Na ICP Ljubljana potekajo raziskave 
alternativnih tehnik ~i{~enja papirni{kih 
odpadnih vod. V okviru projekta 
evropskega projekta CORNET (ERA-
net projekti) – Albaqua raziskujemo 
alternativno tehniko biolo{kega ~i{~enja 
papirni{ke odpadne vode z uporabo alg. 
Gre za nadgradnjo konvencionalnega 
aerobnega ~i{~enja s simbiotsko algno-
bakterijsko biomaso. Zaradi specifi~nih 
karakteristik mikroalg in u~inkovite 
kombinacije z bakterijami pri~akujemo 
bolj{i ekonomski in ekolo{ki efekt ~i{~enja. 
Kisik, ki ga pri svojem metabolizmu 
proizvajajo mikroalge, uporabljajo 
heterotrofne bakterije za oksidacijo 
organskih ne~isto~, pri ~emer pa nastaja 
CO

, ki ga potrebujejo alge za svojo rast. 
Zaradi omenjenih procesov lahko ob 
enakem efektu ~i{~enja vode pri~akujemo 
znatno znižanje energetskih stro{kov.
V Papirnici Gori~ane smo v sodelovanju 
s partnerji iz projekta Albaqua postavili 
pilotni bioreaktor s kapaciteto 500 
litrov. V poskusih ~i{~enja razli~no 
obremenjenih papirni{kih odpadnih 
vod posku{amo dolo~iti optimalne 
tehnolo{ke pogoje delovanja, na primer 
osvetljenost, temperaturo, pH, prevodnost 
in raztopljeni kisik, ter opredeliti efekt 
~i{~enja. Pilotni poskus bo pokazal, 
ali je omenjena tehnika primerljiva ali 
u~inkovitej{a od konvencionalnih na~inov 
biolo{ke obdelave.

PILOTNA BIOLOŠKA
VODO-^ISTILNA NAPRAVA

Some novel water treatment techniques are currently being tested at the Pulp and Paper Institute. Within the European 
ERAnet project (CORNET – ALBAQUA) a research is running on utilisation of alternative biological water treatment using algae. 
Conventional aerobic treatment may be thus upgraded by using symbiotic algae-bacterial biomass. Due to specific properties 
of micro-algae and efficient combination with bacteria improved economical and ecological results of effluent treatment are 
expected. Oxygen produced by micro-algae during photosynthesis may be used by heterotrophic bacteria in order to oxidise 
organic imputities by which carbon dioxide is produced. The latter is needed for algae growth. Thus, with the same cleaning 
effect a significant reduction of operation costs is expected. 
A pilot bioreactor with capacity of 500 l was constructed at the Paper mill Gori~ane in collaboration with ALBAQUA project 
partners. During its operation differently loaded effluents have been treated and optimal techological conditions determined as 
for example light intensity, temperature, pH, conductivity and dissolved oxygen. Cleaning efficiency dependant on all relevant 
parameters has been constantly monitored. 
According to the results of the pilot tests it will become clear whether this novel technique is similarly or more efficient than 
conventional biological treatment.
