[Greenbuilding] surface area

[John Salmen]

Hi

Your talking about a biofilter and foam chips have been used successfully
for that in all types of wastewater treatment for maintaining a 'smutzdecke'
(waterloo biofilter is one example) though typically it is graded sand and
gravel. Netted bags of foam chips with some kind of ballast might work well.
Lots of research out there.

 

Best

John

Subject: [Greenbuilding] surface area

 

I am building a natural pool and could use some insight into the media used
in the regenerative zone.

Typically gravel is used since it creates large surface area for microbes
and lasts.

Ideally I would prefer something lighter so it can be more easily removed
when the pool leaks.

I considered crushed brick but dust could be an issue.

I salvaged some Spanish S tile I could put in and cover with gravel. I
wouldn't break it I would just put it in the way it comes stacked on the
pallet. Any thoughts on how that would compare to gravel in terms of surface
area? Keep in mind that microbe surface area is different than surface area
we can see.

Using safety netting from job sites would have amazing surface area but I am
not interested in the leeching possibilities.

 

Any thoughts?
