INCREASING PROJECTS' SUSTAINABILITY
CLEAN WATER AND SANITATION
Ensure access to water and sanitation for all
Over 2,000 million people in the world live without access to a basic drinking water service, and 3,6 billionhave no access to a basic sanitation service, resulting in avoidable deaths, chronic disease, fewer hours of education and low productivity.
ACCIONA has positioned itself as a key player in the water treatment sector. Its innovative management seeks to resolve the challenges with respect to the shortage of water resources.
Take urgent action to combat climate change and its impacts
The generation and use of energy accounts for 35 % of total greenhouse gas emissions in the world. This activity is the largest contributor to global warming. Investment in renewable energy, energy efficiency and other low-carbon technologies will continue to be essential to meet the emerging needs of humanity and to minimize their negative impact on the environment.
ACCIONA considers the fight against climate change and its effects to be a strategic priority. The company works to mitigate greenhouse gas emissions in order to contribute to the progress of society and respond to the main challenges of sustainable development in the areas of infrastructure, water and energy, leading the transition to a low-carbon economy.
The technology removes high nitrogen loads, using special bacteria. It is a versatile process as it can be adapted to varying inlet water conditions.
The application of the NIPARMOX® process provides additional capacity in the overall removal of nitrogen in a WWTP, reducing by 25% the aeration needs in the biological reactor, with the impact this has on the energy consumed by the treatment plant.
In addition, it completely eliminates the need to provide external organic matter and reduces energy consumption due to recirculation.
The process consists of a partial ammonium nitrification, where approximately 50% of the ammonium entering the process is oxidized, and an autotrophic denitrification with anammox bacteria, where the nitrite produced with the remaining ammonium is reduced to nitrogen gas.
Both ammonium oxidation and anammox denitrification are carried out simultaneously in a biofilm supported on mobile fillers, and in the sludge in suspension.
The process is controlled by an advanced algorithm that regulates the ammonium oxidation process based on ammonium and nitrate measurements at different points in the process.
The NIPARMOX® technologies, patented and validated in a series of R&D projects, are used in the Kütahya WWTP in Turkey.
