Agri-food wastewater has a very high treatment cost, yet it contains valuable compounds that can be recovered and used.

The effects of climate change and increasing water scarcity and pollution threaten the availability and quality of water as a resource for food production.

Water will become the main limiting factor for global food production in the coming years. 70% of global freshwater withdrawals are already used for food production, especially for agricultural raw materials.

The agri-food industry is a major user of water either as an ingredient or as an indispensable resource in the production stages. This includes the cleaning and disinfection operations that are essential to guarantee food safety.

Recovering water and other resources such as proteins, lipids, sugars, fibres, nutrients, etc. by means of new technologies saves production costs and reduces environmental levies and duties.

At AINIA we give you value

  • Processes for recovering water from raw materials, and proteins, lipids, fibres, dyes, antioxidants, etc. from agri-food liquid streams.
  • Processes for reusing industrial agri-food water in the industry itself or in agricultural crops for fertigation. Also for other uses, but always with the highest hygienic guarantees.

Wastewater resource recovery

We develop solutions for water reclamation and recycling including conceptual design for its integration in the process line, piloting and technical-economic evaluation and assessment of the product water’s hygienic-sanitary conditions.

We use membrane technologies such as micro-, nano- and ultrafiltration, electrodialysis, extraction, precipitation, purification, etc. that allow the recovery of important compounds such as carbohydrates, lipids and proteins. We also develop nutrient recovery processes using microalgae or aquatic plants.
