Filtration gravel

Filtration sand and gravel are used in purification of potable water and sewage treatment. The material used for these purposes is specifically graded pure quartz gravel. The two deposits of filtration gravel hitherto proven in Poland are not exploited at present (Nowy Dwór and Panoszów deposits).

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

In 2011, total amount of filtration sands and gravels recovered from processing of natural aggregates in the opolskie voivodeship was 10.40 thousand tonnes, from processing of foundry sands from the Opoczno area – 80.18 thousand tonnes, and treatment of glass sands from the Tomaszów Mazowiecki area – 30.37 thousand tonnes.
