Problems solved by technology

The use of large-capacity feedback vessels has the disadvantage of having to jettison large tank volumes over the weekend
Large volumes in the filter unit lead to increased heat radiation and reduced availability as the alkaline tank of the bottle washer needs to be filled while the filter system is in operation, which means long downtime during filling time

Embodiment Construction

[0027] According to the invention, a washable coarse filter such as a disc filter 2 is combined with a cross-flow filter 3 for the treatment of contaminated cleaning liquids occurring in breweries.

[0028] For example, a disc filter is shown in Figures 2a and 2b. The disc filter comprises a filter housing 20 as well as a raw liquid supply 21 and a crude filtrate outlet 22 . According to the present invention, the cleaning liquid is supplied to the disc filter 2 through the supply unit 21 . The disc filter 2 comprises a plurality of filter discs 17 arranged one above the other. As can be seen from FIG. 2b, the filter disk 17 is designed as a filter ring. The filter discs 17 are pressed together by the elastic force of the spring 19 . The filter disc comprises ribs 18 on at least one side. Preferably, the groove or ridge 18 extends substantially radially outwards. The ribs of the stacked discs 17 thus form filter holes through which unfiltered liquid passes through the fil...

Abstract

The invention relates to an improved device and a method for processing cleaning fluids, the device comprising: at least one flushable coarse filter for coarsely filtering the cleaning fluid, a cross-flow filter for finely filtering the coarse filtrate from the at least one coarse filter, a return line through which the coarse filtrate is fed through the cross-flow filter in a circuit, a flushingdevice for flushing the coarse filter, a drain branching off from the circuit and connected to the flushing device for flushing the coarse filter with the coarse filtrate fed through the cross-flow filter in the circuit.

Description

technical field [0001] The present invention relates to a method and a device for the treatment of cleaning liquids which occur especially during the cleaning of bottles or in CIP systems, for example in the cleaning of brewhouses in breweries. [0002] However, the method according to the invention and the device according to the invention are also particularly suitable for cleaning fluids present in the food processing industry, pharmaceutical companies or plastics recycling companies. Background technique [0003] In breweries, the cleaning of brewing vessels is done with alkaline solutions just like bottle cleaning. As shown generally schematically in FIG. 3 , the bottles are cleaned, for example, by means of a bottle cleaning system. As will be described in detail below, such a bottle cleaning system 10 includes, for example, a front lye tank 32 , a main lye tank 28 and a rear lye tank 37 as a first rinsing zone. However, in bottle washing, as the amount of sludge dep...
