Portable Sludge Blanket Depth Testing
Locate the sludge-water interface in clarifiers and treatment tanks with a portable instrument designed for tank-side depth checks.
What does sludge blanket depth show?
Sludge blanket depth identifies the interface between settled sludge and clearer water above it. Routine portable checks help operators understand clarifier behaviour, compare tanks and identify changes before solids carryover becomes visible in final effluent.

Where portable sludge blanket depth testing is useful
Portable instruments for sludge blanket depth
The correct instrument depends on the measurement method, expected range, water matrix, other parameters and how results need to be recorded.
Royce Aqua 22
Uses a hydrostatic sensor to identify sludge blanket interface depth from 0 to 10 m and also measures MLSS/TSS by infrared absorption.
Best for: operators needing depth and suspended-solids information from one portable instrument.

Portable sludge blanket depth testing FAQs
What does portable sludge blanket depth testing show?
Sludge blanket depth identifies the interface between settled sludge and clearer water above it. Routine portable checks help operators understand clarifier behaviour, compare tanks and identify changes before solids carryover becomes visible in final effluent.
Where is portable sludge blanket depth testing useful?
Common uses include secondary clarifier blanket checks, sequencing batch reactor monitoring, tank-to-tank process comparison, return and waste sludge decisions. The best sampling point should always be chosen around the decision the result needs to support.
Which portable instrument can measure sludge blanket depth?
Royce Aqua 22 is the current Portable Analyser option shown for this parameter. Its suitability still depends on the method, range and sample.
Can a portable result help verify an online analyser?
Yes. A carefully collected portable result can provide an independent spot check during commissioning or investigation. Sampling location, timing, preparation and method differences must be considered before comparing readings.
What information should I provide before requesting a quote?
Share the water type, expected range, sampling location, testing frequency, other required parameters, record-keeping needs and any site constraints. This helps PMA confirm the complete practical package.
Can PMA help select the correct method and equipment?
Yes. PMA can review the application, expected conditions, measurement method, reagents or sensors, calibration needs and supporting accessories before quotation.
