    ’s biological expertise serving water bodies

    For 40 years, TASO has been helping local governments, tourist attractions, farms, and industrial sites with the sustainable restoration of their ponds and bodies of water.

    Our approach is based on bioremediation: a scientific method that works with the environment’s natural processes to restore stable, resilient, and measurable functionality. While chemical treatments often provide only temporary relief, TASO addresses the root causes of imbalances to ensure lasting results.

    Our mission: to restore
    the balance of aquatic ecosystems

    Every body of water is a living ecosystem. When it becomes unbalanced, it’s never just one factor; it’s the entire system that goes awry.

    Our work aims to restore:

    • the natural ability to self-regulate and self-purify,
    • the biological, mineral, and bacterial balance,
    • the overall quality of the water body's ecosystem.

    's comprehensive and multidisciplinary approach

    To ensure lasting results, TASO relies on three complementary pillars:

    scientific expertise

    Scientific expertise

    Upon request, we conduct comprehensive assessments, including: physicochemical analyses, water column measurements
    , nutrient dynamics (nitrogen/phosphorus), sediment condition, and identification of biological imbalances.

    field experience

    Field experience

    With over 40 years of experience working in France and across Europe, our teams are well-versed in operational challenges. Each protocol is tailored to the specific site, taking into account factors such as climate, depth, water flow, intended uses, and objectives.

    systemic reading

    A systemic analysis of the environment

    We take a holistic approach: internal circulation, stagnant areas, ecological blockages, nutrient flows, and the “memory” of the water body.
    This approach enhances the effectiveness of treatments by addressing the entire system, not just a single symptom.

    Restoring a body of water is not simply a matter of adjusting a single parameter.
    It involves understanding its history, its dynamics, and its internal logic.

    's technological innovation serving life sciences

    To address climate challenges and operational constraints, we implement eco-friendly, non-invasive solutions that are compatible with local flora and fauna.

    Mineral Balance

    Mineral rebalancing forms the basis of many TASO protocols.
The addition of naturally sourced calcium helps maintain the physical and chemical balance of the environment, promotes sediment oxidation, stabilizes pH, and sustainably improves water clarity.

    Our products

    Bioremediation

    Bioremediation aims to reactivate the natural biological processes in a body of water using selected microorganisms. This gradual approach addresses organic and nutrient imbalances without disrupting the ecosystem.

    • Biolimpid: Gradual reduction of sludge through the mineralization of organic matter
    • Algibio: Controlling filamentous algae through biological competition
    • Cyanocline Control: Control of Cyanobacteria and Green Water Phenomena
    Our products

    Ultrasonic Technology

    A technology that controls algae and cyanobacteria without the use of harsh chemicals. The acoustic emissions target the cellular structure of the algae, reduce their buoyancy, and promote their settling.

    Our products

    Controlled oxygenation

    Oxygenation is a key factor in the functioning of water bodies.
Effective management of dissolved oxygen helps to revitalize natural biological processes and sustainably stabilize water quality:

    • improved transparency,
    • more stable physicochemical parameters,
    • strengthening of self-purification mechanisms

    Is the water quality in your pond deteriorating?
Avoid taking the wrong steps. A diagnostic assessment can help identify the causes and establish an effective plan of action.
