One of the sources from which drinking water is obtained is groundwater. To ensure reliable monitoring of drinking water various parameters are measured and monitored. One of the most important parameters is the pH value.
Flocculation is a process in the treatment of drinking water. It reduces any existing turbidity, which is when extremely fine particles in the water coagulate. As well as the turbidity, the level and flow of the contents in the flocculation plant have to be measured and monitored.
The solid matter and turbidities that form as a result of the flocculation can be isolated through sedimentation. In this process, the water quality is monitored by checking the conductivity and pH value. If the pH value is optimized for the flocculation of organic and non-organic materials, it is readjusted following the flocculation separation and before filtration.
Filtration describes the process whereby a solid matter/liquid mixture in the water or wastewater can be separated or segregated by filters. For the filtration to be efficient, it is necessary to monitor the pressure upstream and downstream of the filter.
Disinfection removes microorganisms from the water by killing them. Chlorine is the most commonly used disinfectant for treating drinking water. Following the proviso "as much as necessary, but as little as possible", the concentration and the chlorine content dosage have to be monitored constantly.
The treated drinking water is stored in storage tanks. The level in these tanks requires constant monitoring. After all, the tanks should be neither empty nor overflowing, but instead ensure that there is an effective supply of drinking water.
