| 摘要 |
The invention relates to a filtration system (10) for liquid, particularly raw water, comprising at least one filtration module (20) for filtering the liquid, a first inlet pipe (21) for feeding liquid to the filtration module (20), a second inlet pipe (22) for feeding liquid to the filtration module (20) and at least one outlet pipe (26) for discharging filtrate from the filtration module (20). A cleaning branch (80) is arranged between the first inlet pipe (21) and the second inlet pipe (22), and at least one dosing feeder (81, 82, 83) for adding a cleaning chemical is connected to the cleaning branch (80). The invention also relates to a method for chemical rinsing a filtration system (10) for liquid, particularly raw water, comprising at least one filtration module (20) for filtering the liquid, a first inlet pipe (21) for feeding liquid to the filtration module (20), a second inlet pipe (22) for feeding liquid to the filtration module (20) and at least one outlet pipe (26) for discharging filtrate from the filtration module (20). In chemically rinsing operation, a cleaning chemical is added via a dosing feeder (81, 82, 83) connected to a cleaning branch (80) which is arranged between the first inlet pipe (21) and the second inlet pipe (22). |
