” Norway’s most beautiful wastewater treatment<br />
plant in Norway’s coolest city”
The whole chemical handling system was<br />
housed in the existing basin hall.<br />
Actiflo® - from 0-100<br />
in 10 minutes!<br />
Greater capacity -<br />
same floor footprint!<br />
<strong>Solumstrand</strong> <strong>Wastewater</strong> <strong>Treatment</strong> <strong>Plant</strong> was built<br />
in 1991 with a capacity of 3.000 m 3 /h using primary<br />
calcium precipitation and seawater. A subsequent<br />
requirement for secondary treatment plus the need to<br />
increase the capacity to compensate for the closing of<br />
the Muusøya <strong>Treatment</strong> <strong>Plant</strong>, led to a major renewal<br />
and expansion of the plant in 2011. The new design<br />
capacity is 4.000 m 3 /h which includes both chemical<br />
precipitation and biological treatment.<br />
DESIGN<br />
Kaldnes MBBR Actiflo®<br />
Four parallel lines with<br />
2 Kaldnes MBBR in series followed by<br />
two Actiflo® units built on site<br />
Reactor volume/line 2 x 390 m 3 -<br />
Reactor Lamella surface/line - 2 x 26 m 2<br />
Fill-level biomedia 59 % -<br />
SALR (10°C) 11,5 g BOF 5<br />
/m 2 *d -<br />
Kaldnes biomedia Kaldnes K3 -<br />
Air capacity 18.400 Nm 3 /t -<br />
Solution<br />
Four of the existing 6 sedimentation basins were<br />
converted to Kaldnes MBBR reactors while the<br />
remaining two were rebuilt as dual-flow Actiflo®’s,<br />
each with a capacity of 2.750 m 3 /h. This released more<br />
space in the basins that could be used for storing<br />
chemicals and dosage equipment. This combination of<br />
processes increased the capacity and transformed the<br />
treatment process without having to extend the plant<br />
area.<br />

Task:<br />
To design a treatment plant with expansion possibilities that<br />
can cater for large, seasonal variations in waste-water and<br />
organic loads.<br />
Solution:<br />
Combine two well-proven technologies - the compact<br />
Kaldnes MBBR process for removing organic waste and<br />
Actiflo® for chemical precipitation and solids separation.<br />

renseanlegg<br />
Oppstart<br />
2011<br />
Kunde<br />
Drammen kommune<br />
Konsulent: Norconsult<br />
Utfordring<br />
Å designe et renseanlegg med planlagt fremtidig utvidelse og store sesongvariasjoner i vannmengde og organisk<br />
belastning.<br />
Løsning<br />
Kombinere to vel prøvede teknologier. Den kompakte Kaldnes MBBR prosessen for fjerning av organisk stoff<br />
og Actiflo ® for kjemisk felling og partikkel separasjon.<br />
