    Filter Clogging & Blockage

    Filter clogging 1 1

    What you see

    Your filtration or pumping system is experiencing unexpected shutdowns and drops in performance. The technical symptoms are clear:

    • Rapid filter clogging: Your sand, screen, or disc filters show a high differential pressure just a few minutes after being cleaned.
    • Clogged emitters: In irrigation systems (drip irrigation, sprinklers), the nozzles become clogged, creating dry spots on your crops or your green.
    • Biological slime: When disassembling the unit, you will find a brown or green gelatinous substance (known as “biofouling”) that sticks to the walls and filter media.
    • Pump Safety: Clogged suction strainers can cause cavitation or frequent air locks.

    What this means

    This is not a problem with the filter size, but rather a problem with the incoming biological load. The pumped water contains invisible particles that clump together once they enter the system:

    • Biofilm (biofouling): This is the main cause. Bacteria secrete a sticky mucus (polymers) that coats the inside of pipes and filters. This mucus traps all mineral particles.
    • Microalgae and Zooplankton: Even if the water looks clear, it can contain thousands of algae cells per milliliter. Under pressure from the filter, they form a compact, impermeable mat.
    • Matières Colloïdales : Des particules fines en suspension (argiles, limons) chargées électriquement qui ne décantent pas et saturent les médias filtrants fins (< 100 microns).

    Why act now?

    Fouling isn’t just a maintenance issue; it’s a major operational risk:

    • Loss of yield (Agricultural/Golf): Uneven irrigation caused by clogged nozzles leads to crop loss or the death of the turf (dry patches).
    • Additional energy costs: A pump that has to work harder to push water through a clogged filter consumes up to 40% more electricity.
    • Equipment wear: Repeated backwash cycles cause premature wear on valves and mechanical seals.
    • Health risk: Biofilm in pipes provides an ideal haven for pathogenic bacteria (Legionella, E. coli), which are protected from conventional disinfectants.
    • Accelerated/faster disease spread: Microorganisms circulating in a clogged system can be redistributed during irrigation, leading to rapid contamination of crops, lawns, or sensitive areas.

    The TASO Solution
    Deconstruct upstream to protect downstream

    TASO protects your equipment by treating the water before it enters the pipe. Our strategy: preventing biofouling.

    1

    Ultrasonic Protection (Anti-fouling Effect)

    We install ultrasonic emitters near the water intake.

    How it works: Acoustic vibrations prevent bacteria and algae from attaching to surfaces and forming biofilm. The material remains in "free" suspension and passes through coarse filters without sticking, or is easily flushed away during rinsing.

    2

    Enzymatic and bacterial digestion (Active cleaning)

    We inject specific bacteria (Biolimpid) capable of breaking down the organic matrix (mucus).

    The process: The binder that holds the particles together is removed. The filters now retain only the mineral, which is much easier to clean by simply backwashing.

    3

    Mineral Flocculation (Filtration Optimization)

    If the problem is caused by fine particles (clay), adding Nautex helps flocculate them to the bottom of the pool rather than into your filters.
