American versions include Standard Methods for the Examination of Water and Wastewater. [4] Any oxidizable material present in an aerobic natural waterway or in an industrial wastewater will be oxidized both by biochemical (bacterial) or chemical processes. The result is that the oxygen content of the water will be decreased.
An alkaline hydrolysis disposal system at the Biosecurity Research Institute inside of Pat Roberts Hall at Kansas State University. Alkaline hydrolysis (also called biocremation, resomation, [1] [2] flameless cremation, [3] aquamation [4] or water cremation [5]) is a process for the disposal of human and pet remains using lye and heat; it is alternative to burial, cremation, or sky burial.
Electro-biochemical reactor (EBR) is a type of a bioreactor used in water treatment. EBR is a high-efficiency denitrification , metals, and inorganics removal technology that provides electrons directly to the EBR bioreactor as a substitute for using excess electron donors and nutrients.
Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...
A bioassay is a biochemical test to estimate the potency of a sample compound. Usually this potency can only be measured relative to a standard compound. [3] [1] A typical bioassay involves a stimulus (ex. drugs) applied to a subject (ex. animals, tissues, plants). The corresponding response (ex. death) of the subject is thereby triggered and ...
BOD test bottles at the laboratory of a wastewater treatment plant. Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period.
The high water level (hydraulic head) in the inlet reservoir zone pushes the water through the diffuser and filter, then decreases as water flows evenly through the sand. The flow rate slows because there is less pressure to force the water through the filter. The inlet water contains dissolved oxygen, nutrients, and contaminants.
Bioreactor. Biochemical engineering, also known as bioprocess engineering, is a field of study with roots stemming from chemical engineering and biological engineering.It mainly deals with the design, construction, and advancement of unit processes that involve biological organisms (such as fermentation) or organic molecules (often enzymes) and has various applications in areas of interest ...
