Activated carbon based on anthracite with high volumetric microporosity for water treatment


A new approach to the assessment of microporous structure and adsorption properties of activated carbon per unit volume has been substantiated. A few stage GAC technology for activated carbon production on the basis of anthracite has been developed. The qualitative characteristics of activated carbons made of anthracite from various regions of Russia have been studied and the affinity of their adsorption properties and strength characteristics is shown. The studies of adsorption properties of GAC (ground anthracite sorbent) activated carbon in drinking water treatment under static and dynamic conditions were carried out. The efficiency of activated carbon made of anthracite in removing heavy metal ions from wastewater from gold beneficiation plants is demonstrated. High adsorption capacity of GAC activated carbon both in relation to organic and inorganic pollutants in industrial water and wastewater treatment provides for its high efficiency in water supply and wastewater disposal systems. The study results showed that replacing sand or hydroanthracite media with active anthracite (eliminating the construction of a separate block with activated carbon) at the existing municipal water treatment facilities will provide for saving 150 billion rubles because the packed density of active anthracite is comparable to the packed density of quartz sand. Anthracite is not washed during filtration facilities backwash; with that both filtration of mechanical pollutants and sorption of molecular toxicants take place. As a result high quality drinking water is obtained without substantial expenditures.

Modernization of the Zelenogorsk Water Supply Station is a Stage of Realization of the Regional Program Pure Water


The following works have been done within the limits of modernization of the Zelenogorsk water supply station (St. Petersburg): reloading of high-rate filters with installation of the new drainage system TRITON improvement of water aeration system (enrichment with oxygen in a pan aerator), and automation of technological process. The technique of water treatment for manganese at the second stage of the process with the use of catalytic oxidation in pressure filters containing the three-layered quartz sand, pyrolusite, and anthracite media has been introduced. The quality of water treated at the Zelenogorsk water supply station after its modernization meets the requirements of the Russian and European standards at all points.

Construction of water treatment facilities in Diuny
and Molodezhnoe settlements of the Kurort District of Saint-Petersburg


In accordance with «The scheme of water supply and wastewater disposal of Saint-Petersburg for the period up to 2025 including the prospects up to 2030» SUE «Vodokanal of St. Petersburg» started building two water treatment plants in Diuny and Molodezhnoe settlements of the kurort District of Saint-Petersburg upon the project of «Lengiproinzhproekt» Institute. Underground water deposits of the «Solnechnoe – Diuny» and «Molodezhnoe» intermorainic aquifer located in the south-western part of the Karelian Isthmus were used as a water source. Underground water is characterized by the high concentrations of iron (up to 5 mg/l, manganese (up to 1 mg/l), and barium (up to 1.5 mg/l). As for the rest parameters artesian water meets the standards. Underground water is fresh, sodium bicarbonate by chemical composition with 0.06–0.27 g/l mineralization and less than 3 mg-eq/l hardness. The technology of removing iron, manganese and bromine from water in two-stage rapid filters with the use of catalytic oxidation in pressure filters of the second stage containing crushed pyrolusite media was introduced. The facilities designed and built according to the mentioned technology showed high process efficiency. As a result of the water treatment plants construction in Diuny and Molodezhnoe settlements the concentrations of iron, manganese and barium in the water supplied to the public water supply system meet the standards. The quality of drinking water meets not only Russian but also European standards.
