Description

Biological process intensification has emerged as a promising strategy to upgrade existing wastewater treatment infrastructures, addressing challenges of urbanization and stringent environmental regulations.

MABR's unique feature is its dense gas-permeable membrane, serving as both a biofilm carrier and direct oxygen source for nitrifying biomass. This design enables aerobic conditions within the biofilm, facilitating Simultaneous Nitrification Denitrification (SND) and offering an efficient, compact solution for nitrogen removal.

The VA SYD Sjölunda wastewater treatment plant in Malmö, Sweden, has a treatment capacity of 379,000 PE and treats a daily flow of 112,000 m3/d. Recently, MABR technology has been implemented to increase nitrification capacity by 500 kg NH4-N/d. This paper presents an overview of the project, focusing on four key aspects:

1. Model-aided design.
2. Rapid installation completed in two weeks, minimizing operational disruption and costs.
3. Quick attainment of high nitrification performance
4. Enhanced total nitrogen removal, improving effluent quality and potentially reducing the need for external carbon sources.

These preliminary results demonstrate MABR's potential as an effective solution for upgrading wastewater treatment facilities, offering improved nutrient removal capabilities and operational flexibility without extensive infrastructure expansion. Long-term performance data will provide further insights into the technology's sustained impact.
