WASTE WATER SYSTEM OF ABIDJAN
The waste water system of the City of Abidjan, Ivory Coast
receives both industrial and municipal wastes. Grease, hydrocarbons
and very high pollutional levels have been an ongoing challenge to the
operation of the treatment plant and to environmental protection. The
initial problem included the removal of a grease cap of 70 cm (28 in.)
in the Koumassi pretreatment plant. The basin was clogged with grease
and had been taken off line. The grease cap had been there so long that
plants had taken root (see before photo below).

Treatment Program
The Bacta-Pur® XLG was preactivated and continuously to the basin
to ensure a continuous presence of the microorganisms required to biodegrade
grease, sludge and to enhance reduction of COD & BOD.
AFTER
45 days: Grease biodigested |
Results
The first forty-five days of treatment resulted in removal of the grease
cap with simultaneous improvement in water quality (table and photos
below). Whereas the randomly occurring bacteria, in the waste water,
were unable to digest the grease, use of Bacta-Pur® XLG rapidly
eliminated the grease while dramatically improving water quality.
