Sewage Sludge
High amounts of sewage sludge are produced as a result of unavoidable human activities and the volume has become a social and environmental issue. Anaerobic digestion and/or composting of sewage sludge are technologies that have been shown to effectively address many of the problems associated with waste and manure management, with the additional benefit of providing a reliable energy resource.
Nutrients found in sewage sludge come in both organic and inorganic forms. Inorganic nutrients, mostly ammonium (NH4+) and nitrate (NO3-), are readily available to plants. Before organic nutrients can be taken up, however, they must first be converted to inorganic forms. This process, which is completed by soil microbes as a by-product of organic matter breakdown, is called decomposition. The decomposition rate is, therefore, the rate at which organic nutrients are made plant available.
An understanding of the concept and rate of decomposition can help improve manure management to meet crop nutrient demands while minimizing the potential for regulatory concerns regarding groundwater pollution.
The BioCRUDE Advantage
The added BioCRUDE reactant and/or fungal technology (enzymes) in conjunction with its processes, extends the range of degradable substrates. This leads to a lower viscosity with improved separation and a decreased application of flocculent. Besides that, there is a higher output of digester gas (up to 25 % more). The result is the improved profitability of a sewage sludge plant.
