FLOCMARK®

Computer vision analysis of biosludge images.

Biosludge structure analysis

The control of biosludge structural quality is in high importance for efficient wastewater treatment performance. With well-operated biological treatment that support strong biosludge floc formation, the effluent quality can be significantly improved.

Computer vision application Flocmark® is built to analyse biosludge structure from microscopic images. It gives process engineers, lab specialists, and plant operators the ability to see deeper, respond faster, and manage biological treatment with confidence.


Flocmark® has been field-tested across a range of industries, including pulp, paper and board manufacturing, municipal wastewater treatment, and oil refining. With its easy-to-use web interface, Flocmark® blends seamlessly into existing laboratory routines, making advanced image analysis part of daily workflow.​

Upload and analyse

Biosludge images are uploaded to Flocmark® with web browser. Computer vision analysis is started with a simple click and results are displayed in user interface.


Image analysis covers the whole biosludge structure, including flocs, filaments and fine particles. More information of floc development is provided with floc size and porosity distributions.


Images are collected and saved in user archive, where historical samples and their data are easily accessible and can be compared to each other.

See results instantly

Analysis results are displayed as diagrams  and numeric values. Sample comparison in the user interface allows users to compare biosludge structures and image data across samples.


Structural changes are often seen through visual interpretation and numeric comparison. Early indicators may appear only in data, making computer vision analysis a valuable addition to user interpretation of sludge quality.

Follow trends over time

Biosludge structural development over time is best seen with trend categories providing information on floc formation, filament amount, and fine particles occurrence.


Good structural quality is often seen as low number of filaments and fine particles, high floc size, and low floc porosity.


For all parameters, user can define target areas and objectives. If a parameter is out of target, Flocmark® can raise predictive flags for early warnings indicating signs of process distress.

Export and share

Export raw data as an Excel spreadsheet for further statistical work or data merging. For communication, generate a clean PDF report containing both numeric and visual summaries of your sample.


Whether it’s compliance, reporting, or team briefings — Flocmark® insights are ready to share instantly.
