Membrane bioreactor for high-quality effluent and reliable biomass retention
The ALMA BIO MBR combines aerobic biological wastewater treatment with membrane filtration. Organic contaminants are biologically degraded in the aeration tank. A membrane filter box then reliably separates the treated water from biomass and fine suspended particles. This eliminates the need for a separate secondary clarifier.
Aerated Activated Sludge Tank
Microorganisms break down biologically available organic substances in wastewater. Fine-bubble aeration supplies the biomass with oxygen.
Filtration in the Membrane Box
The sludge-water mixture is filtered through submerged plate modules. Biomass and fine particles are reliably retained.
Low-Solids Discharge
Depending on the requirements, the filtrate can be discharged or sent for further treatment and water reuse.
Advantages of the ALMA BIO MBR
- Reliable Retention of Biomass and Fine Particles The membrane forms a defined physical barrier and reliably separates clear water from activated sludge.
- No separate secondary clarifier required Solid-liquid separation takes place in the membrane filter box and does not depend on the settability of the sludge.
- Compact System Configuration Biological treatment and membrane separation can be combined into a compact solution, even when space is limited.
- High biomass concentration possible Reliable biomass retention enables a high level of biological activity in the aeration tank.
- Modular, Scalable Treatment Capacity Nitrification, denitrification, and phosphate precipitation can be added depending on the required effluent parameters .
MBR or conventional secondary treatment?
Membrane bioreactor for stringent effluent requirements
An MBR is particularly useful when the system is designed for a low-solids effluent, a small footprint, or further water treatment.
Secondary Clarifier for Rugged Standard Applications
Conventional sedimentation can be cost-effective, provided there is sufficient space, the sludge settles well, and particularly low solids levels are not required.
The selection is made on a project-by-project basis
Key factors include wastewater volume, organic load, sludge settleability, available space, effluent quality, energy requirements, maintenance, and the potential for water reuse.
