A porous, rough-surfaced pumice stone media and activated carbon are the main filter media that I use in the Nature Aquarium. The dirt that is taken into the filter with water is trapped by the rough surface of the filter media and removed from the water. The dirt that is dissolved in water is adsorbed and removed by activated carbon.

Tannery wastewater contains the most hazardous pollutants. Therefore, identifying potentially efficient, low-cost and locally available filter media as an adsorbent for the treatment of tannery wastewater is critical. The aim of this study is to identify and assess the ability of identified adsorbents and compare their efficiency. The volcanic rocks of …

The potential for water filtration that these materials have is due to the fact that they have two levels of porosity, one of the materials itself and the other of the filter bed. Among the most relevant materials are granular activated carbon, dolomite, calcite, limestone, sandstone, pumice, and zeolites (Farhaoui and Derraz, 2016).
