FAQs
What does 'Suspended Solids' mean?
Suspended solids are particles suspended in water. They occur naturally and can be seen for example in rivers after a rainfall event when the river appears ‘muddy’.
Why should I measure Suspended Solids?
Treating water and wastewater has two main focuses: the removal of organics and particles, and then disinfection. Having information about the level of suspended solids can be invaluable in informing treatment processes (such as tracking changes in suspended solids in raw water entering a drinking water plant or monitoring the efficacy wastewater at the outlet), and so these kinds of sensors are very common in many industries and applications.
What unit of measurement is preferred when measuring Suspended Solids?
Suspended solids are generally measured in mg/l. Sometimes, if they are present in large amounts, a percentage is used or g/l.
What is the difference between Suspended Solids and Turbidity?
Suspended solids and turbidity are measured differently, but they are related. Suspended solids measurements are based on the mass of solids present in a certain volume of water (mg/l), whereas turbidity is measuring how ‘cloudy’ it is in NTU. A common conversion used is 1mg/l = 2 NTU, but different suspended materials can have a different relationship.
Is there a maximum level of solids that can be measured by the SoliSense®?
The qualities of the process water and the solids to be measured will affect the effective maximum level that can be measured. For a ‘clean’ application (such as silica in clean water), we could expect to be able to measure up to 50% solids (500,000 mg/l) reliably. On the opposite side of the spectrum, black sludge in a wastewater plant may have a reliable limit as low as 5% (50,000 mg/l). Experience shows that in most wastewater works the upper limit is around 8% solids (80,000 mg/l).
