If acidic and alkaline rinsing water is produced during production, for example from cleaning production facilities, it must be neutralized before being discharged into the sewage system. In this way, acidic rinse water is often neutralized with fresh lye and alkaline rinse water with fresh acid
Better with the AGW loop reactor concept: the discharged wastewater flows are first temporarily stored as acidic and alkaline water, combined in the AGW loop reactor and neutralized with each other.
As the AGW loop reactor has a much smaller volume than a classic reaction tank, the pH value can be adjusted more quickly and more precisely by adding wastewater in a controlled manner. This procedure drastically reduces the consumption of fresh chemicals.
More concentrated waste water is used specifically for neutralization. Fresh chemicals are only dosed if they are not available. The AGW loop reactor is suitable for
- Water with a low metal load
- Water with a low solids content
- Acidic and alkaline rinsing water
Advantages of the AGW loop reactor:
- Fresh chemical savings of approx. 80 % depending on the application
- Space-saving design
- different wastewaters can be neutralized together
- more flexible operation of the AGW loop reactor due to lower buffer volume compared to continuous neutralization.
