Stabilisasi Lumpur Kering Dari Limbah Cair Pengolahan Kulit Dengan Abu Layang
ABSTRACT: The experiment of
solidification of dry sludge of liquid waste of leather treatment are
containing chrome (Cr) by using fly ash has been done. The experiment objective are immobilize Cr in
the solid waste by using pozzoland cement was made of fly ash in order to
stable in the repository. The experiment
were carried out by solidification of solid waste are containing total chrome
of 1480.5 mg/kg sum of 2 – 10 weight % of (water + pozzoland cement) by using
pozzoland cement was made from the mixture of fly ash and calcite were burned
at 1000oC temperature for 2 hours.
The characterization of the solid composite of stabilization result
consist of the compressive strength test
and the leaching test by American Nuclear Society (ANS-16.1) method. The experiment result were shown that
pozzoland cement can binding solid waste
sum of 10 weight % of (water + pozzoland cement) became the composite of waste
concrete with the compressive strength of 577 ton/m2 and the chrome leaching
test for 14 days of 0.059 mg/l. The
composite of waste concrete according to Bapedal rule for solidification of
toxic waste with minimum compressive strength of 10 ton/m2 and
maximum leached chrome of 5 mg/L.
