– Effective filtration speed: 10-20 m/h.
– Required backwash speed: 30-40 m/h
– Specification:   20 kg/bag
– Origin: USA

Specification:

– Acts as an insoluble catalyst to remove Iron, Manganese, Arsenic and some heavy metal compounds dissolved in water.
– Surface can be easily cleaned by backwashing to remove precipitates
– Characteristics: granular, dark brown, hard, dry loose
– Hard to dissolve in iron reactions, long using time and low material consumption
– Any type of heavy metal present in the water will also affect the health of the user. Because these metals cannot be absorbed by the body nor excreted.
– Specialized birm beads remove Iron, Manganese, Arsenic and some heavy metal compounds dissolved in water.
– Birm beads is a MnO2 manganese dioxide coated aluminum silicate filter material. This coating is a highly oxidizing compound that acts as an insoluble catalyst to enhance the oxidation reactions of Fe2+ to Fe3+ and produce precipitated Fe(OH)3 iron hydroxide (alum) and adhere to the surface. birm seeds in layers.
– The surface of birm seeds can be easily cleaned by backwashing to remove precipitates, so it is necessary to have a filter pump with sufficient pressure to dislodge iron precipitated from the grain surface.

Advantage of birm:

Using birm particles is an effective and economical filtration solution compared to other current filter materials:
– High catalytic efficiency leads to very effective filtration of alum and manganese in groundwater
– Hard to dissolve in iron reactions, long using time and low material consumption
– Safe for users because it does not dissolve in water
– Wide temperature range
– Can be used in both gravity filtration or pressurized water treatment with a composite filter column or a stainless steel filter column using a control valve
– No need to use chemicals for material regeneration
– Birm increased capacity with existing clean water treatment plants and stations by 1.5-2 times without the need to install new filter columns or build condensate and settling tanks.
