Filtration gravel

Filtration sand and gravel are used in the purification of potable water and the 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 (the Nowy Dwór deposit) and Śląskie (the 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 sand and gravel obtained in 2022 from the Rakowiczki deposit in Opolskie Voivodeship amounted to 5,533.16 tonnes (including: 4,036.345 tonnes of filtration sand and 1,496.815 tonnes of filtration gravel), from the foundry sands deposits in the vicinities of Opoczno amounted to 62,111 tonnes, whereas from the glass sands deposits in the vicinities of Tomaszów Mazowiecki – 11,926 tonnes of filtration gravel and 5,231 tonnes of special gravel.
