Results of studies focused on the creation of efficient ceramic filters for multi-stage treatment of industrial and
household wastes based on natural alumosilicate and technogenic starting materials are presented. The influ
ence of the individual components of the charge on the basic structurally sensitive properties of ceramic mate
rials is established. Compositions of compounds for the fabrication of the carriage of filters with tubular con
figuration are considered.

The third millennium in the modern history of mankind
is the era of scientific and technological progress. The actual
result of this process has been large-scale industry, which by
reprocessing natural resources (mineral, water, etc.), has pro-
vided mankind with the riches of civilization. However, im-
provements in the conditions of man’s life are accompanied
by depletion of natural resources and pollution of the bio-
sphere with wastes from the processing of raw materials
which are not needed by industry and which are in the form
of liquids (run-off), gases, and solid substances. As a result,
without actually wishing to do so, man changes the environ
ment, introducing irreparable damage to the natural world.
An increase in the ecological cleanliness of the production
process through the creation of closed and waste-free techno
logical cycles is a critical technological and engineering task.
Plants with ceramic filters for the treatment of waste
gases as well as process water, industrial wastes, drinking
water, etc. are needed at industrial enterprises of different
configurations . With the use of ceramic filters it becomes
possible to create closed water use systems and thus reduce
the intake of natural water for production needs and indus
trial processes as well as discharges of industrial wastes into
bodies of water. If the overall demand for natural water can
not be eliminated, the use of plants equipped with ceramic
filtration elements will make it possible to implement
multi-stage treatment of any type of discharge, including dis-
charges contaminated with chemical agents, petroleum prod-
ucts, and inorganic salts, by virtue of the chemical stability,
heat resistance, and stability of ceramic. The efficiency
gained with the use of ceramic filters has been demonstrated
by many years of study. A basic drawback is the high cost of
ceramic filters and membranes, due, in particular, to the ex-
pensive raw material employed and the high energy con-
sumption for the production for articles [2, 3].
Studies have been carried out in the Department of Ce
ramics and Refractories, Novomoskovsk Institute, Mende
leyev Chemical Technological University of Russia aimed at
creating ceramic filtration elements for processes of micro-
and ultra-filtration. The studies have basically involved the
use of different natural alumosilicate stock, including that
from a local source of raw materials, in particular, weak clay
from the Novomoskovsk deposit (Table 1) and certain other
multi-mineral clays (for example, Kimovsk clays), since pre
vious studies have shown that it is in theory possible to use
clays as the basic component of a charge for the production
of filtrating ceramic .
