Tertiary treatment using ultrafiltration

ACCIONA has implemented an ultrafiltration system in its Wastewater Treatment Plant (WWTP) at Moratalla (Murcia province, southern Spain) that improves the tertiary treatment system in the plant. This ensures compliance with the new limits proposed by the European Union for treated water re-use, and a part of this water can be used for irrigating crops.

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.

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
