Comparison of water filters features

The comparison of water filters features of used in the market for filtering turbidity and heavy metals

Compare the properties of AFM® glass filters and others (Anthracite, Manganese Zeolite and Manganese Green sand).

Features	AFM®	Anthracite	Manganese Zeolite	Manganese Green sand
Made from	Made from used glass Bring to grind and stimulate electric charge	Made from Anthracite	Made from Zeolite stone and coated with Manganese Oxide.	Made from natural sand and coated with Manganese Oxide.
Use for waste treat/elimination	Able to remove rust > 95% Can remove manganese rust > 80% Able to remove arsenic > 90% Can filter bacteria, organic matter, phosphate, chromium, can absorb fat up to 100 mg/L. Able to reduce the SDI value to less than 3 Able to absorb chemicals such as weed killers	Absorb sludge, suspended solids, just like sand	Remove iron rust, manganese and hydrogen sulfide rust	Remove iron rust, manganese and hydrogen sulfide rust
Special Features	AFM® Grade 1 can filter finely up to 5 microns. AFM® Grade 0 can filter fine up to 1 micron It is a water filter with a high negative charge and positive charge. Anionic (Cationic), which helps to accelerate the precipitation (Coagulants) of steel, aluminum. Positive ions (Anionic), which helps in coagulation (Flocculants) of steel and aluminum Can generate free radicals to cause High Redox Potential	Lighter than sand Filters up to 10 microns	Filters up to 10 microns It is a positively charged filter Able to oxidize iron and manganese dissolved in water to insoluble form and filtered out of the system.	Filters up to 10 microns It is a positively charged filter Able to oxidize iron and manganese dissolved in water to insoluble form and filtered out of the system.
Cleaning or Rejuvenation	Use normal water Backwash / rejuvenation Takes backwash only 3-5 minutes	Use Normal Water Backwash	Use water mixed with potassium permanganate to restore the condition (Regenerate) Can Regenerate IR (Intermittent Regeneration) takes about 45-75 minutes	Use water mixed with potassium permanganate to restore the condition (Regenerate) It is not recommended to regenerate with IR
Notes	Smooth surfaces are not suitable for bacteria to adhere to as habitats. In some applications, foreign odors may arise from contaminants in the water such as bacteria, tannins, organics and chlorine. It may be necessary to install a carbon filter to absorb the odor and adjust the taste of the water	–	If you want to filter turbidity, it will be used with Anthracite called Multimedia Filter Due to the rough skin, it is easy to harbor bacteria	If you want to filter turbidity, it will be used with Anthracite called Multimedia Filter Due to the rough skin, it is easy to harbor bacteria
