Page: Acid capacity and organic acids
mmol/l\ and \mg/l\ The acid capacity or alkalinity is a measure of the buffering capacity of the water. It is an important parameter especially for operating digestion rebwp8:Sludge digestion (anaerobic) tanks. It is determined by titration of 550 ml of filtered sample with 0.1 M ...

Page: BOD5
mg O{}2/l\ Biochemical Oxygen Demand means the amount of O{}2 which is needed by micro\organisms rebwp8:Organisms in the waste water to degrade waste water substances at 20°C within 5 days. In order to prevent O ...

Page: Carbondioxide in digestion gas
volume\ The CO{}2 concentration in the digestion rebwp8:Sludge digestion (anaerobic) gas is a measure of the stability of the digestion rebwp8:Sludge digestion (anaerobic) . It can be determined with a CO{}2 analyser, with a certain volume of digestion rebwp8:Sludge digestion (anaerobic) gas ...

Page: pH value in waste water treatment
Biological purification proceeds best at pH 6.88.0. The pH value affects: solubility (NH{}4{}), corrosivity, biological activity and species composition. It can be determined simply with indicator paper or a pH meter

Page: Putrescibility (hydrogen sulphide test)
time\ In putrid waste water H{}2{}S is produced. If it comes into contact with lead acetate paper, the latter turns black owing to formation of PbS. The test is used to determine whether putrid waste water is arriving from the sewer system rebwp8 ...
