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 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 recovered in 2017 from natural aggregates deposits (Opolskie Voivodeship) amounted to 12,948.68 tonnes (including 2,882.30 tonnes of sands and 10,066.38 tonnes of gravel), from foundry sands deposits (Opoczno area) to 56,110 tonnes and from glass sands (the vicinities of Tomaszów Mazowiecki) to 19,346 tonnes of filtration gravel and 8,788 tonnes of special gravel.
