Introduction to industrial biofilms and their Secondary containment
The secondary spill containment Biofilms or biofilms appear to be present in all sectors of the distribution system for drinking and industrial water. The thin layer of biosynthesis is the main factor in the creation of moss closing in industrial water systems. Moss has a lot of effects, damaging materials, wasting products, and affecting their quality. The problem of moss closure is practical, as the development of a thin layer of biofilm is defined beyond the threshold of interference. Therefore, it is imperative that plant officials keep the thin layer of biofilms under the threshold intact and achieve the threshold values for technical systems. The bio-industrial thin films are very diverse, and the knowledge obtained for a particular type of thin-layer biological layer may not be applicable to other types.
In recognizing this, we can say that the past concept, which exists for the most effective and universal biologist, is a meaningless concept because physical, chemical and biological parameters of the water source vary from one point to another, and therefore the biological practice based on parameters Is different. The containment methods should be based on a technical system and not be generalized to other systems. Because of these complexities in technical systems in the industry, it is necessary to understand the processes of thin-layer biological processes, identify, control and manage them for the operation of factories. A successful anti-ghosting method involves preventing (regular disinfection, preventing the development of a thin layer of biosynthesis beyond the threshold of interference), eliminating microorganisms, and cleaning the surfaces. Killing microorganisms does not necessarily mean the concept of cleaning, as many industrial systems use biotransformation only for killing, while the cleaner is not achieved. Cleaning is necessary to fade dead cell mass on the surface because this dead mass cell provides a suitable level and a food source for the next connection of living organisms.
The secondary spill containment first step in the thin-layer biological control program is the identification and evaluation of various components of the biological layer such as slimy layer thickness, available bacterial and algal species, extracellular polymer content (EPS) and mineral components. Prior to the adoption of the amount and type of biocides in the industrial system, laboratory tests using Side-Stream monitoring devices and under dynamic conditions in order to investigate their effects. Support methods on the line  should be used and regulators quantity of biocide  in order to keep the thin layer of biological containment should be used. There is a thin layer of bio-containment procedures in technical systems, however, the inhibitory methods depending on cost, time limits cleanliness level (interference threshold) for a technical system, the need is. At present, the use of strong oxidants such as biomass, such as chlorine dioxide in cooling systems and ozone, has been shown to be highly inefficient against the thin-layer water distribution systems.
There are a number of nonoxidant bioassays, but the effects of long-term use of them on the environment are still unclear. New methods for containment of thin biological layer such as ultrasonic, electric field, hydrolysis of extracellular polymeric materials, and methods for changing the adhesion and cohesion of the thin-layer biological layer are still in their early stages at the laboratory levels and have not been able to be used in large industrial systems.
Water from natural sources is the main source of cooling for the release of thermal output from heat exchangers and industrial processes. The use of pure water does not eliminate the moss problem, because pure water still contains a small amount of organic carbon, and so there will still be moss problems. Apart from these desalination plants, secondary spill containment they also have a mosquito closure due to the accumulation of a thin layer of biofilm on the pipe and the surface of the membrane. There are also problems with biodegradation in natural water rotating systems open and closed in power plants and in sewage membranes, and hence the problems with these systems are discussed in this chapter.
Events that lead to surface degradation include:
- Natural waters contain large quantities of molecules released by the breakdown of dead microorganisms. These materials absorb floating surfaces containing the initial layer.
- At first, the bacteria are connected to these surfaces and held in the substrate by weak electrostatic forces, hydrogen bonds, and van der Villa forces.
- When the bacteria grow, extracellular polymeric material (EPS) is produced, so the bacteria are placed in an extremely juicy matrix and accumulate. Polymer materials are mainly composed of polysaccharides, proteins, new calcium, and lipid acids. In most cases, this polymer matrix is presented as a barrier to penetration, but this is not the case with small molecules such as bismuth, because it is the main component of the matrix of water. Therefore, the penetration coefficient for such a molecule is very close to the penetration coefficient in natural water, unless these molecules (biocides) interact with matrix components. This effect is known as the infiltration-reaction limitation. Production (EPS) creates substrate adhesion and matrix coherence, thus increasing the elasticity of the biodegradable layer.
- Since then, beggars and micro-algae have accumulated in the substrate and in the thin-layer bio-layer, the thickness of the biofilm layer is increased and it traps food from a mass of water.
Thin-layer biodegradation in industrial systems is an important component in the success of water purification programs. Theoretical approaches consider the early phase of inhibiting the thin-layer biological layer to prevent the initial connection of microorganisms. However, in practice, this hypothesis is not effective because sooner or later the levels of technical systems will be filled up with microcontrollers. The thin-layer biological layer is a source of microbial cells producing and releasing, which affects the number of microbial cells in the water phase. Kodori and colleagues Interesting observations of this effect have been reported: intermittent chlorination increases the 10-fold increase in the release of microbial cells into the water phase without biotic presence.
Therefore, it is very important to control the thin layer of biological material. In conventional surveillance measures, the presence of plankton bacteria is evaluated, while most bacteria are adapted to the aquatic environment and are in the state of solid state or industrial levels, and are neglected. A specific biologist may disable more than one microorganism. drum spill containment With the level of understanding that is currently available to us for the mechanism of biosynthesis and microbial resistance, explaining why some biocides may be effective, factors that are more effective in antimicrobial activity include contact time, concentration, temperature, pH, the presence of organic matter and the type of microorganisms. That’s why it’s almost hard to evaluate the different biogas.
