COSC 325 MEP FINAL EXAM QUESTIONS
WITH SOLUTIONS
What is acidity - - Ability of a water solution to neutralize an alkali or base
- What is activated carbon - - Material that has a very porous structure and
is adsorbent for organic matter
- What is aeration - - Process by which air becomes dissolved in water
- What is aerobic - - An action or process conducted in absence of oxygen
- What is Air gap - - The unobstructed vertical distance through the free
atmosphere between the lowest opening from any pipe or faucet supplying
water to a tank, plumbing fixture...
- What is alkalinity - - The quantitative capacity of water to neutralize an
acid
- What is alum - - common name for aluminum sulfate
- What is anaerobic - - Action or process conducted in the absence of
oxygen
- Anion - - An ion with a negative electrical charge
- Aquifer - - Natural water bearing geological formation
- Area drain - - receptacle designed to collect surface or storm water from
an open area
- Artesian - - Water held under pressure in porous geological formations
confined by ipermeable geological formations. Artesian well is free flowing.
- Biochemical Oxygen Demand (BOD) - - Amount of oxygen required in the
oxidation of organic matter by biological action under specific standard test
conditions. Widely used to measure the amount of organic pollution in
wastewater and streams.
- Biodegradation - - Decompostition of a substance into smaller substance
by bacteria
- Brine - - Strong solution of salt; range of 40k-300k mg/L
, - BTU - - British thermal unit;Quantity of heat; 1 BTU will raise1 pound of
water 1 F (1 calorie = 4 BTU)
- BTUH - - British thermal unit per hour
- Cleanout - - Accessible opening in the drainage system used for removal
of obstructions
- Effluent - - Treated wastewater
- Entropy - - capacity of a ststem to hold energy that is not available for
changing the temperature of the system
- Flocculation - - Process of bringing together destabilized or coagulated
particles to form larger masses or flocs, which can be settled and/or filtered
out of the water being treated
- Flood rim - - the edge of a receptacle from which water will over flow
- Flow rate - - Quantity of water or regenerant that passes a given point in a
specified unit of time, GPM
- Flush valve - - Self closing valve for flushing urinals or toilets in public
buildings
- Free groundwater - - Unconfined groundwater whose upper surface is a
free water table
- Gray watter - - Wastewater other than sewage, such as sink drainage or
washing machine discharge
- Groudwater - - Water below the surface of the ground
- Half life - - Time required for half of the substance present at the begining
to dissipate or disentergrate
- Hardness - - Water quality that indicates level of alkaline salts
- Head - - The pressure at any given point in a water system; PSI
- Hydrologic cycle - - Cyclical transfer of water vapor from the earths
surface through evaporation and transportation through the atmosphere
- Interface - - The surface that forms a common boundary between two
spaces or two parts of matter; such as the surface boundary formed between
oil and water
