(Latest Update ) Questions
with Correct Answers {Grade A} 100%
Verified
Service - correct answer is the action of performing activities such as, but not limited
to, inspection, assessment, and maintenance of system components.
Single-pass - correct answer refers to the flow of wastewater through a treatment
component. It is only treated by a component one time in the treatment train.
Solids analysis - correct answer measures the amount of solids present in
wastewater. Typical analyses include total suspended solids (TSS), total dissolved
solids (TDS), or total solids.
Time-dosed - correct answer systems use an adjustable timer on a pump to control
the flow of wastewater to the next treatment component. The system operator can set
the timer to turn on the pump for a set amount of time to deliver only a pre-
determined volume of wastewater to the next component.
,Total Kjeldahl Nitrogen (TKN) - correct answer is the sum of organic nitrogen and
ammonia in a water body.
Total Phosphorus (TP) - correct answer is a measure of all the forms of phosphorus,
dissolved or particulate, present in water.
Total Dissolved Solids (TDS) - correct answer are the solids in water that are able to
pass through a filter.
Total Solids - correct answer refers to matter suspended or dissolved in water. It is
the term used for material left in a container after evaporation and drying of a water
sample. Total Solids includes both total suspended solids and total dissolved solids.
Total Suspended Solids (TSS) - correct answer are solids in water that can be trapped
by a filter.
, Treatment Train - correct answer is the unique combination of technologies that make
up an individual onsite wastewater treatment system. An example of a treatment train
would be a septic tank and a soil adsorption area. All components in a treatment train
require operation and maintenance.
Troubleshooting - correct answer is the act of identifying and correcting sources of
system malfunction.
Turbidity - correct answer is the physical clarity of the water and is an indicator of the
presence of total suspended solids in wastewater.
Unacceptable - correct answer is a condition in which a component is not operable.
This condition indicates the need for implementing maintenance, upgrades, repairs, or
further investigation.
Upgrade - correct answer is the action of creating a better system by adding or
modifying a component to improve the level of treatment provided by a system.
