Microbiology
a bacterium, virus, or other microorganism that can cause disease.
Pathogen
government agency that regulates effluent quality standards
EPA (Environmental Protection Agency)
a measurement of how acidic or basic a liquid is
pH
the visible or invisible radiation emitted by certain substances as a result of incident radiation of a shorter wavelength such as X-rays or ultraviolet light.
fluorescence
the acronym for the lab group that is presenting to you today
WIRL
type of pathogen that is resistant to disinfection
Helminth (Parasitic worm), Protozoa
removal through physical separation
Filtration
Two parameters that are used to measure water quality
pH, turbidity, BOD/COD, DO, conductivity, nutrients, pathogens (microbiology), total solids
This light is invisible to the human eye but is very important for life. It makes black-light posters glow, and is responsible for summer tans and sunburns.
Ultra-violet (UV) light
Lauren's favorite color
periwinkle (black can also be accepted)
pathogen that cannot be removed by filtration
virus
three types of disinfection
ozone, UV, chlorine (NEED ALL THREE)
water category that excludes urine and feces. This water can be used for toilet flushing and agriculture purposes.
greywater
UV / Vis ________ uses visible light and ultraviolet to analyze the chemical structure of substance.
spectrophotometer/spectrophotometry
An outbreak of _________ , a type of protozoa resistant to disinfection, led to the death of 100 people in Milwaukee.
Cryptosporidium
type of pathogen smaller than helminths but larger than bacteria
protozoa
a treatment step that differentiates wastewater treatment from water treatment
Sand Filtration, Disinfection, Aeration, Secondary Clarification (NEED ONE)
a parameter which correlates to the ions present in a water sample
Conductivity
color is composed of a broad range of _______ in the ultraviolet (UV), visible and infrared (IR) portions of the spectrum
wavelengths
two constituents found in influent entering a water/wastewater treatment plant
Chemicals of emerging concern (from PPCPs) Debris, Heavy metals, pathogens, nutrients
order of pathogens, by name, in order of increasing size
Viruses, Bacteria, Protozoa, Helminths (Parasitic Worms)
Disinfection damages _______ on a microorganism, leaving it unable to reproduce.
Cell wall
Nutrient found in wastewater which comprises 80% of its total amount from urine
Nitrogen
special substances emit visible light in response to radiation.
an infection caused by a parasitic worm found in tropical, freshwater. Lives a symbiotic relationship with snails and, penetrates through human skin. Initial symptoms include dizziness, fever and a rash. Chronic infection can lead to seizure and paralysis.
Schistosomiasis
