    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 acts on the natural mechanisms of the environment to restore stable, resilient, and measurable functioning. Where chemical treatments often provide a temporary effect, TASO addresses the causes of imbalances to secure results over time.

    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.

    An approach
    comprehensive and multidisciplinary

    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.

    Laurent Pierre Castagnera, Director of TASO

    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 : progressive reduction of sludge by mineralization of organic matter
    • ALGIBIO : limitation of filamentous algae by biological competition
    • Cyanocline control : control of cyanobacteria and green water phenomena
    Our products
    Ultrasonic Technology

    A technology for limiting algae and cyanobacteria without resorting to aggressive chemistry. Acoustic emissions target the cellular structure of algae, reduce their buoyancy, and promote their sedimentation.

    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.
