in combination with other contributing industries, on that treatment
works or upon the quality of effluent from that treatment works.
MILLIGRAMS PER LITER
A unit of the concentration of water or wastewater constituent.
It is 0.001 gram of the constituent in 1,000 milliliters of water.
It has replaced the unit formerly used commonly ("parts per million")

concentration expressed by one of the procedures outlined in Standard
Methods.
POPULATION EQUIVALENT

waste on a treatment works or stream. One population equivalent is
100 gallons of sewage per day, containing 0.17 pound of BOD and 0.20
pound of suspended solids.
PPM
Parts per million by weight.
PRETREATMENT
The treatment of wastewater from sources before introduction
into the wastewater treatment works.
PROPERLY SHREDDED GARBAGE
The wastes from the preparation, cooking and dispensing of
