AFM® Aktiviertes Filtermaterial
AFM® Aktiviertes Filtermaterial hergestellt aus grünem und braunem Recyclingglas für eine noch feinere Filterleistung. Reduziert den Verbrauch an Desinfektionsmitteln und sorgt für kristallklares Wasser.
AFM® (Activated Filter Media) ist das Ergebnis von 35 Jahren Forschung & Entwicklung und ersetzt den Sand oder Glassand Ihres Filters. Es verbessert die Filterleistung um mindestens 30 % gegenüber Quarz- oder Glassand und reduziert somit den Verbrauch an Desinfektionsmitteln.
Einzigartige Vorteile:
- Kristallklares Wasser: Filtriert ohne Flockung bis 1 Mikron Filtrationsschärfe
- Gesündere Luft: Reduziert schädliche Chlornebenreaktionsprodukte und Chlorgeruch um 50%
- Geringere Kosten: Reduziert Rückspülwasser und Chlorverbrauch
- Nachhaltige Filtration: Besitzt eine längere Lebensdauer als alle anderen Filtermaterialien
- Sehr lange Haltbarkeit: hält 20 – 30 % länger als Quarzsand
- AFM® beeinträchtigt nicht die Wirksamkeit des Flockungsmittels, der Entkalkungsmittel und der Desinfektionsmittel des Filters
- Für alle Beckenarten (Folien, Beton, GFK etc.) und Desinfektionssysteme wie z.B. Chlor- oder Salzwassersysteme geeignet
Was bedeutet AFM® Aktivierung?
Das gewaschene, farbsortierte, gebrochene und gesiebte Glaskorn durchläuft den dreistufigen chemischen und thermischen Aktivierungsprozess. Die Aktivierung veredelt die Glasoberfläche, was die einzigartigen Filtrationseigenschaften ermöglicht.
Der Aktivierungsprozess schafft eine hydrophobe – also wasserabweisende – Oberfläche. Die meisten organischen Stoffe sind hydrophob und werden am besten mit einem hydrophoben Filtermaterial gefiltert. AFM®-ng kann Partikel bis zu 1 Mikron Größe und ca. 50% mehr organische Substanzen als Sand und andere Glasfiltermedien ausfiltrieren.
Anwendung:
Bestimmen Sie, welche Gesamtmenge Sie für Ihren Filterbehälter benötigen.
AFM® hat eine geringere Schüttdichte als Sand (1.250kg/m3) und die Menge nach Gewicht sollte daher um 15 % reduziert werden.
Beispiel: 25kg Sand = 21kg AFM® (Sandmenge x 0,85)
- Bei Filteranlagen mit einem Durchmesser unter 400 mm sollte nur AFM®ng Grade 1 benutzt werden
- Für Filter mit einem Durchmesser zwischen 400 mm und 800 mm und für alle Filter mit Düsenböden, unabhängig vom Durchmesser, verwenden Sie 50% AFM®ng Grade 1 und 50% AFM®ng Grade 2
- Empfohlene Filtrationsgeschwindigkeit: 15 bis 30m/h
- Empfohlene Rückspülgeschwindigkeit: 40 bis 50m/h
| Sandmenge in kg | Ersatz AFM® in kg | ca. 50% AFM® Korn 1 in kg | ca. 50% AFM® Korn 2 in kg |

Füllen Sie die Hälfte des Filterbehälters mit Wasser, um den Filterboden zu schützen, bevor Sie AFM-® in den Filter füllen.
Achtung: Füllen Sie nun zuerst die angegebene Menge von AFM® Korn 2 und danach AFM® Korn 1 in Ihren Filterbehälter.
Nach der Befüllung lassen Sie AFM® entweder für 24 Stunden im Filter ruhen um richtig nass zu werden, oder Sie gehen direkt auf Filtration ohne vorherige Rückspülung. Fahren Sie mit der ersten Rückspülung frühestens 24 Stunden nach der Installation mit einer Geschwindigkeit von 40 - 50 m/h (m3/h/m2) fort.

