0 a stream that flows into another stream
1 water or other liquid that flows into a waste treatment centre:
2 flowing into something:
The influent raw sewage has a high organic concentration.
The influent in sewage water passes through a bar screen to remove all large objects like cans, rags, sticks, plastic packets etc. carried in the sewage stream.
In an aerobic treatment system, influent first enters an aeration tank where the powdered carbon is added, making up a portion of mixed liquor suspended solids.
The reactor used the effluent from a methanogenic pilot reactor, which contained ammonium, sulphide and other compounds, and nitrate from a nitrifying plant as the influent.
Obviously, any measure of pollution control must include both levels of influent and effluent.
The model shows that the inefficiency effects are not a linear function of effluent-influent ratio of various pollutants.
Also, there is a positive association between pollution control and economies of scale (the higher the scale economies, the lower the effluent-influent quality ratio).
The measure chosen here is the ratio of effluent to influent; a lower value of the ratio reflects a higher level of control.
When we think of the great power and influents which this country exercises we cannot look back with much pleasure on our foreign policy in the last five years.
