Abstract
A description is given of processes and machines for the treatment of drinking water, preferably in the domestic sector. With these processes and machines, undesirable constituents, for example organic and inorganic substances which are harmful to health, can be removed from the drinking water or microbial contaminations reduced. For this purpose, the technologies of ion exchange, adsorption at surfaces and sterilization by means of UV light are applied. As a result of taking account of the physico-chemical parameters of the water and the various operational states in the regulation of the process, the exhaustion of the filter cartridge is monitored and a change in the quality of the treated water with operating time is avoided. Bacterial contaminations of the water are avoided by advantageous embodiments of the UV sterilization device. Since the feedstock container can accommodate both the water to be treated and also the treated water, a low space requirement results for the treatment machine.
