Sponge iron is a potential material for nitrogen and phosphate removal. To explore the performances and mechanisms of nitrogen and phosphate removal by sponge iron, a sponge iron biofilter was established. The results showed that nitrate was completely removed at HRT of 48 h without external carbon source and at HRT of 3 h with C/N ratio of 5.

Lead / Tin Solder - wiping process does not cool the soldering iron tip - gentle abrasive property gives superior cleaning of residual solder - molten solder readily forms globules on the sponge that fall away - no stresses to soldering iron from cold shock – prolongs tip life - no wet acid residues remain on dry sponge so tips are not eroded RoHS Directive Lead Free Solder – as above but ...
