Aster Bio’s in-house specializations include system audits, biomass analysis using our Environmental Genomics testing, treatability testing, toxicity evaluation, and custom designed bioaugmenation products and application techniques.
Often wastewater consultants are also selling chemicals, equipment or laboratory services. Aster Bio is unique – we focus on the science of biological waste treatment. While we do manufacture custom microbial blends for use in bioaugmentation, Aster Bio’s main goal is to work with the customer to improve overall treatment results. We have introduced the use of 16S DNA screening to determine which organisms are doing the work and how making changes impacts the overall microbial ecology. Instead of relying on the same bioaugmentation technology of the 1980s, Aster Bio is constantly screening new strains and building a culture bank of microbes with unique properties and the ability to enhance biological treatment.
Bioaugmentation is the science of adding specially cultured microbes to a working environment. The goal is to introduce microbes with unique properties enhancing the conversion of wastes into harmless microbial byproducts. Success is determined by the ability to the organisms to enter the system and multiply making up a significant portion of the overall microbial population. Learn more.
Bioaugmentation is used in systems facing fluctuating conditions. Such fluctuations include flow variation, influent chemical makeup or concentration, environmental conditions (temperature, pH, D.O., etc), and when the system’s indigenous microbial population is not desirable (filamentous bulking, GAO versus PAO in phosphate removal). In cases where bioaugmentation is merited, Aster Bio uses the latest in scientific research to create the correct microbial blend for the application. Equally important are the techniques to introduce the organisms to the system. In both formulation and introduction, Aster Bio has the most advanced knowledge on the market.
Waste treatment is expensive. Aster Bio understands that maximizing the impact of current equipment and resources is key to controlling waste treatment costs. Aster Bio has helped to control costs by:
- Reducing chemical use, including polymers and antifoams
- Lowering the use of activated carbon when treating toxic and quasi-toxic compounds
- Reducing sludge volume in lagoons and digesters and reducing the volume going to dewatering and off-site disposal
- Extending the life of existing treatment units and avoiding unplanned capital expenditures
- Maintaining full compliance under adverse conditions
By optimizing biological treatment unit performance, Aster Bio has often extended the working capacity and life of wastewater treatment plants. Often Aster Bio can work to improve conditions for microbe growth and add cultures when needed to keep the system within ideal steady-state conditions.
Aster Bio’s bioaugmentation cultures were designed for convenience and long shelf life. As soon as operators see a problem with biomass activity, as indicated by routine daily testing, they can respond with a set bioaugmentation protocol designed to quickly restore the biomass to full treatment efficiency. The ability to quickly respond without importing sludge or having to maintaining complex on-site equipment makes Aster Bio’s cultures ideal for the facility experiencing only periodic biomass problems.
In facilities operating at full capacity with frequent changes in influent quality, an onsite Biomass Matrix Unit™ can be installed to activate and grow cultures. As with our bioagmentation formulations, Aster Bio’s patent-pending Biomass Matrix Unit™ activates a custom blend of microbes grown on influent wastes to full activity before adding to the system. Unlike older “bug farms”, the Biomass Matrix Unit™ grows the cultures on the target waste stream and does not have any cleaning requirements to remove messy bran carriers. Adding cultures to the unit is done by periodic replacement of the culture matrix with new materials taking less than 10 minutes.
