban or agricultural uses. <\/p>\n\n

Reuse is, however, strictly<\/strong> regulated<\/strong>. Regulations, and in particular the decree of March 10, 2020 and the two orders of 2024, define quality standards according to the intended use, as well as requirements in terms of treatment, monitoring, traceability and prefectoral authorizations. <\/p>\n\n

Treatment technologies tailored to each strategy<\/strong><\/h3>\n\n

The distinction between wastewater reuse and recycling is also based on the levels of treatment required<\/strong>: <\/p>\n\n