From a Long Time Hard Sole Dress Shoe Wearer, These are a Must Have!
Size: 12, Color: Blue
I have been wearing hard sole dress shoes for decades and with the full COVID shift to dressing super casual in a professional work environment, I was in the market for some more casual let dressy shoes that were a heck of a lot more comfortable and flexible than my hard soles so I thought I would give this brand and style a try. Oh man, I'm in love. These give you that dressier look yet you can totally dress them down with jeans or cordouroys, so versatile. As I did with my hard soles, I inserted one of my Nike Air in soles and man, these are so comfortable I bought navy and brown! I usually wear these with thin dress socks and they go perfectly with any type of suit set, a no brainer purchase here. I'm a 12 and bought a 12, perfect fit, not to skinny, not to wide, just right. Bottom sole grip is impressive, never felt unstable, solid rubber sole here. I decided to lace them up so there are not tying and the tongue does slip down sometimes so with this feature, best to use a metal shoe horn, then it's super easy to slide them on, they seem to take a beating and remain clean too, I've definitely scuffed them up against many things and still no damage, it's crazy, must have a great finish. NOTE TO Note to MANUFACTURER/SELLER - You need to make a version in GRAY in this specific style and I will buy them instantly, and I assure you they will be incredibly popular! Really not sure why there isn't more colors in these like gray, shades of gray, maybe red, lighter blue and maybe some with different tones in standard colors. Casual dress shoe wearers are looking for new and exciting bold colors so this is the perfect shoe type to deliver on that.

Finally, a dress shoe that actually feels like a sneaker!
Size: 8.5, Color: Dark Brown
I was honestly super skeptical about buying shoes on Amazon, especially "dress sneakers." Usually, they either look incredibly cheap in person or they completely destroy your heels within an hour. I am so glad I took a chance on these Bruno Marcs.
I commute to campus and take the bus almost every day, so I end up doing a ton of walking. I needed something that looked sharp and put-together, but I absolutely refused to sacrifice comfort for a long day on my feet. These completely hit the mark. Right out of the box, there was zero break-in period—no stiffness, no pinching, and no blisters.
They are incredibly lightweight, and the material actually looks premium, not like that shiny, fake plastic you sometimes get at this price point. The traction on the bottom is surprisingly good too, which is a lifesaver when I'm rushing to catch my bus on rainy mornings.
If you’re on the fence, just get them. It’s rare to find a shoe that balances looking professional with feeling exactly like your favorite weekend sneaker. Easily one of the best wardrobe purchases I've made in a while!

High quality, perfect color and very nice price!
Size: 14, Color: Brown, Size: 14, Color: Brown
I bought this shoes for my husband's Christmas present, so he didn't try yet. So far, the color is perfect! I feel like he can wear this shoes with different outfits, for the price it seems hight quality, it is not heavy at all.
The shoe features a soft, comfortable lining and the sole is perfect because it is non-slip.

These fit very nicely, are comfortable, and work for my wide feet!
Size: 12 Wide, Color: Brown
Once I learned while shoe shopping in my youth that I needed wide-sized shoes, I wasn't able to easily choose from any shoes I saw in the store. I usually have to go find the wide widths and have to deal with the limited styles they have. Shopping online has been hit and miss, too. Sometimes, shoes are advertised as wide width, but end up still being too narrow.
These shoes fit me just right. They were not too tight at the toes, gave good width at the arch, and the opening was large enough that I didn't have to undo every single lace just to get my foot in. They also look nice, and I'm sure will take a decent polish.
Also, note that this does say it's an Oxford shoe, but it does have the open lacing and is more of a derby-style shoe. This also helps with sizing for my wide feet. If I didn't already have a pair of black shoes, I'd look at picking one of these up.
My only reservation with these is that the soles are not dark-colored to complement a more formal style. I feel the white makes them a little more casual. The sole is also more transparent/opaque coloring at the heel and underneath, which you can kind of see-through, so keep that in mind. It's not fully clear, but is kind of transparent, which I was not expecting. I think it also shows where it picks up dirt as you wear it. Just more of a style cue one way or another.
As a reference, I buy the 4E wide and Extra Wides in New Balance and Skechers. I also have a hard time getting any good fit in Nike shoes.
