Abstract
The paper considers the investigation of quartz sand as a filter material for water treatment systems of heat supply installations and to the development of quantitative criteria for forecasting its service life. The quartz sand filter is transformed into a composite material covered with aluminum and iron oxides, which are formed because of adsorption and deposition of ions from the source water during operation.
With the methods of electron microscopy and energy dispersion analysis it has been found that when a filter is operated on source water with an Al ≈ 0.58 mg/l and Fe ≈ 0.44 mg/l, there is a significant change in the microlattice surface of the sand particles with the development of the micropore. The authors established that the achievement of mass proportions of aluminum and iron in quartz sand of the 11.78 and 7.11 % order is an indicator of the maximum capacity of the filter adsorption and a justification for planning its replacement.
The proposed approach enables a transition from a calendar‑based maintenance schedule to a predictive management of the filter’s service life, prevents the exceedance of permissible concentration limits of contaminants in network water and the optimization of costs for water preparation.
