[Greenbuilding] surface area

[Stephen]

Pumice? Some floats, maybe sinks after a while. Lots of surface area.

  in our region, recycled, crushed concrete is available in several popular
grades.  not very lightweight, but I   imagine the surface would be
microbe friendly.

this does however, raise the question of PH, due   to the alkaline nature
of portland.

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

      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?
