absorption taking in substance into body of another
acid A substance that increases the hydrogen ion concentration of a solution.
lowers PH
corrosive
activated sludge produced in raw or settled wastewater by the growth of bacteria, in the presence
of dissolved oxygen.
activated sludge process A biological wastewater treatment process which speeds up the decomposition
of wastes in the wastewater being treated. Activated Sludge is added to
wastewater and the mixture (mixed liquor) is aerated and agitated. After some
time in the aeration tank, the activated sludge is allowed to settle out by
sedimentation and is disposed of (wasted) or reused (returned to the aeration
tank) as needed, the remaining wastewater then undergoes more treatment.
, adsorption The process of binding or sticking to a surface.
advanced waste treatment Any process of water renovation that upgrades treated wastewater to meet
specific reuse requirements.
aeration the process by which air is circulated through, mixed with or dissolved in a liquid
or substance.
aerobes Bacteria that require oxygen to grow
aerobic bacteria bacteria that use oxygen for cellular respiration
air lift type of pump, air injected at the bottom to lift water to the top, like percolator
coffee pot
algae microscopic plants. live in or on water or on structures near water, make o2 during
day, use o2 at night, affect PH and DO
aliquot A portion of a well-mixed sample removed for testing
alkalinity ability of water to buffer acids
anaerobic Process that does not require oxygen
anaerobic bacteria bacteria that do not require oxygen to survive
anaerobic digestion is the decomposition of waste under anaerobic conditions to produce biogas and
a compost-like residue
anoxic oxygen deficient less than .5 ppm
bacteria (microbiology) single-celled or noncellular spherical or spiral or rod-shaped
organisms lacking chlorophyll that reproduce by fission
baffle board used to direct flow, uniform velocities, absorb energy, divert, guide, agitate
liquids
base a compound that produces hydroxide ions in solution. raises PH
biomass the total mass of organisms in a given area or volume.
