Abstract
The article considers the possibility of reducing the
man-made load on surface and ground waters in Lysychansk-
Severodonetsk industrial agglomeration caused by numerous
sludge collectors and tailings storage facilities of various
industries formed many decades ago. The paper provides
information on the location and technical condition of the sludge
collectors of the liquidated “LYSSODA” manufacture (Luhansk
oblast), the amount of waste currently stored in them as well as
the impact of these wastes on the quality of groundwater in the
area where the sludge collectors are located. The work shows one
of several possible options for using such wastes as a valuable
secondary mineral raw material for obtaining a marketable
product. The averaged data on the chemical composition of the
solid phase of sludge and indicators of the liquid phase
composition are given. According to the results of the analysis of
scientific and technical information, it has been found that such
wastes can ultimately be used for the production of anti-icing
reagents. The obtained results of research on the dependence of
the freezing point of working solutions on the concentration of
salts, including the added corrosion inhibitors (triethanolamine,
hexamethylenetetramine), indicate the feasibility of using soda
ash production waste to obtain effective liquid anti-icing reagents
without a mechanical component, while the optimal amount of
added corrosion inhibitors is 0.5 % wt. Such reagents can be used
both undiluted at temperatures up to minus 20 °C and
strengthened to 15–20 % wt. by calcium chloride at temperatures
up to minus 40 °C with consumption on highways at the level of
about 100 g/m2 of the treated surface.
