Wastewater-treatment monitoring across the liquid and sludge streams. The instruments below follow the application groups in the original Thermo Scientific solution diagram.
- Wastewater inlet → equalisation → primary settling
- Aeration → secondary settling → nitrification
- Final filtration → disinfection → discharge
- Return activated sludge → aeration
- Waste activated sludge → gravity thickening → aerobic/anaerobic digestion → dewatering → separation → sludge disposal
Wastewater inlet
3106COD automatic chemical oxygen demand monitor; 3150TPN total phosphorus/total nitrogen monitor; 2240 ammonia-nitrogen monitor; AquaPH differential pH; AquaSol suspended solids/sludge concentration.
Equalisation
AquaPH differential pH; AquaRDO optical, membrane-free dissolved oxygen.
Primary settling
AquaSol suspended solids/sludge concentration.
Aeration
AquaPH differential pH; AquaRDO optical, membrane-free dissolved oxygen; AquaDO polarographic dissolved oxygen; AquaORP differential oxidation-reduction potential; AquaSol suspended solids/sludge concentration.
Secondary settling
AquaSol suspended solids/sludge concentration; AquaPH differential pH.
Nitrification
AquaRDO optical, membrane-free dissolved oxygen; AquaDO polarographic dissolved oxygen; AquaPH differential pH; AquaSol suspended solids/sludge concentration.
Disinfection
Chlorine XP residual/total chlorine; AquaOZ dissolved ozone.
Discharge
3106COD chemical oxygen demand; 3150TPN total phosphorus/total nitrogen; 2240 ammonia-nitrogen; AquaPH differential pH; AquaTurb high-range turbidity.
Aerobic / anaerobic digestion
AquaRDO optical, membrane-free dissolved oxygen; AquaDO polarographic dissolved oxygen; AquaORP differential oxidation-reduction potential; AquaPH differential pH; AquaSol suspended solids/sludge concentration.
Waste activated sludge and disposal
AquaSol suspended solids/sludge concentration monitors the waste activated sludge. AquaPH differential pH is specified for sludge disposal.
