Applications

Municipal and industrial wastewater plants

Grease traps and interceptors

Suited to effluents rich in organic materials

The technology

Evogen Biobricks have been specially formulated to be used as a controlled release technology in wastewater treatment systems to boost performance, 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 brick 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 chosen 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 Biobricks give the operator a versatile technology to tackle a multitude of scenarios at both large and small treatment works.

Typically, the resident microbes within a wastewater system lack the capability to fully degrade FOG leading to deposits rich in fatty acids such as the saturated fatty acids palmitic and steric acid and unsaturated fats such as oleic and linoleic acid.  This can lead to issues associated with clogging, bulking and floc formation.

Developed using both classical microbiology and cutting-edge genomic investigations, the Evogen Biobrick combines Bacillus strains which secrete a diverse range of enzymes and biosurfactants to break different FOG types down to more digestible components.

This allows the Bacillus within the product to colonise a system and utilise the FOG as their food source, potentially outcompeting filamentous organisms such as Norcaria sp.

Enzymes, chemical and poorly designed products may only facilitate the dislodging of FOG moving it downstream and causing the formation of hard FOG scale. At Genesis we have ensured that our Bacillus consortia not only have the tools to make FOG more bioavailable, but also fully degrade FOG and its intermediates to CO2 and water. In addition, the Bacillus in the Evogen Biobrick possess diverse extracellular enzyme profiles, facilitating broad substrate utilisation and enabling the degradation of both animal and plant materials resulting in improved effluent and sludge parameters.

Directions for use

Evogen Biobricks are supplied in 0.5kg, 1kg and 5kg brick sizes.

These can be placed into wet wells (lift stations, manholes), grease traps or interceptors and/or directly into effluent streams.

For dosing instructions and specialised effluent types, please contact technical support with details of your flows and loads.

Considerations

Evogen Biobricks should be used in systems dealing with organic rich wastewaters that contain materials such as proteins, carbohydrates and fats, oils and grease such as municipal plants, bakeries, dairies and slaughterhouses.

Limitations

The product will perform poorly in highly alkaline (>pH 10) and highly acidic (<pH 3) effluents and will also have decreased activity at low (<10 ̊C) and high (>45 ̊C) temperatures. Effluent types rich in phenolic and hydrocarbon species such as those from wineries, olive mills or heavy industry are not suitable for this product.

Safety

Via both cell cytotoxicity assays and genomic screens for toxin production, we can confirm that all Bacillus species and strains within the product are safe to use, harbour no toxicity towards humans or animals and do not have a negative impact upon the environment.

From analysing the DNA of our strains we can confirm a lack of mobile genetic elements, which strongly indicates a low potential for transmission of antimicrobial resistance (AMR) genes.
