Visiting our valued clients to discuss upgrading a water treatment plant is always an interesting experience, but often the importance of addressing peripheral requirements needs to be highlighted.
Below, we discuss a classic example of a client wishing to upgrade a water treatment plant but found they had to firstly overcome water hammer issues.
When recently inspecting a Granular Activated Carbon (GAC) water filtration system for a soft drink manufacturer, our technician noticed sudden pipe vibrations and leaking filters.
In this application the mains water supply is pressurised through an activated carbon filtration system to remove chlorine, and then is fed to the process lines, a common step for beverage producers.
The site technician discovered that each time the downstream actuated valves changed position, the resultant water hammer caused costly downtime to production, due to the need to fix up leaks and failed cartridge filter pipework.

If it’s not possible to eliminate the causes of water hammer you can still reduce the effects by taking the following actions:
