Evogen Bioblocks have been specially formulated to be used as controlled release technology in wastewater treatment systems to boost performance, by improving effluent, odour and sludge parameters. Bacillus capable of floc formation are slowly released into a system to help tackle problems associated with organic compounds such as FOG and excess BOD/COD.
How it works
As the block is exposed to effluent, the bacteria within the structure are conditioned to the effluent characteristics and when released they have no need for a prolonged acclimation phase. This allows the Bacillus microbes to immediately begin augmenting the system by delivering their metabolic activity to digest materials such as FOG, proteins, DNA, plant materials and various other polymeric substances.
Rather than using a carrier to induce floc formation, the Bacillus within the product have been selected due to their unique ability to form flocs on their own. These flocs, which typically have a Sludge Volume Index (SVI) of <100, are well suited for the activated sludge system offering compact structures with excellent settling properties.
The use of several Bacillus species which grow synergistically provide a consortium that are not only metabolically diverse but capable of performing over a range of temperature and pH ranges. With good growth rates under both high strength industrial type effluents and lower strength municipal wastewaters, Evogen Bioblocks give the operator a versatile technology to tackle a multitude of scenarios at both large and small treatment works.
Through investigations into the genomic profiles of our Bacillus we are able to tailor both extracellular enzymes and secondary metabolite profiles to provide a product with robust metabolic capabilities.
For example; through the secretion of several different biosurfactants (which are far more powerful than chemical equivalents) our Bacillus are able to effectively tackle FOG build up and provide a boost in COD turnover in systems such as those treating effluents from dairies and slaughterhouses. Furthermore, through diversifying the extracellular enzyme capability, the product is robust enough to tackle both animal and plant-based materials in effluents, offering a much greater ability for the complete degradation of organic materials.
