Dry solids in Iron Sludge & 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 ?

OEM Solutions

The OLPAS Technology and hardware are used as independent sensors (under the Olpas brand or other brands) and as part of other applications. Together with your product-development team we develop an OEM solution that is optimised for your application.

Sludge Dewatering

We provide sensors for a complete insight into (sludge) dewatering. We measure dry solids in sludge, residual polymer and TSS in centrate, and high solids concentrations (eg. in the dry cake) or in iron water.
