BIOFLOC-N (Ammonic Nitrogen Eliminator)
● BIOFLOC-N ?
- BIOFLOC-N is a non-toxic and bio-degradable environmental friendly microbiological polymer coagulant which can show excellent effect in the elimination of suspending substances and ammoniac nitrogen within waste water.
- BIOFLOC-N is a mixed type coagulant using salts and polysaccharide, a biogenic polymer. This product removes total nitrogen within waste water by inducing crystallization of ammoniac nitrogen.
- BIOFLOC-N is a bio-degradable and non-toxic coagulant. This product has no secondary contamination of surplus sludge and is available as a fertilizer.
- BIOFLOC-N is convenient since this product can be used the same way as the existing inoculum agent in an aeration tank and then does not need the additional processing facility.
- BIOFLOC-N is a newly developed product enabling to reduce total nitrogen concentration from 60ppm to below 20ppm for Specially Controlled Area and below 60ppm for remaining regions starting from 2002.
