Task 1: Through the measurement of electrical conductivity of waste-water one can find out the:

a) Oxygen content.
b) Concentration of total ions.
c) Acidity.
d) Heavy metal content.
e) Concentration of organic acids.

Task 2: In the inflow to a municipal wastewater treatment plant the COD = 1000 mg/l and the BOD5 = 500 mg/l. From such figures it can be recognized that one is concerned with:

a) Industrial and domestic waste-water.
b) Domestic waste-water with a high proportion of inorganic content substances from a dairy.
c) The typical properties of municipal waste-water.
d) A big amount of storm water and a very little domestic wastewater.
e) A big amount of groundwater and precipitation water mixed altogether with 20 % domestic waste-water

Task 3: Nitrogen is present in wastewater in different forms and compounds. Which of the listed ‘parameters’ is a pure organic composition?

a) Kjeldahl nitrogen (TKN)
b) Amino acid
c) Uric acid (C5H4N4 = O3)
d) Total nitrogen (totalN)
e) Nitrogen in total (Ntot)

Task 4: As infiltration water one designates the inflow into the sewer system of:

a) Damaging commercial or industrial waste-water.
b) Unapproved connections.
c) Water that runs in from roof and courtyard surfaces.
d) Groundwater that penetrates via leaks and drains.
e) Flushing water that is used for sewer cleaning.

Task 5: A dry weather inflow (Qdw) is 100 litres/s. In this there is an infiltration component (Qinf) of 30 %.

a) How many m3 is the infiltration water inflow per day?

b) What persuade has a higher infiltration water component on the operation of the waste-water treatment plant?

Task 6: The quantity of wastewater flowing from a combined system to a waste-water treatment plant with 100,000 inhabitants can be taken from the given diagram.

a) How big is the quantity of dry weather water?

b) According to the diagram, how much water can the plant accept as a maximum?

c) How big is the specific wastewater component (m3/(I x d)) of this waste-water treatment plant?

d) Why does this value deviate from the mean specific water consumption (m3/(I x d))?
