When the oxidizing capacity power of the Manganese Greensand bed is exhausted, the bed has to be regenerated with a weak potassium permanganate (KMnO4) solution thus restoring the oxidizing capacity of …

technology for iron, manganese, hydrogen sulfide, arsenic and radium removal. Unlike other media, there is no need for extensive preconditioning of filter media or lengthy startup periods during which required water quality may not be met. GreensandPlus is an exact replacement for manganese greensand. It can be used in CO or IR applications and ...

Manganese greensand is somewhat smaller than typical filter sand, with an effective size of 0.30-0.35 mm and a specific gravity of about 2.4. The density of greensand at 38 Kg/ft³ considerably lower than pyrolusite, but greater than Birm. A vigorous backwash by air scouring is recommended.

Manganese Greensand is formulated from a glauconite greensand which is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration. Once dissolved iron and manganese come into contact with manganese filter media, they get oxidized and precipitate at the bottom of the filter bed.

Birm, Greensand, and Pro-OX Iron Filters: A Primer. The three most common systems available to remove iron from well water are back-washing iron filters that use one of three different media: Birm, Greensand, and Manganese Oxide (Pro-OX). Iron makes up 5% of the Planet's crust and is found in well water throughout the world.

The amount of flow and the amount needed to backwash the media are determined by the surface area of the media—depending on the tank diameter—not on the total area (cubic feet) of media.. A 12" diameter filter tank supports considerably greater gpm (gallons per minute) flow than a 10" diameter tank, but it also requires considerably more backwash …

Media manganese greensand memiliki kapasitas buffer oksidasi-reduksi yang tinggi sehingga dapat mentoleransi kelebihan oksidan yang dimasukkan kedalam sistem. Manganese greensand bisa dialiri dengan kapasitas air yang tinggi tanpa mengurangi kekuatan nya untuk mengikat zat besi dan zat mangan.

The removal performance of the greensand media for Fe(II) differed to that for Mn(II), particularly for the coated media (GS1 and GS2) (Fig. 5). Firstly, the GS1 and GS2 media were shown to effectively remove Fe(II) without any activation method employed, which was not the case when manganese was in solution ( Fig. 3 ).
