Galdakao Hospital in the Basque Country (Spain) reduces waste management costs thanks to Veolia's EVALED® technology.

The new system will allow the hospital to reduce wastewater management costs, which are currently outsourced. Furthermore, with EVALED® technology, the facility will also comply with its own environmental policy, thanks to more sustainable management.

The Veolia Group's ambition is to become the benchmark for ecological transformation. Present on five continents with nearly 218,000 employees, the Group designs and provides practical, practical solutions for water, waste, and energy management that contribute to radically changing the world. Through its three complementary businesses, Veolia helps develop access to resources, preserve existing resources, and reuse them. In 2023, the Veolia Group provided drinking water to 113 million people and served 103 million with wastewater services, produced nearly 42 million megawatt-hours of energy, and treated 63 million tons of waste. Veolia Environnement (Paris Euronext: VIE) reported consolidated revenues of €45.351 billion in 2023. www.veolia.com

The Spanish subsidiary of Veolia Water Technologies recently signed an agreement with the Galdakao-Usansolo Hospital in Vizcaya to install an evaporator to reduce the volume of Type V chemical waste currently managed externally by up to 80%. This operation will allow the hospital to achieve similar savings in this budget item and, in addition to the obvious economic benefit, will enable the hospital to develop more sustainable management, reducing CO2 emissions from transportation and generating a high-quality distillate that can be reused for ancillary services within the hospital.

The offering is enhanced by the Hubgrade ESSENTIAL digital solution for remotely monitoring key operating parameters in real time, providing additional control that facilitates a rapid response from Veolia in the event of failures or other issues.

The 80% wastewater reduction will be achieved thanks to EVALED® evaporation technology, which effectively separates water from dissolved contaminants. Specifically, the equipment chosen by Galdakao Hospital is an EVALED® PC F model, featuring vacuum evaporation technology with a heat pump and forced circulation, which allows for effective low-temperature treatment of liquids with a high dissolved solids content, producing minimal scale and dirt.

Evaporation technology minimizes wastewater by generating two streams: a concentrate whose volume can generally be reduced by up to 5-10%, and a very high-quality distillate that can be reused (ZLD).

With this solution, Veolia guarantees treatment of up to 250 liters of wastewater per day, although the equipment has a treatment capacity of up to 700 liters per day to accommodate potential peaks or future increases.

This technological solution has also been successfully implemented at the Ramón y Cajal Hospital in Madrid, allowing the hospital to significantly reduce the volume of wastewater, previously outsourced, since its installation in 2017.

Companies are increasingly aware of the need to pursue a sustainable environmental policy and are seeking solutions that minimize the volume of waste produced.

The effectiveness of EVALED® evaporators in reducing wastewater volumes and producing high-quality distillate, along with lower disposal costs, have made this solution ideal for various sectors: mechanical, pharmaceutical, chemical, food, mining, etc.

In addition to reducing operating costs, evaporation technology provides another key advantage: the recovery of substances used in the production process, such as metals used in the surface treatment industry, active ingredients in the food industry, precious metals, and sodium sulfate.

The economic benefits of evaporation technology are therefore both direct, through the reduction of operating and disposal costs, and indirect, through the reuse of water and the recovery of production process byproducts.
