  • Foaming during anaerobic digestion: Causes and Solutions

    Foaming during sludge treatment has traditionally been associated with activated sludge systems which have been victim to this phenomenon for several decades. However, foaming has been documented in anaerobic digestion plants, leading, fundamentally, to a reduction in digester capacity and an increase in operational expenditure. The requirements for foaming of: surface active agents, gaseous ...

  • Addressing food waste through anaerobic digestion

    Food waste continues to be a problem worldwide, even with more and more attention being paid to reducing spoilage and to salvaging edible foods for redistribution or reuse. One approach to the problem is diverting inedible organic matter from landfills and treating it with anaerobic digestion, which has the side effect of capturing energy. The amount of food wasted worldwide was 2.3 billion ...

  • Peristaltic Pumps excel in Anaerobic Digestion & Biogas applications

    Biogas is a natural gas also known as biofuel or biomass and is produced by breaking down organic material such as household waste, manure and crops grown specifically for biofuel with temperature-sensitive microbes and capturing the by-products. In practice, it is difficult to find a pumping system for this application. Why? The pumps needs to handle fluid media as well as gas parts ...

  • Nitrogen removal from digested manure in a simple one-stage process

    A process based on partial nitrification and recirculation into the anaerobic digester was studied to remove nitrogen from digested manure and thus reduce enhanced gaseous ammonia emissions due to on-farm biogas production. An anaerobic reactor representing an anaerobic manure digester was fed with a nitrite solution and digested manure liquor. Nitrite was efficiently removed from the influent ...

  • Anaerobic Digestion Reduces Microplastics in Sludge

    Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and personal care products, including toothpaste, cosmetics, and beauty scrubs. They also include fragments from the breakdown of anything in our ...

  • Application of acidic thermal treatment for one- and two-stage anaerobic digestion of sewage sludge

    The effectiveness of acidic thermal treatment (ATT) was examined in a 106-day continuous experiment, when applied to one- or two-stage anaerobic digestion of sewage sludge (4.3% TS). The ATT was performed at 170°C and pH 5 for 1 hour (sulfuric acid for lowering pH). The one-stage process was mesophilic at 20 days hydraulic retention time (HRT), and incorporated the ATT as pre-treatment. The ...

  • Anaerobic Co-Digestion of a Single Source Oily Waste and High Strength Pet Food Wastewater: A Study of Failure and Revival of a Full Scale Digester

    ABSTRACTThis paper focuses on the revival of a formerly failed digester of 1800 m3 volume. The most obvious cause of failure was identified to be due to capping caused by foam and scum, as result of attempting to treat oil rich, high strength wastewater. The revival was affected by implementing co-digestion in a 3-step remedial procedure. Though in the typical sense, codigestion involves separate ...

  • What is energy recovery?

    Processes like incineration and anaerobic digestion not only provide sources of energy, but they also reduce waste volume The term “energy recovery” often is applied only to a narrow number of methods for converting wastes into energy, when in fact it applies to a broad range of technologies used to create heat, electricity, or fuel. Energy recovery gives ...

  • Adding Value With Anaerobic Digestion

    Adding waste-to-energy technology to wastewater treatment produces energy that can be used to power operations Anaerobic digestion (AD) is a biological process that uses microbes to biodegrade organic matter (feedstock) in the absence of oxygen. It provides a host of benefits in the treatment of challenging wastewater streams while offering the opportunity to produce value in the ...

  • Are incineration and landfills the answer to save us from the recycling crisis?

    For plastic recycling, this year hasn’t exactly been one of the best – what is to blame? Oil. Shockingly, it actually costs more to recycle old plastic than it does to make new in many ways. Petroleum prices have fallen so low, as low as 70% below the level in June 2014. This may be great for some – however with it has fallen the cost of Virgin Plastic which is made from ...
