ANITA - Sidestream Nitrogen removal

Veolia Water Solutions & Technologies has developed the ANITA line of technologies for sidestream treatment: ANITA Mox ANITA Shunt

ANITA - Sidestream Nitrogen removal

Offering sustainable and cost-effective solutions, ANITA solutions are adapted to any advanced sludge treatment.

ANITA solutions contribute to the objective of an energy-neutral wastewater treatment plant while responding to more stringent regulation in terms of nitrogen concentration in treated water.

Based on the MBBR (Moving Bed Biofilm Reactor) technology, the ANITA Mox process is a sustainable and cost-effective solution to treat effluents highly loaded in ammonia.

The smart MBBR to treat high-ammonia effluents

The ANITA Mox solution combines an aerobic and an anoxic process into one Moving Bed Biofilm Reactor (MBBR), using both conventional nitrite producing bacteria and a specific Anammox biomass.
The high-ammonia effluent flows into a MBBR reactor filled with carriers which are kept in suspension by aeration and mixers.

A versatile range of use

With an ammonia removal efficiency of over 80%, ANITA Mox provides an efficient and sustainable answer to:

  • Treat liquid from advanced sludge treatment following
    > Abaerobic digestion
    > Thermal hydrolysis + anerobic digestion
    > Digestion of organic waste
  • Downstream polishing treatment for anaerobic treatment sytems
  • Treat leachate from waste landfills

ANITA 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

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

ANITA 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 sludfe composting or co-digestion platforms
  • Liquid from advanced sludge treatment following
    > Thermal drying
    > Hydrothermal oxidation
    > Thermal hydrolysis + anaerobic digestion
    > Anaerobic digestion
    > Digestion + lysis + digestion
