Powder Form Series

Powdered Activated Carbon (PAC) typically has a diameter less than 0.1 mm and an apparent density ranging between 23 and 46 lb/ft3, depending on the material used and manufacturing process. Iodine and molasses numbers are typically used to characterize PAC. These numbers describe the quantity of small and large pore volumes in a sample of PAC. A minimum iodine number of 500 is specified for PAC by AWWA standards.

Powdered Activated Carbon is used by water treatment plants on either a full time basis or as needed for taste and odour control or removal of organic chemicals. PAC can be fed as a powder using dry feed equipment or as a slurry using metering pumps. Dry feed systems are typically used for smaller dosages. PAC can also be mixed with water and fed as a slurry. Slurry systems are normally used when PAC is frequently added and the required dosages are high.

Powdered Activated Carbon is normally added early in the treatment process and is subsequently removed either by sedimentation or by the filter beds during backwashing. The PAC application point should allow for (1) an adequate contact time between the PAC and organics, and (2) avoid coating PAC particles with other water treatment plant chemicals. A minimum contact time of about 15 minutes is required for most taste and odour compounds; however, significantly longer contact times may be required for Methyl-Iso-Borneol (MIB) and Geosmin removal.

Powdered Activated Carbon dosages can range between 1 to 100 mg/L depending on the type and concentrations of organic compounds present. Dosages of 1 to 20 mg/L are typical for nominal taste and odour control. Application of Powdered Activated Carbon generates additional sludge which is not able to be regenerated as is spent GAC. Powdered Activated Carbon sludge will contain elevated concentrations of the contaminants removed and must be disposed in accordance with State and federal laws; however, it is not likely to be classified as a hazardous waste.

Amazing Facts

About Magical Activated Carbon

01

Medical Treatment

Its porous texture binds to toxins and prevents your body from absorbing them. It draws out impurities. That's one reason it's a staple in hospital emergency rooms. Doctors commonly use it as an antidote for food poisoning and drug toxicity.

02

Kidney Diseases

For patients with end-stage renal disease, activated charcoal may be a viable alternative to dialysis. It binds to urea and other toxins, reducing the number of waste applications that filter through your kidneys.

03

Deodorant

It can minimize body odor. For people who suffer from something called Fish Odor Syndrome, activated charcoal can bind to the stinky compounds the body produces and help reduce unpleasant odors. It is ideal as an underarm, shoe and refrigerator deodorant.

04

Gas And Indigestion

It helps to neutralize the liquids and gases trapped in the intestine and further ease pain, not required after gas. It has antiviral, anti-bacterial, anti-fungal and detoxifying properties which help in teeth whitening.

05

Skin Infections And Acne

Its anti-bacterial, properties help it absorb harmful microbes from wounds. It might also help stop the smell that comes from infections and can help with ulcers or bedsores.

06

Lowering Cholesterol

Some research shows that activated charcoal can keep your body from absorbing cholesterol. It helps in dropping the LDL, or bad cholesterol.

06

Preventing Hangovers

Though it doesn't seem to absorb alcohol very well, some research shows that drinking it at the same time as alcohol might lower blood alcohol levels somewhat.
