| 摘要 |
The invention relates to a device for filtering water, comprising a filter arrangement with a chemical-free self-cleaning function for cleaning the filter, as well as an ozonation device. To achieve advantageous filtration ratios, a supply line (1) for contaminated water is connected to the pump (7), and the ozone supply line (6) of an ozone source, particularly an ozone generator (5), is connected to said supply line (1) so as to supply ozone to the contaminated water, said pump (7) supplying ozonated water to a filter module (8), particularly to a crossflow ultra-filtration module, and purified water flowing into an outlet (9) on one side and into a container (10) for clean drinking water on the other side, said container (10) being connected to the filter module by means of lines and a cleaning return pump (11) in order to counter-flush the filter membranes in the filter module (8), and contaminants retained in said filter module (8) being flushed out by means of a pressure-regulator device (14), particularly a valve, that is associated with a wastewater outlet (15). |
