Filter media for iron removal

Sorbent is very efficient for tertiary treatment of sewage waters of the main and auxiliary shops of metal production including clean cycles at motor deports, oil tank farms, locomotive sheds, etc., to remove inert charging in high – rate trickling filters.

The sorbent regeneration no requires the use of any chemical reagents. For regeneration is necessary periodically to flush sorbent by water or water – air (which is more effective). In operation, the sorbent is not spent. It is a very durable material.

«Sorbent AS» ‘is not processed further chemically active coatings based on manganese or other catalytically active metal, which eliminates the probability of failure for exhaustion or flushing data surfaces. This is one of the fundamental difference among “sorbent AS” on downloads such as «BIRM», «Greensand», “Greensand”, etc. The catalytically active components included in the structure of the sorbent granules evenly that enables efficient operation even during the breaking of the pellets.

Benefits

• long service life with low annual loss of less than 2%

•easiest sorbent is not out of the activated carbon produced in Eastern Europe and CIS

“Sorbent AC” functions with all kinds of oxidants: ozone, sodium hypochlorite, potassium permanganate, and others.

• it is working in the presence of hydrogen sulfide

•operates at = 6.5 (to load BIRM minimum 6.8)

preliminary chlorination does not reduce the activity of “Sorbent AS”

•It increases the water to 1.0-1.5 units depending on the starting value of water, which enables the effective removal of iron

•increases the life of the ion exchange resins service cycle 4 times significantly reduces iron poisoning resins

•It does not form a biofilm on the surface of sorbent granules

•has a coagulating property is effective to reduce the concentration of residual aluminum

•steady performance sorbent filtration cycle up to 170 hours or more (experimentally worked 244 hours in the initial iron 6.5 mg / l in the industrial filter 2,0-0,6 FOV with guaranteed quality filtrate for iron less than 0.3 mg / L)
