Reliable process decisions begin with reliable measurements. That is why we are pleased to introduce Royce Aqua and its flagship portable instrument, the Royce Aqua 22.
Designed for water and wastewater treatment professionals, the Royce Aqua 22 combines total suspended solids measurement and sludge interface level analysis in one practical handheld system. It gives operators a convenient way to check mixed liquor suspended solids (MLSS), assess sludge blanket depth and record readings while working around a treatment site.
What Is the Royce Aqua 22?
The Royce Aqua 22 is a portable handheld MLSS and sludge blanket level meter for water treatment applications. It pairs an ergonomically designed analyser with a submersible sensor and 10-metre cable, allowing measurements to be taken at tanks, clarifiers and other process locations.
Unlike an instrument limited to a single measurement, the Aqua 22 has two operating modes.
TSS Mode
TSS mode measures total suspended solids in milligrams per litre. In activated sludge processes, this can support routine MLSS checks and help operators build a clearer picture of process conditions.
The instrument has a stated TSS measurement range of 0 to 20,000 mg/L.
Level Mode
Level mode is used for sludge interface layer analysis. As the sensor is lowered into a tank, the Aqua 22 displays the changing solids response together with depth, helping the operator identify the sludge blanket interface.
The integrated hydrostatic level sensor provides depth measurement over a range of up to 10 metres.
Why MLSS and Sludge Blanket Monitoring Matter
Solids concentration and sludge blanket depth are important indicators in many wastewater treatment processes. Regular checks can help operating teams understand settling behaviour, compare conditions across tanks and investigate changes before they become larger process issues.
A portable meter is especially useful when readings are required at several locations. Instead of relying on a fixed measurement point, operators can take the instrument to the process, gather readings where they are needed and retain a consistent record of the results.
The Aqua 22 is designed to make this routine work straightforward, from lowering the sensor and taking a reading to saving the result for later review.
Key Features of the Royce Aqua 22
Two Measurements in One Portable Instrument
The Aqua 22 supports both total suspended solids measurement and sludge interface level analysis. This gives water treatment teams one handheld platform for two common field measurement tasks.
Designed for One-Handed Field Operation
The lightweight analyser weighs approximately 320 g and incorporates a pistol grip. Rear trigger buttons initiate readings, while the front control cluster keeps the main operating functions within easy reach.
Clear Display in Changing Site Conditions
Large digits make live readings easy to see. The LCD is designed for clarity in bright sunlight, while a configurable backlight supports work in poorer lighting conditions.
Smart, Interchangeable Sensor Design
Calibration data is stored within the serialised sensor rather than the handheld unit. This allows a calibrated sensor to be connected to another compatible Aqua 22 handheld without requiring calibration simply because the analyser has changed.
Practical Data Recording
Readings can be saved to nine internal location records. The Aqua 22 also supports a microSD card for CSV data logging, allowing recorded results to be transferred for reporting or further analysis.
Built for Water Treatment Environments
The handheld analyser is rated IP65, while the sensor is rated IP68 for immersion during measurement. The sensor uses a polyurethane cable with an overall length of 10 metres.
How the Aqua 22 Supports Treatment Teams
The Royce Aqua 22 has been developed around practical site use. Its combination of portability, straightforward controls and two complementary measurement modes can support teams carrying out:
- Routine MLSS and TSS spot checks
- Sludge blanket depth surveys
- Comparisons between clarifiers or tanks
- Process investigations and troubleshooting
- Commissioning and maintenance checks
- Logged field measurements for operational records
With a stated accuracy of ±5% and repeatability of 1%, the Aqua 22 provides a consistent portable measurement tool when used, calibrated and maintained in accordance with the product manual.
Typical Applications for a Portable MLSS Meter
The Aqua 22 is suitable for a range of water and wastewater treatment environments where suspended solids or interface depth need to be checked at the point of use.
Typical applications may include:
- Activated sludge and aeration processes
- Final and secondary settlement tanks
- Clarifiers and thickeners
- Sludge holding tanks
- Industrial effluent treatment
- Process surveys across multiple measurement locations
The exact measurement procedure and calibration should always be matched to the process and tank being assessed.
A Practical New Option for Portable Solids Measurement
Royce Aqua brings together robust sensing, field-focused design and straightforward data capture.
At the centre of the range, the Aqua 22 gives treatment professionals a portable way to measure TSS and MLSS, locate the sludge interface and retain useful site records using a single instrument.
For teams looking to improve routine solids monitoring without adding unnecessary complexity, the Royce Aqua 22 offers a focused and practical solution.
Frequently Asked Questions About the Royce Aqua 22
What Does the Royce Aqua 22 Measure?
The Aqua 22 has two operating modes. TSS mode measures total suspended solids in mg/L, while Level mode supports sludge interface layer analysis and displays the measured depth.
Can the Aqua 22 Be Used as a Portable MLSS Meter?
Yes. Its TSS measurement mode can be used for portable mixed liquor suspended solids checks when the sensor has been correctly calibrated for the process.
What Is the TSS Measurement Range?
The stated TSS measurement range is 0 to 20,000 mg/L.
What Depth Can the Sensor Measure?
The Aqua 22 has a stated depth range of up to 10 metres and is supplied with a 10-metre sensor cable.
Can Readings Be Saved?
Yes. Readings can be saved against nine internal locations. Data can also be logged to a compatible microSD card in CSV format.
Is the Sensor Submersible?
The sensor is rated IP68 and is designed to be immersed when taking a measurement. The handheld analyser is rated IP65 and must not be submerged.
