Abstract: The improvement of
laundry activity brought
a negative effect
on the environment
because laundry wastewater have
a high content
pollutants such as
phosphate, surfactants, mineral, nitrogen, COD and other components,
so the treatment is needed before being discharged into terristorial water.
Laundry wastewater treatment
has been conducted
by membrane technology.
Preparation of cellulose diacetate
membranes with ultrafiltration process had be done by
phase inversion using
dimethylformamide (DMF) as
a solvent. The
filtration experiment showed
that the
highest membrane flux
was 77,408 L/m2.h at
TMP 3 bar.
While the lowest flux
at TMP 1
bar was 55.649
L/m2.h. Rejection of
membrane ultrafiltration for parameters of COD, phosphate, and
surfactant were 67%, 72%, and 63% respectively.
Keywords: cellulose diacetate membranes, laundry wastewater, flux,
rejection
