Chemical parameters of the water can not only be measured using digital equipment, but there is also a water quality measurement method using titration methods or staining. Here below is the equipment used in the measurement of water quality parameters by titration can be seen in Table 17. Table 18. Equipment used for the measurement of water quality by titration

Alkalinity is a total concentration of alkaline elements contained in water and commonly expressed in mg / liter or the equivalent of calcium carbonate (CaCO3). It is said that the alkalinity in freshwater very important role because alkalinity is not only a direct effect on the growth of plankton, but also affects other parameters. Alkalinity is the capacity of water ...

For water quality monitoring, sampling time interval is set on a different day and time, so it can be differences in the quality of water every day and every hour. For example, if the first sampling is done on Monday at 06.00, then the sampling is then performed on Tuesday at 07.00, etc. Frequency of sampling The frequency of sampling ...
