What is the major purpose of biological treatment in wastewater treatment?
The goal of biological wastewater treatment is to create a system in which the results of decomposition are easily collected for proper disposal. Biological treatment is used worldwide because it's effective and more economical than many mechanical or chemical processes.
How does Novozymes dispose of cell waste after recovery?
The production site now sends the majority of its solid waste to a local cement kiln for energy recovery and the organic food waste for animal feed. In 2016, the total solid waste disposed of to landfill and/or incineration was 6,420 tons. The rate of recycling of solid waste was 44% in 2016, compared with 50% in 2015.
What is biological treatment waste?
2.3 Advanced Biological Treatment (ABT) Options All biological waste treatment processes involve the decomposition of biodegradable wastes by living microbes (bacteria and fungi), which use biodegradable waste materials as a food source for growth and proliferation.
What do Novozymes do?
Novozymes produces enzymes by fermenting microorganisms which can be genetically modified to improve the production process. Enzymes are proteins, not living organisms, and contain no genetically modified organisms.
What is the enzyme?
Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain enzyme can cause health problems. Enzymes in our blood can also help healthcare providers check for injuries and diseases.
What is biological treatment What are the advantages of biological treatment?
Compared to other treatment methods, biological methods have certain advantages such as (1) treatment technology is traditional and well understood; (2) enhanced efficiency in terms of organic content removal; (3) cost-effective; and (4) environment friendly and safe.
How does a biological treatment work?
Biological therapy (also called immunotherapy, biological response modifier therapy, or biotherapy) uses the body's immune system to fight cancer. The cells, antibodies, and organs of the immune system work to protect and defend the body against foreign invaders, such as bacteria or viruses.
What is the basis of biological treatment process?
Biological treatment methods use microorganisms, mostly bacteria, in the biochemical decomposition of wastewaters to stable end products. More microorganisms, or sludges, are formed, and a portion of the waste is converted to carbon dioxide, water, and other end products.
What do you mean by biocatalyst?
Biocatalysis is defined as the use of natural substances that include enzymes from biological sources or whole cells to speed up chemical reactions. Enzymes have pivotal role in the catalysis of hundreds of reactions that include production of alcohols from fermentation and cheese by breakdown of milk proteins.
What type of company is Novozymes?
biotechnology companyNovozymes A/S is a global biotechnology company headquartered in Bagsværd outside of Copenhagen, Denmark. The company's focus is the research, development and production of industrial enzymes, microorganisms, and biopharmaceutical ingredients.
How big is Novozymes?
Novozymes holds an estimated 48% share of the global enzyme market. Total sales in 2019 were DKK 14,374 million, a decline of 1% organically and flat in DKK. Overall unsatisfactory sales growth in 2019 mainly due to challenging agricultural markets.
Where does Novo Nordisk use wastewater?
Novozymes and Novo Nordisk use wastewater from the factories in Kalundborg for a large scale production of biogas. The new biogas reactor produces as much electricity as 7 offshore wind turbines, reduces CO2 emissions and lowers energy costs.

What is bioaugmentation in wastewater?
Microorganisms are the heart of any biological wastewater. system. In bioaugmentation, specialized microbial strains. are added to strengthen the existing microbial community. Bioaugmentation is the cost-effective way to simplify your. operations and improve treatment efficiency.
Why is bioaugmentation important?
Bioaugmentation is especially useful when you can't get high-quality sludge that's acclimated to your industry locally. Once your system is up and running, you can boost its efficiency by adding microorganisms that degrade target compounds. This approach is particularly useful if your plant is undersized.
How efficient is a chemical plant?
Efficient: A chemical plant reduced effluent ammonia by 97.5% and a municipal plant improved cold weather ammonia removal by 17%. Cost-effective: A dairy plant saved $40,400 a year in chemical, disposal and labor costs. Simple: A petrochemical plant decreased recovery time from shock loads by more than 30%.

How does biological wastewater treatment work?
Biological wastewater treatment is designed to degrade pollutants dissolved in effluents by the action of microorganisms. The microorganisms utilize these substances to live and reproduce. Pollutants are used as nutrients. A prerequisite for such degradation activity, however, is that the pollutants are soluble in water and nontoxic. Degradation process can take place either in the presence of oxygen (aerobic treatment) or in the absence of oxygen (anaerobic treatment). Both these naturally occurring principles of effluent treatment give rise to fundamental differences in the technical and economic processes involved (Table 2 ).
What is phytoremediation in wastewater treatment?
Phytoremediation method: This is another biological method for wastewater treatment. The combination of two Latin words―plant and remedy―gave rise to the term phytoremediation. The plant, plant origin microbes, or associated microbiota are used to take up the contamination from soil or water.
How does decolorization occur?
The decolorization by bacterial process may occur by aerobic, anaerobic, or a combination of both processes. Under aerobic condition, azo dyes are not willingly metabolized. It creates more toxic aromatic amine compounds. Thus to achieve complete degradation, aerobic degradation is followed by an anaerobic degradation process. [42]. In the case of phthalocyanine chromophores, reversible decolorization and reduction occurs only via an anaerobic method. Horitsu et al. first reported degradation of azo dyes using Bacillus subtilis culture [43].
Why do aerobic microorganisms need oxygen?
Aerobic microorganisms require oxygen to support their metabolic activity. In effluent treatment, oxygen is supplied to the effluent in the form of air by special aeration equipment. Bacteria use dissolved oxygen to convert organic components into carbon dioxide and biomass.
How is phytoremediation achieved?
The remediation is achieved either by retaining, elimination, or degradation in a natural way as it happens in an ecosystem. Phytoremediation is a cheaper, eco-friendly, and feasibly sustainable method for removal of dye pollutants. Moreover, the process requires little nutrient cost and also has aesthetic demand.
What is the resultant of cleavage?
The resultant of cleavage is lethal aromatic amine that can be later decomposed by the aerobic process [59,60]. Laccase is a small molecular weight, multicopper-containing enzyme that degrades dye substrate with less specificity.
What are the two types of enzymes that catalyze dye degradation?
Two types of enzymes are known: lignin and manganese peroxidases (MnP). Each of them shows almost the same reaction mechanism.
Why do we use enzymes?
When one substance needs to be transformed into another, nature uses enzymes to speed up and control the process. With Novozymes’ expertise, enzymes can be used on an industrial scale to optimize output, deliver better products and accelerate processes, while saving water, energy and raw materials.
