The production of biogas from wastewater is an efficient and sustainable process that is becoming increasingly important in industrial wastewater treatment. Particularly in the food industry, dairies, the sugar industry and in the treatment of flotate sludge, biogas production offers an excellent opportunity to utilize organic waste materials and simultaneously generate energy.
A biogas plant is a technical facility for the anaerobic treatment of organic waste and wastewater in which biogas is produced in the absence of oxygen. This biogas, which consists mainly of methane (CH₄) and carbon dioxide (CO₂), is then used to generate energy. The anaerobic process enables the utilization of organic substances from wastewater,
A bioinhibitor is a chemical substance that inhibits or controls the growth and activity of microorganisms in water circuits and water treatment systems. The primary use of bioinhibitors is to prevent or minimize biofouling in membrane filtration systems, cooling water systems and other industrial systems. Biofouling is caused by the growth of
Biologically activated filtration (BAF) is a water and wastewater treatment process that combines biological and physical processes to remove organic matter, nutrients (such as nitrogen and phosphorus) and other impurities from water. In contrast to conventional filtration systems, which work purely physically, the biologically activated
Biodegradability describes the ability of organic compounds to be broken down by the metabolic processes of microorganisms such as bacteria, fungi or algae. In industrial water and wastewater treatment, this property is of crucial importance for assessing the environmental compatibility of substances and developing suitable treatment processes. Technical principles The
Biological deposits, also known as biofilms or biofouling, are accumulations of microorganisms such as bacteria, algae, fungi and other biological materials on surfaces in contact with water. These deposits occur in many industrial water circuits, such as cooling water systems, membrane systems (reverse osmosis) and pipelines, and represent a challenge for
Biological wastewater treatment is a key process for the purification of industrial and municipal wastewater. It uses the natural metabolic processes of microorganisms to remove organic compounds, nutrients and pollutants from wastewater. The biological processes that are used are based on the ability of bacteria, fungi
Biomass recirculation is a crucial process in biological wastewater treatment in which the sludge containing a high concentration of active microorganisms is returned to the biological reactor system. This step enables effective and stable biological purification by maintaining a sufficiently high concentration of microorganisms in the system.
A biocide is a chemical substance or microorganism that is specifically used to combat harmful organisms such as bacteria, fungi, algae or viruses or to inhibit their growth. Biocides play a central role in industrial water treatment and wastewater treatment, particularly in cooling water systems, membrane systems (e.g. reverse osmosis), heat exchangers and
Biocinosis refers to the totality of all living organisms, in particular microorganisms, that live together and interact in a specific ecosystem or technological system. In biological wastewater treatment or in biofilters, the biocenosis is decisive for the performance of the system, as the microorganisms break down pollutants through their metabolic processes. The composition
