    Kitchen & Grease Trap

    Biological treatment for grease traps and kitchen drains, keeping pipes clear, reducing odour, and cutting maintenance costs.

    The Challenge

    Fats, oils, grease and organic residues accumulate in grease traps and drain systems. Left untreated, this leads to blockages, strong odour and rising operational costs.

    Grease build-up in drain pipe

    Common problems:

    • 1Rapid grease and sludge build-up in traps and pipework
    • 2Frequent blockages requiring emergency intervention
    • 3Persistent odour from anaerobic decomposition
    • 4High costs from frequent emptying and chemical additives

    These issues affect restaurants, canteens, catering facilities and any property with commercial kitchen drainage.

    Why grease traps alone are not enough

    Conventional grease traps capture floating fats, but they don't treat the wastewater. Over time:

    Dissolved and emulsified fats pass through untreated
    Sludge accumulates at the bottom, reducing trap capacity
    Anaerobic conditions create odour and corrosive gases

    The result: frequent pump-outs, chemical dosing, and systems that never reach stable operation.

    Biological treatment that works with your grease trap

    Biosep Nordic applies a biological approach based on bacterial spores and enzymes that actively break down fats and organic matter, continuously, not just at the point of emptying.

    Fat and oil degradation

    Probiotic microorganisms biologically break down fats, oils and organic residues over time, reducing uncontrolled accumulation in traps and drains.

    Enhanced microbial activity

    The treatment promotes healthy microbial activity inside the grease trap, outcompeting odour-producing bacteria and supporting continuous biological processing.

    Extended emptying intervals

    By reducing sludge and grease build-up biologically, the interval between pump-outs increases, lowering operational costs and maintenance burden.

    The treatment integrates directly into existing grease trap infrastructure. No modifications, no disruption to daily kitchen operations.

    Before & After

    The result

    Pipes and drains kept clear of blockages
    Sustained odour reduction at the source
    Longer intervals between grease trap emptying
    Lower maintenance and chemical costs
    Improved hygiene and operational reliability

    Biological fat degradation is a well-documented process. Results build progressively and depend on load, temperature and usage patterns.

    Tailored to your operation

    Biosep Nordic works with restaurant, kitchen responsibles and facility managers to assess wastewater conditions and recommend the right biological treatment approach, aligned with hygiene requirements and environmental compliance.
