An overview of water treatment technologies employed at the heat-and-power plants of
Astrakhan is made by the authors. Water treatment facilities are in a very poor condition. As a result,
heat-and-power equipment suffers from considerable scaling, fouling and corrosion problems. New
membrane technologies, including ultra-filtration and nano-filtration, seem to be a promising way to
improve the water quality. The evaluation of the present-day water treatment efficiency with account
for the effective standards and requirements makes it possible to conclude that new pressure-driven
membrane processes must be implemented at heat-and-power plants.
Membrane technologies will improve the quality of water processed at operating power generating
stations or the quality of the water supplied to new structures of the city of Astrakhan; they will
reduce the reagent consumption rate and improve the role of water purification systems as barriers
that prevent water contamination. Besides, membranes ensure a high efficiency of turbidity removal,
and membrane facilities are small and simple in operation. The main difference of membrane technologies
if compared to conventional sedimentation and filtration systems consists in the high quality
of water irrespective of fluctuations in the temperature and composition of inflowing flows of water.
Authors are going to continue their research into the issue of potential wide-scale introduction
of newly developed techniques at the heat-and-power plants of Astrakhan to provide clear water to
boiler plants at low operational costs. The research results indicate that the above approach has a
strong potential in terms of water treatment in the power industry. The new procedure was developed
by the authors to identify and project the scaling and fouling rates within membrane modules
and to predict the membrane performance (permeate flux) depending on the feed water quality and
modes of operation.
