Basics of designing of electrochemical oxidation unit have been stated. It was shown that main products of electrolysis of natural
waters can be only hydrogen, oxygen and chlorine. Analysis of oxidative capability of experimental electrochemical cell has been carried
out. It was shown that calculated constant of the unit during the process of deferrizing depends on current strength and content of
chloride in source solution.
Key words: natural water, reagentless methods, electrochemical oxidation.

Sorption properties of material on the basis of basalt fibers with applied catalytic active coating made of manganese oxide in dynamic
conditions during extraction of ions of manganese from water, have been studied. Comparison of received material with grained analogs
has been carried out. Method of its regeneration with the help of reagents has been suggested.
Key words: sorbent, basalt fibers, oxide coating, catalyzer, water purification from manganese, regeneration.

In recent decades, progress in development of installations for purification of wastewaters, sludge processing, utilization of household
waste in the whole world is closely connected with resource saving, increase of reliability and effectiveness of power supply. The most
important resource of energy saving is processing of sedimentation of wastewaters and organic constituent of household waste which
from the current point of view is a biomass which can be effectively converted in various types of energy, first of all by means of biological
anaerobic processing (methane fermentation) and further combustion of biogas. This direction in recent decade is widely developing
throughout the world in connection with constant appreciation of natural energy carriers (oil and natural gas).
Key words: biogas, ecology, energy saving, purification, water, nature.
