Tertiary treatment using ultrafiltration
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 tertiary treatment is done through an ultrafiltration process. The heart of the system consists of ultrafiltration membranes located in a frame, with each frame containing 16 modules of membranes.
Ultrafiltration technology leads to high-quality effluent and ensures compliance with required standards under greater guarantees, as it is less affected than other treatments by any modifications to the surrounding environment: changes in the process, industrial discharges, heavy rainfall…
This new ultrafiltration (UF) system complements existing tertiary treatments in the WWTP and helps to minimize flows, which can leave the plant without tertiary treatment at times of heavy rain.
ACCIONA has operated the Moratalla Wastewater Treatment Plant since late 2019. The facility has a daily capacity of 4,500 m3 and provides a service to a population equivalent of 50,000 inhabitants.
- Type of contract: Operation & Maintenance
- Location: Moratalla, Murcia, Spain
- Capacity: 4,500 m3/day
- Equivalent population: 50,000
The benefits of re-use
Re-use is a highly useful resource to address the challenges posed by water management over the next few decades, such as scarcity or drought.
- It means that previously-used water can be taken advantage of
- It can generate additional water resources to conventional ones
- It helps to alleviate pressure on available water resources
- It helps to reduce the pollutant load
- It helps to protect the environment and the health of people and animals
