About SIGMADAF
SIGMADAF − based in Spain and operating worldwide − designs, manufactures and installs membrane bioreactors for industrial effluent treatment and water reuse. Our MBR systems are compact, self-contained and easy to operate. We also supply decentralized membrane bioreactors for installation and operation in remote locations.
MBR technology & applications
Proprietary MBR products and systems:
- MBR System: Biological Reactor + Membrane Filtration
- MBR Packaged Plant
- Decentralized STP
Our MBR bioreactors are equipped with ultrafiltration membranes that maximize their efficiency and performance for contaminant separation. Thanks to this technology, the biomass concentration inside the reactor is much higher than that of reactors with conventional clarifiers, being possible to reach between 6,000 and 12,000 mg/L.
The combination of the membranes and the activated sludge reactor has the following advantages:
• Higher performance in the elimination of organic matter.
• The quality of the water output is constant.
• Compact equipment that occupies a small footprint.
Our membrane bioreactors are delivered in a compact system and ready to operate upon arrival at the customer's facility.
Our MBR systems include KUBOTA brand ultrafiltration parallel flat membranes, which are vertically submerged in the aeration chamber, inside the mixed liquor.
In scenarios where there is a high nitrogen concentration and/or nitrates are generated above the discharge limits, a modified MBR system with an anoxic pre-chamber will be offered. This configuration allows for the simultaneous removal of COD and nitrogen by nitrification-denitrification.
