Reagent for water purification from heavy metals

Application of MagTreat allows to remove impurities of heavy metal ions from aqueous media.

When processing wastewater of plants (with high content of salts of heavy metals) using MagTreat the reduction of concentration of ions to the values of the MPC as in fishery ponds can be achieve.

MagTreat precipitates heavy metal ions as hydroxides and link formed colloidal suspension as well filtering sediments. Especially effectively remove such dangerous elements as copper, lead, cadmium, zinc, chromium, etc.

Mg(OH)2 ↔ Mg2+ + 2OH Me2+ + 2OH = Me(OH)2 ↓where Me2+ — ions Fe2+, Cu2+, Ni2+, Zn2+, etc.

Unlike other commonly used alkaline reagents such as caustic soda, lime and soda, the usage of MagTreat does not lead to excessive increasing of pH level during overdose of reagent.

MagTreat also successfully solves the problem of the removing of iron ions from water, and therefore prevents the deposition of iron oxides.
