Wastewater engineering is not usually its own degree course, but a specialization from degrees such as environmental and sanitary engineering, sanitary engineering, civil engineering, environmental engineering, bio-chemical engineering, or chemical engineering. Formal education for wastewater engineers begins in high school with students taking ...
Commonly used indicators for bacteriological water analysis include the bacterium Escherichia coli (abbreviated as E. coli) and non-specific fecal coliforms. With regards to samples of soil , sewage sludge , biosolids or fecal matter from dry toilets , helminth eggs are a commonly used indicator.
The definition of ecosan has varied in the past. In 2012, a widely accepted definition of ecosan was formulated by Swedish experts: "Ecological sanitation systems are systems which allow for the safe recycling of nutrients to crop production in such a way that the use of non-renewable resources is minimized.
Quantitative chemical analysis is a key part of environmental chemistry, since it provides the data that frame most environmental studies. [11] Common analytical techniques used for quantitative determinations in environmental chemistry include classical wet chemistry, such as gravimetric, titrimetric and electrochemical methods.

Chemical engineers use chemistry and engineering to turn raw materials into usable products, such as medicine, petrochemicals, and plastics on a large-scale, industrial setting. They are also involved in waste management and research.
Hygiene is a practice [3] related to lifestyle, cleanliness, health, and medicine.In medicine and everyday life, hygiene practices are preventive measures that reduce the incidence and spread of germs leading to disease.
The following outline is provided as an overview of and topical guide to chemical engineering: . Chemical engineering – deals with the application of physical science (e.g., chemistry and physics), and life sciences (e.g., biology, [[microbi logy]] and biochemistry) with mathematics and economics, to the process of converting raw materials or chemicals into more useful or valuable forms.
Dimensional analysis may be used as a sanity check of physical equations: the two sides of any equation must be commensurable or have the same dimensions. A person who has calculated the power output of a car to be 700 kJ may have omitted a factor, since the unit joules is a measure of energy, not power (energy per unit time).
