    Digester Additives

    Every biogas plant is unique, but very rarely will one run at full efficiency without the intervention of process additives. FM BioEnergy has a range of products to cover all potential issues you may encounter while operating a digester. These include:

    Important Process Parameters

    To run an efficient biogas process the operator needs to monitor and control the biological process. Some parameters are controlled by the plant design, while others need careful feedstock selection or additves.

    “Six months after suffering a biological failure, our plant was back running at its highest levels of electrical output ever, thanks to biological support from FM BioEnergy. It is now running at 100%.”
    Ben Jenkinson, Generation X

    "A 1 MWe plant running at 70% efficiency is losing a potential income of £1,000 per day, even before you factor in feedstock costs. If the cause of inefficiency is due to biological reasons, the situation will only improve with intervention.”
    Tim Elsome, General Manager, FM BioEnergy

      Trace Elements

      Bespoke, highly bioavailable and in both in granular and liquid form

      If a plant is lacking in vital trace elements, it will yield less gas and suffer process disruption, resulting in reduced profit for the operator. Through our sophisticated laboratory analysis and easy-to-interpret results, we can determine whether your plant is nutritionally deficient and prescribe the right trace element formula to get it back to full health – and keep it there.

      H2S Control

      Many feedstocks produce high levels of hydrogen sulphide (H2S) in the digester, which is detrimental to the AD process. This can be partially managed by injecting O2 into the digester headspace, but brings the risk of technical problems in the future. The most effective way to manage H2S levels is through the addition of iron. With a unique formulation, our product, ATOX.Scon, contains the optimal iron content to ensure the best possible control of H2S in your digester.

      Ammonia Control

      For many plants, high nitrogen feedstocks deliver a cost-effective biogas output. However, nitrogen breaks down into ammonium and ammonia; the latter being toxic to bacteria. Left untreated, this is detrimental to the AD process. If you’re processing nitrogen-rich feedstocks such as food waste or chicken litter, our ammonium binder, ATOX.Ncon, will ensure you get the best out of your substrate and prevent acids from building up.

      Enzymes for increased biogas and reduced viscosity

      Just as our bodies need enzymes to break down the food we eat, so the microbes in a digester need help to break down fibrous feedstocks, such as grass, maize or wholecrop rye. Adding the right enzymes exposes the cell membrane, speeding up the digestion process, improving gas yields, reducing viscosity and providing theoretical retention time.
