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(R))
[http://www.biowatertechnology.com/en/index.php?mod=pages&id=150 ] 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
[http://www.biowatertechnology.com/en/index.php?mod=pages&id=165 ]), 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(R) 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 degree(s)C (39degree(s)F) for
nitrification using biofilm technology.

Biowater’s CFIC(R) 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(R) technology
reduces energy consumption especially when compared to MBBR and AS plants by 30% and
greater.

The CFIC(R) 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(R) process also enhances filtration and separation
technologies creating higher quality effluent suitable for reuse.
