Waste water treatment
Biodegradation products assist wastewater treatment plants that just cannot degrade specific compounds. This issue can be caused by multiple factors: the variability of the compound(s) in the influent may not allow the biomass to acclimate to the material, or, the system may not be designed to achieve removal—for example; not enough residence time or high enough sludge age to achieve nitrification. In addition, the wastewater discharge permit limitations can change to require removal of specific compounds due to water quality limitations or regulatory mandates. If regulations change, influent wastewater changes, or plant operations change, the biological process of the system must be able to meet the new goals or deal with the new environment.
An effective way to improve the overall system is to improve the ability of the wastewater system’s biomass to degrade the target compound. By seeking out biodegradation products with microbes that are extremely good at degrading compounds and supplementing the biomass with them, the biomass can be changed to better remove a specific compound. This could be by either improving the speed or ultimate removal of the compound, or by making the biomass less susceptible to upsets that have negative effects on the removal rate.

Hydrocarbons are often degraded slowly in the wastewater treatment process. At high
concentrations, hydrocarbons can cause an increase in oil and grease in the final effluent and lead to filamentous outbreaks. Hydrocarbons can also become entrained in the floc. This can cause settling problems and biomass toxicity and may lead to complications with effluent toxicity.
Whether hydrocarbons are degraded completely, partially, or not at all depends on the type and functionality of the microorganisms in the microbial community.
BioRemove 2300 contains a variety of organisms that rapidly degrade hydrocarbons like alkanes and aromaticcompounds. It is the most effective biological product available for improving hydrocarbon degradation in wastewater treatment.
Phenol can cause serious problems in the wastewater treatment process. In high enough concentrations, phenols can lead to toxicity and floc disruption. As a result, treatment becomes less efficient, settling worsens, and the plant could be at risk of permit violations.
Phenols are degradable, but if the right microorganisms are not present or functional, plant stability and effluent quality could be
BioRemove 2500 is an effective biological solution for degrading phenols and
improving plant stability. The microorganisms in BioRemove 2500 were selected
for their degradation abilities and their tolerance of high concentrations of phenols.
Industrial wastewater presents a unique set of treatment challenges. Waste streams are constantly changing with production with harsh chemicals often making their way into the wastewater which can inhibit biological activity and be difficult to break down. A key variable in the process that determines success or failure of a treatment process is the types of microorganisms in the microbial community and the ability of the microbial community to adapt to changes in the waste stream.
BioRemove 5100 is Novozymes’ most versatile product for industrial wastewater and is effective for highly complex waste streams. It has a diverse set of microorganisms that target a wide range of organics found in a variety of industries. BioRemove 5100 has the broadest range of biological activity and helps keep plants in compliance and in control.
Ammonia removal is one of the most important and difficultprocesses to maintain in wastewater treatment plants. It can beimpacted by various environmental factors, shock loading, toxicity, and solids loss. Success or failure of the process depends on the
ability of microbial community to degrade ammonia, tolerate harshconditions, and respond quickly after nitrification disruptions.
BioRemove 5805 is a unique nitrification technology for a variety ofwastewater types. The microorganisms in BioRemove 5805 thrive in a widerange of wastewater types and respond quickly during upsetconditions to restore nitrification. It is the most effective biological solutionfor nitrification.
