Filtration gravel

Filtration sand and gravel are used in a purification of potable water and a sewage treatment. The material used for these purposes is a specifically graded pure quartz gravel. The deposits of filtration gravel have been documented in the area of 2 Voviodeships – Pomorskie (Nowy Dwór deposit) and Śląskie (Panoszów deposit). Their total anticipated economic resources are equal 273 thousand tonnes (Table 1). The deposits have not been exploited so far.

The whole domestic demand for filtration sand and gravel is fully covered with the material recovered in the processing of ennobling the natural aggregates from deposits situated in Opolskie Voivodeship, foundry sands from the Opoczno area and glass sands from the vicinities of Tomaszów Mazowiecki.

The total amount of filtration gravel and sands obtained in 2020 from Rakowiczki deposit in Opolskie Voivodeship amounted to 6,074.845 tonnes (including: 4,256.090 tonnes of filtration sands and 1,818.755 tonnes of filtration gravel), from the foundry sands deposits in the vicinities of Opoczno amounted to 59,236 tonnes, whereas from the glass sands deposits in the vicinities of Tomaszów Mazowiecki – 18,705 tonnes of filtration gravel and 5,843 tonnes of special gravel.
