E-CIP Concept: The Idea and the Solution

The idea for the E-CIP Concept’s design and process arose from the well-known problems surrounding recycled water tanks in traditional CIP systems:

The water quality in the recycled water tank deteriorates over time, which requires regular CIP of this tank. There can be several reasons for this:

1. The tank is continuously supplied with rinse water from the CIP cleaning of all objects in a production plant. If the cleaning of one object has been insufficient, organic residue and microorganisms are carried back to the recycled water tank, where contamination occurs.
2. The water in the recycled water tank is often at a temperature where microorganisms have good growth conditions.

3. For CIP of the recycled water tank, it must first be emptied. Large amounts of water are often dumped into wastewater in this connection. At least one CIP line is blocked during the time it takes to empty and clean this tank. During this time, all water for pre-rinse, for other CIP lines, comes from the fresh water tank. Likewise, there is of course no collection from the lines that are in operation at the time in question.

4. Over time, it is impossible to control the level in the recycled water tank. It is most often completely full.

5. The clean water that the CIP-Return line contains after each CIP is not reused, but is drained in connection with the pre-rinse at the next CIP.

The new CIP concept has been developed based on the above problems, observed through many years of experience with commissioning and optimizing CIP systems and hygienic process systems.

The solution and advantages of using the E-CIP Concept are:

1. There is one collection water tank per CIP line.
2. It is proven that the quality of the pre-rinse water is of a higher quality than with regular CIP.
3. The risk of cross-contamination due to poor water quality in the traditional recycled water tank is eliminated. No recycled water is kept longer than the period between two CIPs.
4. It is easier to troubleshoot if challenges arise with cleaning, as this will quickly be reflected in the quality of the collected final rinse water.
5. The collection water tank can be cleaned at the same time as cleaning the object, which increases flexibility.
