Biological alternatives for municipal and industrial wastewater treatment
The physical and chemical characteristics of municipal and industrial wastewater treatment vary significantly based on the industry, the processes used and the chemicals used. Novozymes offers effective biological alternatives to traditional municipal and industrial wastewater treatment products, designed specifically for varying industries. Novozymes' microbial-based solutions simplify municipal and industrial wastewater treatment operations, improve plant efficiency and lower operating costs.
Industrial wastewater treatment products for the refinery industry
The processing of crude oil into refined fuel products and the production of industrial chemicals from the by-products of refining, generates a significant amount of wastewater. The constituents and volumes of refinery and petrochemical wastewater vary significantly by refinery process technology. Refinery wastewater is often most concerned with the removal of petroleum hydrocarbons, as well as a range of volatile and semi-volatile organics: alkanes, alkenes, aromatics, phenolics, and the like. Due to the sulfur content of some crudes, the generation of sulfides is also of concern. Novozymes offers advanced industrial wastewater treatment technologies, specially designed for wastewater systems of the refining and petrochemical industry.
Industrial wastewater treatment products for the pulp and paper industry
Paper can be produced in a variety of ways, via both physical and chemical methods, although chemical pulping is the most prevalent method. Chemical pulping creates wastewater that can be extremely difficult to treat and may cause issues with settling, turbidity, nuisance microorganisms and organic breakthrough. When working with pulp and paper wastewater, one should be looking for issues related to season feedstock changes, liquor spills, caustic chemical spills, high temperature loads, as well as the addition of inhibitions from surfactants and biocides. Novozymes produces advanced industrial wastewater treatment technologies, specially designed for the challenges of the pulp and paper industry.
Industrial wastewater treatment products for the food and beverage industry
The production of food products can generate a wastewater stream that is rich in organics, fats, oils and grease (FOG), and nutrients. For example, milk is rich in specific organics such as carbohydrates, proteins and lipids. These organics contribute to high biological oxygen demand (BOD) and FOG loads, and proteins contribute to higher nitrogen levels. Novozymes offers advanced biological wastewater technologies specially designed for the food and beverage industry, including biodegradation of fats, oils, and grease, and improvement of biogas production in anaerobic pretreatment units.
Municipal wastewater treatment products
The principal characteristics of municipal wastewater can be classified as physical, chemical and biological, and depend upon land use, population density, storm water handling, industrial users and domestic water supply. Novozymes offers advanced biological wastewater technologies designed for municipal wastewater treatment plants in order for them to effectively maximize plant efficiency while lowering operating costs and making the plant easier to operate.
