| Coca-Cola Beverages Hrvatska:
Redesign of wastewater treatment facility |
| March 2003 |
Situation
Coca-Cola Beverages Hrvatska (CCBH) of Croatia
has successfully redesigned its wastewater
treatment facility and drainage system to
a level beyond regulatory requirements and
in turn the company is saving money and reducing
the need to use drinking water on site.
Targets
For CCBH, environmentally responsible management
is top priority. In particular, wastewater
treatment is an integral part of the company's
environmental management efforts. CCBH's Wastewater
Policy makes the following statements:
 |
All existing factories
that let their wastewater out in the
city wastewater treatment system must
constantly meet the wastewater requirements
and quality standards that are in force
in the country. |
|
All existing factories
that let their wastewater out into natural
sources like rivers or lakes shall build
a system of wastewater treatment and
achieve a level of wastewater purity
that is supportive of the existence
of fish. |
Actions
To meet these targets, the company reconstructed
wastewater separation facilities and redesigned
and developed the wastewater treatment system.
From 1996 until 1999, CCBH reconstructed drainage
systems in its Zagreb and Solin plants by
separating technological wastewater treatment
from the system of rainwater drainage and
sanitary wastewater. After that, a new wastewater
treatment facility was developed in both locations.
The system follows a three-step process:
|
Step one in the technological
wastewater treatment is removal of any
mechanical impurities through fine metal
sieve. |
|
Step two includes chemical
treatment of water in an equalisation
tank. Here wastewater is neutralised
by bringing pH value within the range
acceptable for biological treatment. |
|
Step three includes
biological treatment followed by aerobic
dissolution.
In order to reduce the total quantity
of wastewater that is disposed of an
80 m3 reservoir was built for collection
of a purified wastewater on site - to
be used for secondary purposes such
as watering lawn areas. Fish tanks were
also built. |
Results
Wastewater quality control is carried out
on a regular basis internally as well as by
an independent institution. Results from the
independent evaluations show treated water
quality levels to positvely exceed the legally
required levels of purity. The sludge that
is the side product of wastewater
treatment was shown to meet the requirements
for use on farming land.
Reconstruction of drainage system and development
of wastewater treatment facility have produced
the following WIN-WIN benefits:
|
Wastewater Policy requirements
have been met - wastewater quality has
been raised to the level of supporting
the existence of fish |
|
Considerable savings
were made through the reduction of water
pollution fees. |
|
Treated wastewater is
partly used for secondary purposes (saving
up to 60m3 of drinking water daily during
summer). |
Although these efforts have met with considerable
success to date, CCBH believes there is always
room for improvement. In the last four years
CCBH has managed to constantly reduce water
consumption through technological and organisation
changes. The company is continually striving
to reduce its water use levels at source and
increase the re-use of treated wastewater.
