MetSorb HMRG media’s adsorptive capacity is 220 grams of arsenic per kilogram of HMRG adsorbent at a pH level of 7. It yields 40,000 bed volumes of capacity at an inlet concentration of 40 parts per billion (ppb) of arsenic, at 1.6 minutes of empty bed contact time (EBCT), and a breakthrough of 10 ppb.
Adsorption, the binding of molecules or particles to a surface, must be distinguished from absorption, the filling of pores in a solid. The binding to the surface is usually weak and reversible. Just about anything including the fluid that dissolves or suspends the material of interest is bound, but compounds with color and those that have taste or odour tend to bind strongly. Compounds that contain chromogenic groups (atomic arrangements that vibrate at frequencies in the visible spectrum) very often are strongly adsorbed on activated carbon. Decolourisation can be extremely efficient by adsorption and with negligible loss of other materials.
| The most common industrial adsorbents are activated carbon, silica gel, and alumina, because they present enormous surface areas per unit weight. Activated carbon is produced by roasting organic material to decompose it to granules of carbon – coconut shell, wood, and bone are common sources. Silica gel is a matrix of hydrated silicon dioxide. Alumina is mined or precipitated aluminum oxide and hydroxide. Although activated carbon is a magnificent material for adsorption, its black color persists and adds a grey tinge if even trace amounts are left after treatment; however filter materials with fine pores remove carbon quite well. |
MetSorb® HMRG is a highly effective granular adsorbent that removes arsenic III & V, and a wide variety of heavy metals including Lead, Cadmium, Copper, Chromium+6, Selenium, and Zinc from aqueous sources. MetSorb adsorbent technology utilises a patented Titanium compound to adsorb both forms of arsenic as well as a wide range of contaminants in water. The increased surface area afforded by Titanium coupled with advanced pore volume provides excellent kinetics of adsorption. MetSorb® maintains a higher capacity and a lower level of ion interference than competitive iron and alumina-based products.
