Adsorption of arsenic in water, adsorption of arsenic filter material

Adsorption of arsenic in water, adsorption of arsenic filter material

BKsorb

Type: Adsorbent

Adsorption peakpH：5-9

1. Introduction:The metal organic framework equipped with zero valent iron water purification filter FERROLOX-X can adsorb and remove various heavy metals, arsenic, phosphates, etc. from water. It has a specific surface area of 3000 ㎡/g, not only with a large adsorption capacity, but also with high removal accuracy.

2. Main functions:Adsorption removal of trivalent arsenic and pentavalent arsenic from water, and deep adsorption removal of phosphorus, vanadium, chromium (+3,+6), cadmium, mercury, copper, lead, nickel, etc. in water.

3. Physical and chemical properties

Physical state: Solid particles

Appearance odor: No special odor

Solubility in water at 20 ° C: insoluble

Volume weight (kg/m3): 685-690 kg/m ³

粒径： 0.5-2.0 mm

Arsenic adsorption capacity: 20-30g/L (related to arsenic concentration in water)

PH value: 5-9

Expected service life: 2-5 years

Water inlet requirements:

1. No large particles larger than 10 μ m

2. The water is basically free of substances such as oil that may adhere to the surface of the filter material

3. Minimize silica as much as possible

4. Component information

4.1. Skeleton: Iron Hydroxide

4.2. Functional group: hydroxyl active iron

5. Stability and reactivity

5.1. Treatment: Stable at room temperature.

5.2. Storage: Store in a sealed container, in a cool, dry, and well ventilated place to prevent physical damage.

6. Operating conditions:

Downstream filter bed height: 800mm -1200mm

Downstream floating bed space: 35% -50%

Applicable pH: 5-9

Peak effect pH: 6-7.5

EBCT:>120 seconds

Downstream working flow rate: 10-20m/h

Operation prompt

The front end of the BKsorb filtration unit needs to undergo pre filtration until the water does not contain particles larger than 10 μ m. For different pollutants with different adsorption peak pH values, the pH value of the influent is adjusted as follows:

Phosphate: 6-7

Arsenic: 6.5-7.5

Heavy metals: above 7

Other: According to the pollutants, please contact us for advice.

Water outlet:Stable before adsorption saturation0.01ppmBelow, trace amounts of arsenic, phosphorus, vanadium, and heavy metals can be almost undetectable.
