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 2019 from the foundry sands deposits in the vicinities of Opoczno amounted to 47,561 tonnes, from the glass sands deposits in the vicinities of Tomaszów Mazowiecki – 19,821 tonnes of filtration gravel and 6,769 tonnes of special gravel, whereas on the natural aggregates deposits in Opolskie Voviodeship we have not received the data.
