Hydrolit Mg

Uses: De-acidification and neutralisation

Hydrolit Mg is a porous filtration media, comprising rounded grains chiefly of magnesium oxide.  It is used for the neutralisation of industrial waste waters and the de-acidification of potable waters, and is available in three sizes:

0.5 – 2.5, 2 – 5 and 5 – 10mm.

Typical Chemical Analysis

MgO … 70 – 75%

CaO … 4 – 5%

Fe₂O₃ … 3 – 4%

Al₂O₃ … 3 – 4%

SiO₂ … 3 – 4%

LOI … 16 – 20%

Bulk Density

1200 kg/m³ (0.5 – 2.5mm) or 1300 kg/m³ (2 – 5 and 5 – 10mm)

Consumption

Per gram of acid, including losses on backwashing (all figures are approximate):

Sulphuric acid … 0.63g

Hydrochloric acid … 0.85g

Nitric acid … 0.49g

Acetic acid … 0.52g

Carbon dioxide … 0.74g

For neutralisation of waste water, use of a filter bed with 20% Hydrolit Mg is recommended; for de-acidification of potable water the suggested figure is 10%.
