What Is The Composition Of Activated Sludge?


Activated sludge (AS) is composed of aerobic and anaerobic microorganisms such as bacteria, archaea, fungi, and protists. It is capable of degrading organic compounds, including petroleum products, toluene, and benzopyrene (Seviour and Nielsen, 2010).



What is the composition of wastewater?

The composition of wastewater is 99.9% water and the remaining 0.1% is what is removed. This 0.1% contains organic matter, microorganisms and inorganic compounds. Wastewater effluents are released to a variety of environments, such as lakes, ponds, streams, rivers, estuaries and oceans.

What is your first research question?

A research question is an answerable inquiry into a specific concern or issue. It is the initial step in a research project. The 'initial step' means after you have an idea of what you want to study, the research question is the first active step in the research project.


Why do we use diagrams in math?

Math diagrams make it easier for academics and professionals to convey some form of mathematical relationship. These illustrations can be related to algorithms, velocity, mass, simple comparisons, and even timelines. Students move from a verbal presentation to a visual form, one which is later easier to explain.


What are the reproductive parts in plants?

Structure. As a plant's reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 19). The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament.


What are the 8 steps in the research process?

  1. Identifying the problem.
  2. Reviewing literature.
  3. Setting research questions, objectives, and hypotheses.
  4. Choosing the study design.
  5. Deciding on the sample design.
  6. Collecting data.
  7. Processing and analyzing data.
  8. Writing the report.


What comes first research or research title?

Before we proceed to your Research title, a researcher must be able to identify the problem first. Research problem refers to the research title. The title is a very important part of all thesis documents, as it introduces readers to the nature.

What are the different kinds of transformers?

Types of Transformers

  • Power Transformers. A power transformer transfers electricity between a generator and the distribution primary circuits.
  • Autotransformers. Now, let's make things even more complicated.
  • Generator Step-Up Transformers. Moving right along to GSUs or generator step-up transformers.
  • Auxiliary Transformers.


Is MathWorks a public company?

MathWorks is an American privately held corporation that specializes in mathematical computing software. Its major products include MATLAB and Simulink, which support data analysis and simulation.


What is developing a research plan?

In research, creating a research plan with the key steps you need to go through will help you run a successful research study. A research plan helps align stakeholders, ensuring that everyone is familiar with the project's timeline, goals, and scope.
