Hello from Sweden! Up North we have - 12 oC and sunshine, 1.2m of snow :)

Sorry forgot to say .. It's Johan from Vattenbutiken Åre, North Sweden.

In the backwash time of 3 minutes, is the slow start and slow going down included as time? Or is the pump in the case going up to 100% at once?Great seminar BTW!

What about layering for filters that are exactly 800mm?

did these free radicals oxidize our skin?

Pressure drop of AFM standard (which stays 70/30%?) is then equal to new layering with AFM ng 50/50%?

Any proper ways to dispose AFM regarding to environmental concern?

Would you recommend periodic cleaning of he media especially in the hydrotherapy market and wellness spa market where wellness treatments can clog the media. Hi from the UK fantastic series of presentations - Bish from SwimEx Aqua Thermae

Will there be an AFM ng 3 Grade?RegdrdsAndrey ECTES TD

Any expected lifelenght difference betwen AFM standard and AFM NG under equal conditions?

Thank you we use slight glass as standard for media inspection and at least 300mm clear pvc tube on the waste line - great

Good answer .. lol

But won't be around 20 years from now ..

My recent problem, less flow with AFM filtration, FRP tank dia. 21" with pipe dia 1", with Grade 3 x1sack lowest, Grade 2 x sacks, Grade 1 x 3sacks layers, with 1.5HP pump, which suppose to get 3m3/hr but resulted on 1.8m3/hr.

Is AFM applicable for liquid other than water. For example: Mono ethylene glycol (MEG)

correction from above: grade 2x 2sacks (middle layer)
