Translation of "Spülverfahren" in English

Compared to conventional rinsing methods, they lead to a considerably better cleaning result.

The invention also comprises an expedient rinsing method.

Rinse Procedure: 500 ml (sterile physiological saline solution) x 60 seconds.

This is also called a stationary washing process in practice.

Such known flushing methods, however, are time-consuming.

The inventive flushing method was applied as follows with respect to the described filter:

Further, the liquid consumption in known flushing methods is extremely high.

In this regard, it may be expedient when the metal components separated off are subsequently subjected to a rinsing operation.

It is also possible, with the purging process according to the invention, for oxygen uptake during the subsequent filling to be substantially reduced.

It is especially preferred if the sediment deposits are taken up by dredging or flushing processes and optionally transported by a suction pump.

Within the framework of this research project there will be a detailed investigation and assassement about different flushing principles and policies.

For this reason the DVGW-research project (W6/01/07) examined the field of application of flushing principles.

If water is added in such a higher proportion that a freely flowable slurry rather than a pulp is formed, the sealing to prevent an inflow of water may be effected in a hydraulic operation and the mixture will subsequently also solidify to form a compact, dense material which is virtually impermeable to water.

The applicants have developed a rinsing process (European Patent Specification No. A80 100 896) which also uses a resting zone which is free of rinsing fluid but in which the maximum quantity of rinsing fluid (fresh water) applied to the textile material is the quantity which the material can carry on entering the resting zone.

SUMMARY OF THE INVENTION The object of the invention is to improve on the aforementioned prior methods and apparatuses and provide a rinsing method of the general type described and achieve an optimum as regards the time taken for the rinsing process, and the quantity of rinsing fluid required.

The back-filling and ground making of the island interior with sand is performed by hydraulic filling methods and/or mechanical filling methods as well as soil compaction methods in accordance with per se known technical rules, wherein the regulations pertaining to shore structures (dykes, harbour installations, navigation lights) have to be observed.

European Patent Application 77 411 describes the use of polyurethane foam lumps as filtration medium, the impurity content of which is washed away from time to time by specific flushing processes to regenerate the foam.

Alternatively to this, use may also be made, over short distances, of so-called drilling or jetting processes in which a tube is introduced horizontally into the ground.

Since the after-dosing of detergent only occurs in the tank where an increased concentration prevails, so that only the volume of secondary component stream flowing into this tank has to be after-dosed, the division ratios fT indicates the factor by which the concentration of detergent in this dosing tank can be increased without any increase in the consumption of detergent over the conventional dishwashing process on which the comparison is based.

Of particular interest in this respect are those cleaning processes which are accompanied by heavy foaming because of the mechanics used and/or the soil to be detached, more especially mechanical cleaning processes, such as spray cleaning or other high-pressure washing or rinsing processes.

Areas of operation include the activation and promotion of the biodegradation of groundwater contaminations in the contaminant plume as well as the active remediation of damage sources with the help of rinsing procedures using alcohols, surfactants or chemical remediation methods.

This rinsing can be effected by spraying or by (if appropriate multiple) dipping into a dipping bath or by combinations of these rinsing processes.

It is especially preferred if the sediment deposits are taken up by dredging or flushing processes and optionally transported by a suction pump.

BRIEF SUMMARY OF THE INVENTION It is thus the object of the present invention to provide a method whereby items to be processed, located in a processing chamber, can be dried effectively and efficiently from an economic perspective so as to keep the energy consumption as low as possible in spite of a very good drying performance.

For changing the component ZK for another component ZK?, for example for a component that differs in taste and/or colour, corresponding to FIG. 3, initially with liquid valve 13 closed, all the flow connections that contain the component ZK used up to then are flushed in a flushing process using a flushing medium, for example water or sterile water, in particular the fluid connection 16, the opened stop valve 18, the metering pump 19 and the line 20 leading to the metering pump 19, in so far as they contain the component ZK.
