The patented technology in the SoliSense
® means that a single sensor can cover a very large range. This means that you don’t need to have so many different sensors across a water treatment works (WTW) or wastewater treatment works (WWTW). This in turn means;
- Less spares – need to be held across one or more plants
- No requirement to know the range before ordering – easier purchasing
- One online suspended solids analyzer can be an:
- MLSS meter
- TSS meter
- Online total suspended solids meter
- Online effluent monitor
- Online inlet monitor
- Online ‘in process’ suspended solids analyzer
The SoliSense® has been designed to be suitable for all suspended solids monitoring applications in both water treatment works and wastewater works including:
- Inlet monitoring (turbidity 2-4,000 NTU)
- Effluent monitoring (suspended solids 0-1,000 mg/l)
- Online suspended solids analyzer
- Online RAS meter (Return Activated Sludge)
- Online MLSS meter (Mixed Liquor Suspended Solids)
- Online WAS meter (Waste Activated Sludge)
- Thickened sludge – Online total suspended solids meter
- Centrate – Online total suspended solids meter
- Filtrate – Online total suspended solids meter
- Backwash water – For control of filter backwashing on a water treatment plant
- Wastewater effluent – Online total suspended solids meter
- Wastewater influent – Online total suspended solids meter
The SoliSense
® suspended solids sensor can come with several installation options including;
- Dip – where the sensor is mounted on the end of a pole that dips it into a tank or open body of water
- Insertion – where the sensor is inserted into a pipe through a special ball valve that allows the sensor to be removed while still under pressure
- Flow cell – where the sensor is mounted in a specialist flow cell and the sample flows through it.

Each sensor has an LED light source that emits in the infra-red and has a working lifetime of 15 years. Each suspended solids sensor has two detectors.
The light emitted is detected by the emitter detector. That light then goes through the sapphire optical windows and into the sample. With refraction and reflection, some light comes back into the sensor to the detector, which is at 120 degrees to the emitted light, and the ratio of the emitted light to the received light is proportional to the suspended solids in the sample. By varying the amount of light that is outputting the sensor can correct for effects introduced by, for example, the optical properties of the windows or aging optics or drifting electronics (all electronics drift). It is this technique that has been patented and provides for the stability and range of the SoliSense®.
The electronics provide a fully scalable output allowing the SoliSense® to measure any part, or the whole, of the scale. The sensor probe comes equipped with the capability of having a water jet regularly sweep over the optical lenses keeping them clean. If you have an application that ranges from low NTU all the way to %age solids then the SoliSense® is certainly the suspended solids monitor for you! With up to 5 calibration points you can accurately monitor your process across a wide range of sample concentrations.
The probes are constructed of 316 stainless steel with sapphire optical windows, so can withstand demanding operating environments.
By using two detectors in a single probe it is possible to:
- Measure turbidity from 2 NTU to 4,000 NTU
- Measure solids from 0.001 to 80 g/l (8% solids) – Sludge
- Measure solids from 0.001 to 500 g/l (50% solids) – Silicates
