Dry solids in Iron Sludge and Iron Slurry
Knowledge of the Dry Solids concentration (DS%) is important for an economic and environmental management of iron sludge or iron water.
It gives an indication of the performance of the dewatering process and can be used to optimise transport and economic & environmental impact.
Online monitoring the dry solids concentration, allows to optimise the dewatering process and to minimise unnecessary transports of low concentration iron water.
Iron sludge/slurry, also known as iron oxide sludge or ferric sludge, is a byproduct of drinking water production from water that contains iron.
Iron sludge forms when iron compounds are precipitated during water treatment processes for production of drinking water.
The management of iron sludge can be a challenge as it requires proper handling and disposal to prevent environmental contamination. Common methods for managing iron sludge include dewatering or drying to reduce its volume before recycling or reuse in certain applications.
How do Olpas sensors compare to traditional sensors ?
Optical (UV) | Microwave | Olpas Sensors | |
Unaffected by colour variations? | ❌ | ✅ | ✅ |
Applicable in high turbidity medium? | ❌ | ✅ | ✅ |
Unaffected by signal reflection of iron particles? | ✅ | ❌ | ✅ |
Maintenance interval required | x2 per week | x1 per month | x1 per season |
Measurement of iron sludge is very challenging with traditional measurement technologies.
