    turbid water, suspended solids 1 1

    What you see

    The water appears cloudy, grayish, brownish (earth-colored), or milky.

    Fine particles remain suspended in the water at all times. Even after a week without wind or rain, the water does not clear up.

    Transparency is virtually nonexistent, regardless of the amount of sunlight.

    Unlike algae blooms that occur in the summer, this problem can persist year-round, including in the winter.

    What this means

    This type of problem is primarily physical rather than biological. It indicates a high concentration of suspended solids (SS) in the water column.

    These materials may include:

    • of mineral origin: fine clays, silts, particles resulting from the erosion of soil or riverbanks,
    • of organic origin: plant debris, excrement, decomposing matter, biofilm.

    In many cases, water exists in a colloidal state. The very fine particles carry a similar electrical charge and repel one another, preventing any natural settling.
    They thus remain in permanent suspension, keeping the water cloudy.

    When the organic fraction is dominant, this condition also indicates insufficient microbial activity: the natural breakdown of organic matter can no longer keep pace with the amount being produced.

    This profile is common in water bodies subject to high organic loading, low water circulation, or regular erosion.

    Why act now?

    Over time, persistently cloudy water can lead to:

    • A reduction in light penetration, as photosynthesis is necessary for maintaining a healthy balance of biological parameters in the water.
    • Respiratory stress in fish, as certain particles can accumulate on the gills.
    • An increase in sedimentation, with particles eventually accumulating at the bottom.
    • A deteriorated appearance, and in the case of swimming areas, this can prevent them from opening due to visibility concerns.

    The TASO Solution
    mineral clarification & biological activity

    Colloidal suspended solids are not removed by simple filtration.
The process involves directly modifying the structure of the particles and the organic load.

    1

    Mineral flocculation (Physicochemical process)

    The controlled addition of calcium carbonate (Nautex) alters the electrical charge of the particles.
    They aggregate into heavier flocs that naturally settle to the bottom.
This step allows for a rapid return to clear water, promoting better oxygenation and photosynthesis in the water body.

    2

    Biological digestion (Microbiological action)

    When suspended solids contain a significant organic fraction, the introduction of specific microbial complexes helps accelerate the mineralization of the deposits.
    This process limits the conversion of flocs into fermentable sludge and provides long-term stabilization of water quality.

    3

    Bottom aeration (Mechanical action)

    Oxygenation supports bacterial activity and limits the resuspension of particles caused by bottom fermentation.
    It provides long-lasting clarity, increases photosynthesis, and improves water oxygenation to balance water parameters and promote aerobic microbial life.
