Special High Temperature Resistant Elements
Many filtration conditions are with feed slurry temp. Of upto 60-70 degree cent. & working pressure upto 4-5 kg./cm2. But there are such requirements where filtration take place with higher temp. Then 70 degree cent.
Now, if you apply higher temperature beyond 70 degree cent., the normal pp filter elements will not work. Pp material will soften gradually at a higher temp. Under long time filtration condition, this may results in bending of pp filter elements, developing crakes or breakage of the elements.
