Filtration is the process of removing suspended objects from the fluid by passing it through a porous filter. In this study porous ceramic water filter was preparation from Iraqi local porcelanite and Iraqi white kaolin with ratio (10%) as a binding material, and natural additives )wheat flakes( with ratio (5,10,15,20,25, and 30) %. Ceramic materials used in the manufacture
of the filter are environment – friendly materials and harmless. Filter is not expensive and easy to prepare, the specimens were formed by dry pressing then fired at (1200) ˚C, to evaluation of prepared filters the following tests were performed, linear shrinkage, loos in mass, apparent porosity, water absorption, apparent density, permeability as physical properties, compressive strength and diametrical strength as mechanical properties. The result shows that the linear shrinkage decreased to 0.6 %, loos in mass increased to 24.25 %, apparent porosity increased to 55%, water absorption increased to 50.99%, apparent density decreased to 1.07(g/cm3), permeability increased to 0.131(cm2/ bar. min), compressive strength decreased to 1 (MPa) and diametrical strength decreased to 3 (MPa) with adding ratio (30%) of wheat flakes (W.F), scanning electron microscopy (SEM) using to studying the microstructures which showed homogenies distribution of pores form a net in filter, adding wheat flakes with (30) % give highest pores.

Two processes were employed for forming, specifically, slip casting and semi-dry press were used to manufacture ceramic filters from local raw materials, red clay and combustible materials (sawdust and rice husk). Different proportions of additives were used as pores forming agents to create porosity in ceramic filter. Dried filters were fired at temperature to 1000°C.
It was found that the forming technique and additives have great effect on the physical properties of the produced ceramic filters. The slip casting technique was more suitable procedure for producing a porous ceramic filter. As well as, porosity increased as percentage of the combustible materials increased.

This paper deals with the elaboration of porous ceramic pots with raw clay
materials and rice husks for water filtration. The basic raw clays have been
mixed with rice husks at different ratio 10% and 15% weight (wt) and sintering
at 1200˚C, 1300˚C and 1400˚C for 30 minutes. The elaborated pots have
been tested for their densification properties and filtration flow. The mineralogy
and microstructure of pot have been also studied to explain the different
results. The pot with 10% wt rice husks and sintering at 1300˚C during 30
minutes presents a sufficient porosity and mechanical strength to be used for
water filtration.

Firing Temperature and Shrink Tests

CWF Clay Test
Test tiles 2cmx10cmx0.5cm



The first round of tiles for the filter clay temperature and shrinkage tests. Over 60 tiles to test at 925 950, 975, and 1000 degrees Celsius. We were sent between 250 and 500 grams of each sample, which turned out to be a little small. It took 100grams to make 4 tiles 2cmx10cmx5mm thick. and each time the particle analysis test was preformed we used 100grams as well. The particle analysis test takes 24hours to complete, and the firings about 6 hours, not to mention the prep and wait times. Our scale turned out to be giving bad readings so it threw off a lot of the data we collected. now we begin again.
