AFM® ng (Activated Filter Media) filter features
AFM® ng produced with a special stimulation process
Features of AFM® new generation glass filter media : specific hydrophobic surface. For better absorption of microplastics and organic matter. AFM® ng is produced with a special activation process to increase the contact surface and is hydrophobic (nonionic). Dryden Aqua developed AFM® ng to remove microplastics and organic matter from water. This is because uncharged substances or particles are difficult to dissolve in water and it usually floats in water similar to oil. These substances are absorbed by the uncharged surface, that’s a hydrophobic surface. Various organic substances are precursors that can become trihalomethanes (THMs), including chromophores. Thanks to the unique properties of AFM® ng with its hydrophobic surface and mesoporous structure, AFM® ng can filter organic matter approximately 50% finely than sand filtration. When it can filter better, that means less use of chemicals to kill germs. The resulting water will be cleaner, healthier, decreased odor and reduce the cost of water maintenance.

Features of AFM® ng, New Glass Filter Media: New Size
- AFM®Grade 1 ng AFM® 0.4 mm. – 0.8 mm. (bags of 25 kg.)
- AFM®Grade 2 ng AFM® 0.7 mm. – 2.0 mm. (bags of 25 kg.)
- AFM® Grade 3 AFM® 2.0 mm. – 4.0 mm. (bags of 25 kg.)
- AFM® Grade 1 AFM® 0.4 mm. – 1.0 mm. (bags of 25 kg.)
- AFM® Grade 1 ng AFM® 0.4mm-1.2mm – Mini Bags 11.3 kg.
Thanks to the innovation of Dryden Aqua, the company researches and scales AFM® glass filters to be smaller and more efficient in water filtration. Can filter down to 1 micron. The new glass filter AFM® 1 ng has a filtration efficiency similar to that of AFM® 0 glass filter media.
Therefore, the new glass filter media AFM® 1 ng can be used instead of the glass filter AFM® 0.
With a smaller size make filtering efficiency of AFM® ng glass filter media increased
Addition ratio AFM® new generation glass filter media: 50/50
tank size < 800 mm.
Filter tanks with a diameter of less than 800 mm or 80 cm.
AFM® 1 ng : 50%
0.4 – 0.8 mm.
AFM® 2 ng : 50%
0.4 – 0.8 mm.
* New AFM® 2 NG ratio will help support foundation. It also serves as a filter as well.
tank size > 800 mm.
AFM® 1 ng : 50%
0.4 – 0.8 mm.
AFM® 2 ng : 25%
0.7 – 2.0 mm.
AFM® 3 : 25%
0.7 – 2.0 mm.
Why the proportion is required at 50%: 50%?
1.) Better water filtration efficiency
Filtration speed: 20m/h
Temperature 25 °C
particle size 1 micron
- AFM® ng 70/30 94.6%
Original proportion 70/30 AFM® new generation glass filter media. Can filter from 1 micron at 94.6%
- AFM® ng 50/50 93.8%
New proportion 50/50 AFM® new generation new glass filter media. Can filter from 1 micron at 93.8%
- AFM® Standard 100/0 60%
Hydroponic surface makes AFM® new generation glass filter media better than conventional AFM®, especially at finer ranges above 5 microns.
particle size 5 micron
- AFM® ng 0/100 ( 100% Grade 2) 90%
- Sand 16×30 73%
When comparing AFM® 2 ng with sand
AFM® 2 ng is more effective at filtering than sand at 90% at 5 µm whereas sand at 5 µm is only 73%.
New proportion of AFM® 2 ng in addition to supporting/foundation. And it also performs an excellent water filtration function.
2.) Better Backwash efficiency
Water Temperature 25 °C
70/30
70/30
70/30 AFM® ng ratio, each layer of the filter media is greatly expanded. There is a chance of losing the filter. or cause the filter substance to come out of the filter tank when the filter backwashing speed is more than 40 m/h
50/50
50/50
50/50 AFM® ng proportions for each layer of filter media. There will be very little expansion due to less AFM® 1 new generation glass filter media.
3.) Efficiency, needed pressure of water for filtration is reduced
70/30
50/50
Graphing measures the pressure loss value. Compared to the 70/30 AFM® ng green ratio and the 50/50 AFM® ng blue ratio, the 50/50 AFM® ng ratio has less pressure loss in the filter tank. resulting in more energy saving than the original proportion
AFM® 1 ng
0.4 – 0.8 mm.
AFM® 2 ng
0.4 – 0.8 mm.
