WebSubstituting perlite for other conventionally-used materials often has the effect of lowering the overall density of the well-cement mixture. The density of materials such as diatomaceous earth (DE), pozzolan, fly ash, and glass microspheres and beads typically ranges between 400 – 1,600 kg/m3 (25 – 100 lb/cu ft), whereas expanded perlite ... WebThis paper deals with the possibility of using perlite as a lead ion sorbent from industrial wastewater. Dynamic (laboratory column) operations were carried-out using beads, which were percolated by metals in a 2–10 mg·L−1 concentration range. To this purpose, lead ion solutions were eluted in columns loaded with different amounts of sorbent (2–4 g) …
