Carbon Dosing

Carbon dosing assists the wastewater treatment process in two areas:

1. Denitrification

Where plants experience high levels of nitrogen in their discharged wastewater, carbon dosing can assist in reducing these nitrogen levels to help the plant achieve their EPA licence limits. Sucrosolutions™ has a COD level of 0.98kg/L, making it an attractive and effective form of carbon.

2. Healthy Biomass

Some wastewater treatment plants may experience a fluctuation in loads due to their location.  For example, industry off season, holiday resorts, ski fields can have extreme variations in their influent and volumes.  To ensure the bacteria are able to accommodate a sudden change in the composition of the influent, a carbon source can be used to maintain a healthy biomass.

Sucrose is a nutritive carbohydrate which assists in the denitrification process in wastewater treatment plants. For this process to occur the facultative heterotrophic bacteria that biologically reduce nitrate (NO3) to nitrogen gas (N2) require a carbon source to live.  This carbon source is readily available in the Sucrosolutions™ products D.Nitro™ and D.Nitro UV™.

The Sucrosolutions™ team can assist with modelling using sucrose as a carbon supplement.  Click here.

Running a trial is the best way to see how sucrose will perform in a wastewater treatment facility.   Each plant has a unique influent composition and microbial population.  A trial is usually run over six weeks and our Technical Manager is available to provide guidance on set up, data collection, monitoring and dosing advice.
