Which of the following are dangerous gasses that are Natural gas, gasoline fumes, hydrogen sulfide and carbon dioxide
likely to be present in lift stations and manholes?
A preferred hydraulic method of cleaning sewer lines Hydro Jet Cleaner
is
Ways to reduce bad odors coming from a collection routinely cleaning slow running or low flow lines, adding chlorine or
system hydrogen peroxide to the collection system
Types of pipe that are commonly used in wastewater ductile iron, Poly Vinyl Chloride (PVC)
collection system
Before entering a confined space a worker should Use approved monitoring device and check for the presence of dangerous
gasses, ventilate the space with a blower, wear a safety harness and attach a
life line
A properly designed and operated primary 30-40%
sedimentation tank should remove _____ percent of
incoming BOD
