    Accelerated aging of the water body

    Accelerated aging of the water surface 1 1

    What you see

    Your aquatic ecosystem is showing signs of premature aging. The physical and biological indicators are mounting:

    • Bathymetry Reduction: The usable water column visibly decreases. The bottom rises each year, reducing storage volume.
    • Degraded Sedimentary Facies: Accumulation of a black, fluid (uncompacted) mud that releases gas at the slightest disturbance.
    • Thermal Modification: Water heats up faster and earlier in the season, promoting evaporation and the concentration of pollutants.
    • Centripetal Plant Colonization: Shoreline plants (helophytes) and submerged plants (hydrophytes like Water Primrose or Water Milfoil) gain ground towards the center of the body of water.
    • Organic Turbidity: The water loses its transparency, loaded with fine particles that no longer settle.

    What this means

    Naturally, a lake takes centuries to fill in. Here, TASO diagnoses a brutal acceleration of this process. The problem is simple: your body of water produces more organic waste than it is capable of cleaning.

    Three invisible mechanisms turn your pond into a swamp:

    1. Self-Silting (The Lake Fills Itself)
      Contrary to popular belief, silt does not always come from the shores, but from the water itself.
      The Mechanism: Algae and dead leaves sink to the bottom. Since the lake is “overflowing,” it can no longer process this material. It accumulates and forms organic silt that raises the lake bottom year after year.
      Result: The lake loses depth due to the accumulation of its own untreated waste.
    2. The Bottom Asphyxia (The Swelling Mud)
      The bottom of your body of water is no longer breathing.
      The Mechanism: Deprived of oxygen, the mud does not degrade properly: it rots (fermentation). This putrefaction produces gases that make the mud "swell" like a foam, increasing its volume and preventing its natural compaction.
      Result: A layer of soft mud, "puffed up" by gases, occupying a huge volume in the basin.
    3. Plant Colonization (The Light Trap)
      This is the final stage of the transformation.
      The Mechanism: As the bottom rises, the water becomes shallower. Sunlight can now reach the bottom in the center of the lake.
      Result: This signals plants (reeds, water lilies, water primrose) to take root everywhere, not just along the edges. Open water disappears.

    Conclusion: Your body of water is not dying of old age; it is suffering from organic indigestion. It stores matter instead of recycling it.

    Why act now?

    Accelerated aging leads to a tipping point beyond which gentle restoration becomes impossible:

    • Loss of Usable Volume: For rainwater harvesting or fire cisterns, the actual hydraulic capacity becomes insufficient for operation.
    • Irreversible Silting Risk: Once the root system of invasive plants has established throughout the bottom, only heavy mechanical dredging can reopen the environment. The cost is 10 to 50 times higher than biological treatment.
    • Biodiversity Collapse: The transformation into a hot, anoxic environment eliminates noble species (freshwater fish) in favor of resistant and invasive species.

    The TASO Solution
    Restore mineralization and oxidation

    The goal is to reverse the sediment balance by restoring the natural processes of material decomposition.

    1

    Sediment Oxidation and Structuring (Mineral Action)

    We modify the physical and chemical conditions at the bottom to stop fermentation.

    The action: The application of Nautex (Coccolithic Calcium Carbonate) acts directly at the heart of the sediment. It corrects acidity (pH) and reintroduces oxidizing potential.

    The result: The mud passes from an anaerobic state (fermentation, swelling) to an aerobic state. It mineralizes, compacts, and significantly loses volume.

    2

    Targeted Bioaugmentation (Material Digestion)

    We enhance the environment’s natural purification capacity by introducing specialized microorganisms.

    The action: The inoculation of selected bacteria (Biolimpid / Sludge Away) allows for the specific degradation of complex molecules (cellulose, lignin) that make up old organic sludge.

    The result: A physical reduction of the silt layer by transforming solid matter into water and inert gas. This is the principle of biological dredging.

    3

    Destratification and Oxygenation (Metabolic Support)

    We provide the conditions necessary for benthic bacterial life.

    The action: Installing a bottom aeration system (Oxylake) or hydraulic mixing homogenizes the water column. This ensures a constant supply of oxygen at the water/sediment interface, which is essential for maintaining digestion activity.
