What is sintered glass?
If you melt (sinter) very small glass balls, a massive lump of glass comes out. But if you mix the glass beads with salt beforehand, the resulting glass lump is permeated with salt. If it is then washed out, an infinite number of small channels are created in the glass. JBL sintered glass filter materials therefore contain a gigantic (inner) surface area which can be colonised by bacteria which in turn break down harmful substances.
Nitrate is only decomposed by bacteria to nitrogen gas in the absence of oxygen and in the presence of carbon (C). This process (denitrification) can take place under ideal conditions inside the sintered glass filter materials JBL SintoMec and JBL MicroMec.
When to use JBL MicroMec and when to use JBL SintoMec?
For smaller filter volumes, the smaller material JBL MicroMec is more suitable for reasons of space. For larger filters, also because of the greater water flow, a coarser material with holes such as JBL SintoMec is more suitable. The finer JBL MicroMec could clog up more quickly.
