Biowater Technology's CFIC® Biofilm Process is Highly Suitable for Polar Bear Weather Conditions

TØNSBERG, Norway, November 19, 2012 /PRNewswire/ --

Cold weather has a significant impact on wastewater treatment efficiencies. Removing contaminants like BOD, TSS and other nutrients from wastewater is necessary no matter the weather conditions. Biowater Technology's Continuous Flow Intermittent Cleaning (CFIC®)   process provides an added benefit in extremely cold weather conditions because of its robust biofilm. This technology was developed in Norway and has significant benefits over traditional wastewater treatment processes like Activated Sludge, MBR, SBR, and Lagoon processes.

Climate and temperature change affect treatment system performance. As wastewater temperatures drop in winter (Polar Bear weather), and during spring snow melt, bacterial activity decreases, thus treatment is impacted. Problems typically include mixed liquor washout conditions and a reduction in treatment capacity.

"Our CFIC® technology has a major advantage in cold weather over suspended growth systems in that bacterial population is maintained in the treatment vessel on carriers that provided increased protected surface area for growth and that carries an extremely high sludge age; therefore, the biofilm is not susceptible to washout like suspended growth processes." says Jon Siljudalen, CTO at Biowater Technology, Norway. "We have experienced promising results down to 4 degrees °C (39°F) for nitrification using biofilm technology.

Biowater's CFIC® process is a packed bed system and provides the advantage of a much higher dissolved oxygen transport into the biofilm when compared to biofilm systems like trickling filters and moving bed biofilm reactors (MBBR).  Biowater's CFIC® technology reduces energy consumption especially when compared to MBBR and AS plants by 30% and greater.

The CFIC® process acts as a filter and captures solids, making the secondary clarification footprint smaller and treatment more effective than does suspended growth and other biofilm processes.  The CFIC® process also enhances filtration and separation technologies creating higher quality effluent suitable for reuse.
