A method and apparatus for filtering, especially for filtering beer, in which a filter having an inlet and an outlet has the outlet connected with the conduit system leading to first and second tanks and to drain. The filter is flushed with water periodically and a control system is provided which senses the density of the fluid at the filter outlet and controls valves in the conduit system. The control of the valves provides for diverting fluid from the filter outlet from a first beer storage tank to an intermediate tank when the density of the fluid at the filter outlet is modified by water and then from the second tank to drain when the density of the fluid at the filter outlet stabilizes. In returning to beer filtration, the fluid at the filter outlet is supplied to the drain until the density is substantially modified by beer at which time the fluid is diverted to the aforementioned second tank and thereafter, when the density of the fluid of the filter outlet stabilizes, the filter outlet is again connected to the beer storage tank.
The method of operating a filtering system which includes a filter having a fluid inlet and a fluid outlet, a first receiving tank, a second receiving tank, a drain connection and valved conduits connecting the filter outlet with said tanks and said drain connection, said method comprising;
A filter system which includes a filter having a fluid inlet and a fluid outlet, a first tank having an inlet, a second tank also having an inlet and a drain connection;
A filter system which includes a filter having a fluid inlet and a fluid outlet, a first tank having an inlet, a second tank also having an inlet and a drain connection;
