Abstract
A system for filtering liquids like cooling water and emergency cooling water in nuclear power stations and other industrial plants wherein a continuous circulation of a coolant or other liquid has to be secured. The system comprises a first filtering surface and a first filtrate space which is at least partially limited by the first filtering surface and at least one further filtering surface with a second filtrate space which is at least partially limited by a filtering surface. A filtrate outlet channel is connected to the first filtrate space and a siphon connects the filtrate spaces.

A filtering system for filtering liquids in plants where a continuous flow of liquid through the filtering system has to be secured, the system comprising:
- a first filtering surface,
- a first filtrate space which is at least partially limited by the first filtering surface,
- at least one further filtering surface,
- at least one further filtrate space which is at least partially limited by a filtering surface,
- a filtrate outlet channel connected to the first filtrate space, and
- at least one siphon connecting two of the filtrate spaces, the number of siphons being sufficient to connect the spaces pairwise so that each space is connected to at least an other space through a siphon.
A filtering system for filtering liquids in plants where a continuous flow of liquid through the filtering system has to be secured, the system comprising:
- a first filtering surface,
- a first filtrate space which is at least partially limited by the first filtering surface,
- a second filtering surfaces having different permeability to the filtered liquid than the first surface,
- second filtrate space which is at least partially limited by the second filtering surface,
- a filtrate outlet channel connected to the first filtrate space, and
- a siphon connecting the filtrate spaces.
