This paper deals with the technology of ozonation together with sorption on activated carbons (AC) and its compliance with 12 principles of green chemistry. The report also provides an illustrative example of a drinking water treatment station with a capacity of 160 m3/h which purifies underground water from ions of iron by using ozone sorption technology and 12 principles of green chemistry. R&D, design, construction, and maintenance of the station are described. Our company LLC NVF ‘TIMIS’ was the first to propose an environmentally friendly method of disposal of residual products after purification of water by using them as components in the catalyst decomposition of ozone. The research work at Lomonosov Moscow State University has shown that ozonation with AC sorption technology reduces the concentration of total iron from 1.28 to 0.03 mg/L, reduces color grade and turbidity, provides disinfection and deodorization of water, and oxidizes organic and ions of iron more effectively than the oxidation of water by air or oxygen. This technology has successfully purified more than 8,000,000 m3 of underground water for the last 8 years.
