AB - The treatment of waters using filtering process through sintered porous ceramics based
on diatomite and kaolin is reported. The water samples were prepared in low = 50%,
medium = 100% and high = 150% concentrations, taking as reference point the
maximum value allowed according to the resolution 2115 - 2007. The treated
parameters were alkalinity; hardness to calcium, magnesium and total; chlorides;
sulfates and total iron. The porous ceramics were formed by slip casting in plaster mold,
from pastes with weight percentage of 50% recycled diatomite from the beer industry,
40% kaolin and 10% calcium carbonate. The particle sizes of the ceramic powders were
the passed through ASTM 200 sieve. The drying of the ceramics was carried out at
room temperature for 24 h, then by forced circulation oven Memmert UF-110 at 100 °
C for an equal time. The sintering of the ceramics was carried out in Vulcan D-130
electric muffle, at a maximum temperature of 1000 ° C for two hours, with a heating
ramp of 10 ° C/min. The morphology of the ceramics was studied using scanning
electron microscopy (SEM), while the physic ceramic analyses was evaluated
according to ISO 10545-3 standard. Our results, reported what porous ceramics
efficiency for the removal of chlorides up to 50%, while elimination of sulfates was
approximately 43%, on the other hand, the total iron was removed up to 95%, likewise,it was evidenced that ceramics are not efficient in the treatment of hardness and
alkalinity of waters with high concentrations
