heavy metal removing

Heavy metals are the elements, which mass density amounts to more than 4,5 g/cm3.

Heavy metals include:

* Chromium – Cr
* Zinc – Zn
* Cadmium – Cd
* Cobalt – Co
* Manganese – Mn
* Copper – Cu
* Molybdenum – Mo
* Nickel – Ni
* Lead – Pb
* Mercury – Hg
* Selenium – Sn
* Vanadium – V
* Wolfram – W
* Iron – Fe
* Selenium – Sn

Some heavy metals, called microelements, are necessary for proper functioning of the living organisms, others do not have physiological role, but there are also metals and their compounds, which are redundant or even harmful for plants and human beings. Such metals are called toxic elements and compounds.

The amount of microelements in living organisms is usually trace, typical of each species. Deficiency or excess may harm the organisms.

The toxic metals contaminate the environment. The strongest toxic properties are shown by inorganic metal compounds, which easily dissolve and decompose, due to their abilities to permeate through cell membranes and penetrate bodily organs. They accumulate chiefly in kidneys, adrenal glands, liver, lungs, even in skin and hair. Such accumulation of toxic substances may lead to high blood pressure, cancer, kidney, liver or brain damage, or even mental aberration.

Heavy metals also contaminate the environment – soil, water, air and, directly or indirectly – together with food – get into human and animal organisms.

Our special filters, for removing heavy metals are used for some sewage sorts treatment, e.g. in electroplating plants. These systems are used in industrial plants, where heavy metal concentration exceeds acceptable level. Apart from these systems, selective ion exchange process may be conducted, as the standard water purification, supplement.
