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 ...
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).
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.
Together, the collection, transport, treatment and end use of fecal sludge constitute the "value chain" or "service chain" of fecal sludge management. Fecal sludge is defined very broadly as what accumulates in onsite sanitation systems (e.g. pit latrines , septic tanks and container-based solutions) and specifically is not transported through ...
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. More ...
These methods are based on continuous monitoring of process variation. The control chart, also known as the Shewhart chart or process-behavior chart, is a statistical tool intended to assess the nature of variation in a process and to facilitate forecasting and management. A control chart is a more specific kind of run chart.
The new 12-team College Football Playoff is about to begin, and the journey to crown the national champion starts now.
Chemicals in use in industry and research have a range of properties which cause them to be hazardous to life. These include explosiveness, flammability, toxicity, carcinogenicity and teratogenicity. [4] Corrosive substances such as strong alkalis or acids can cause chemical burning. Any one chemical or mixture may exhibit several of these ...
