The Inversand Company introduces GreensandPlus for water treatment and filtration, an enhanced version of the firm’s Manganese Greensand that processes and removes iron, manganese, arsenic, radium and hydrogen sulfide in municipal, industrial and POU applications. GreensandPlus has the same effective size, uniformity coefficient, density, weight capacity, backwash and pressure drop curve as Manganese Greensand, but is much more resistant to attrition and works well on waters that are low in silica, TDS and total hardness.
