Trickling filter process is one of the types of aerobic wastewater treatment. It is a fixed-bed bioreactor that is the part of secondary wastewater treatment, which eliminates the coarse particles, suspended organic and inorganic waste, small colloids etc. out of the primary effluent. A trickling filter is also called biological filter, as it makes the …
Activated sludge treatment can define as a conventional method, which can separate the solid wastes, suspended organic matter, soluble matter and parasites. It is a biological system that makes the use of living bacterial flocs to degrade the organic matter of the sewage and industrial waste in aerated bioreactors. Activated sludge treatment involves a series …
Ozone formation takes place differently in the stratosphere region and the troposphere region of the earth’s atmosphere. The heat or sunlight causes chemical changes or dissociates molecules of oxygen into individual atoms, which can further react with the atmospheric oxygen to form stratospheric ozone. In contrast, the heat or sunlight causes chemical reactions in the …
Difference between absorbent and adsorbent is mainly due to the following factors like their mechanism and the phenomena they follow: Mechanism: The mechanism of absorbent and absorbent is to retain the particles or molecules, in which a former absorbs the particles into the matrix, and the latter adsorbs the particles over the solid matrix. Phenomena: …
Prokaryotic ribosomes are dense structures, which solely contain RNA and proteins. The ribosomes in the prokaryotic cell are thoroughly distributed in the cell cytosol. There are two subunits of prokaryotic ribosomes (50-S and 30-S type). 50-S and 30-S are the large and small subunits of bacteria that colloquially constitute the 70-S type of ribosome. Here, …
Inclusions in prokaryotes include certain types of food reserve granules and some monolayered non-unit membrane-enclosed cytoplasmic inclusions. Cell inclusion bodies can define as the pigmented molecules, which resides within the cell. It does not function like membrane-bound organelles but performs a pivotal role to store reserve materials. Inclusion bodies occupy within the cytosol enveloped by …
ATP synthase is a transmembrane enzyme complex, which catalyses the generation of ATP through the condensation of ADP plus Pi. Its primary role is to produce high energy ATP molecule. ATP synthase brings out the formation of ATP at the time of light-reaction photosynthesis. Its working depends upon the proton gradient created in the thylakoid …
A floral formula is one of the ways to summarise all the flower characteristics, which makes the use of discrete letters, numbers and symbols. The letters used in the floral formula indicate the members of the perianth and other floral parts. Specific signs or symbols are also used to denote the properties like parentheses, aestivation, …
The difference between nucleus and nucleolus is mainly due to the following factors: Location: Nucleus is the core central organelle of the eukaryotic cell, while nucleolus resides interior to the nucleus. Size: The size of the nucleolus is very small compared with the size of the nucleus. Under the microscope, the nucleus appears as a …
Aestivation in plants can be defined as the arrangement of the petals and sepals, collectively called as perianth inside a floral bud before blooming. It is an important tool in the study of plant taxonomy, in which flowers of the different family show distinct aestivation. For instance, the sepals and petals of the Hibiscus flower …
