ANITA™ Shunt

ANITA™ Shunt

ANITATM Shunt is an innovative technology to eliminate ammonia in highly-loaded effluents while meeting environmental objectives in terms of carbon footprint reduction.

The smart SBR to treat high-ammonia effluents

ANITATM Shunt is ideal for plant upgrades or installations where a simple solution for increased nitrogen removal is required.

ANITATM Shunt uses a traditional activated sludge and a sequential Batch Reactor (SBR) to stop nitrogen oxidation at the nitrate stage (NO2-) and to reduce the quantity of biological sludge produced.
The process is designed to treat highly-loaded effluents with a N-NH4 concentration of over 100 mg N/l.

A versatile range of use

  • Biological treatment coupled with anaerobic digestion using methanol during post-denitrification
  • Leachate from sludge composting or co-digestion platforms
  • Liquid from advanced sludge treatment following
    > Thermal drying
    > Hydrothermal oxidation
    > Thermal hydrolysis + anaerobic digestion
    > Anaerobic digestion
    > Digestion + lysis + digestion
