gravel is utilized as support beds and it is manufactured in ranges of sizes of of 2x1 ½ , 1x ¾ , 1/2 x ¼ , 1/4 x 1/8, 1/8x1/16.

It is manufactured from glauconite green sand to retain iron, manganese and hydrogen sulfur present in water by oxidizing and filtering. It regenerates with a diluted solution of permanganate of potassium.

Granualr medium of manganese dioxide used to retain iron, manganese and hydrogen sulfur present in water by oxidizing and filtering. It regenerates with a diluted solution of permanganate or potassium and has a lower density than the green sand.

Mineral of manganese dioxide that acts as a catalizer in the retention of hydrogen sulfur, iron and manganese. It doesn’t require chemical regeneration but it is necessary to add an oxidant to the water.
