BIO-CEL® MBR Laboratory Module for Pilot Installations

With a scaled-down version of its innovative MBR system BIO-CEL® (BIO-CEL® Lab), MICRODYN-NADIR is presenting a new module type at FILTECH in Wies­baden which allows a wide range of MBR-related processes and process variants to be investigated on a laboratory scale.

Membrane bioreactors (MBR) are the latest innovation of activated sludge systems for waste water treatment. In our BIO-CEL® Membrane Module, secondary clarifiers are replaced by a highly efficient and reliable membrane based bio-mass separation process requiring a much smaller footprint.

Thanks to an ultrafiltration membrane with unsurpassed separating capacity and flow performance, the BIO-CEL® Membrane Module offers an efficient, reliable, cost effective and future oriented solution with a significantly higher purification rate and a solid-free discharge.

The BIO-CEL® Lab has a membrane surface area of 0.35 m2 installed in a PVC frame with integrated crossflow aeration via a membrane diffuser. Connections for permeate drainage and air supply are already provided. The module can thus be installed and ready for use in a laboratory in the shortest possible time. The PES ultrafiltration membrane (type UP150) is identical to that of the full scale BIO-CEL® module, enabling qualitative statements to be made on experimental filtrate measurements.

BIO-CEL^®-Reference Brochure Marienhospital

The chemical industry is facing a multitude of economical and environmental challenges. Not only is it detrimental for a chemical plant’s continuous existence in today’s global environment to become more and more cost-effective, the environmental regulations are also becoming increasingly stringent. Hence, the MBR technology with its high quality effluent proves to be a good fit for the wastewater plants in the chemical industry. The MBR reference at the Marienhospital in Gelsenkirchen, Germany is a good example of a wastewater plant that is using MBR because of high effluent quality requirements.

In July 2011, the wastewater plant at Marienhospital in Gelsenkirchen, Germany was put into operation. It is the first European wastewater treatment plant that focuses on the elimination of micro pollutants as well as the purification of the waste water from the hospital. The plant was built in the context of anEU-project called “PILLS” (Pharmaceutical Input and Elimination from Local Sources) under the aegis of the Emschergenossenschaft.

The project´s goal is to eliminate micro pollutants in the sewage water on site, which especially incur in hospitals as residues from pharmaceuticals and radio-opaque substances.

About 75,000 patients are being treated by approximately 1,200 staff members at the Marienhospital per year. Thereby effluents amounting up to 200 m³/d incur. Until now, these effluents have been discharged into the nearby river “Schwarzbach” via the municipal canalization. This creek currently still serves as an open sewage water drain outlet but is targeted to be renatured and operated effluent-free in the course of the conversion. Amongst others, it will also absorb the purified water from the new clarification plant. This new wastewater treatment plant encompasses, besides a mechanical and biological clarification, a variety of treatment processes, such as an ultrafiltration with submerged modules (MBR technology), an ozonization as well as an activated carbon filtration.

For the Ultrafiltration, three submerged BC400 modules by MICRODYN-NADIR have been installed. In total these modules have a membrane area of 1,200 m² through which the biologically purified sewage water is being removed from the aeration tank. The ultrafiltration permeate, which is now free of particles and bacteria, will afterwards be led to an ozonization and an activated carbon filtration. Ozone, a strong oxidizer, provokes the cleavage of the micro pollutants in solution and converts them into nonhazardous substances. In addition, the micro pollutants are being absorbed by pulverized activated carbon, which is then removed from the water including these trace substances.
