AW - Model IOT 1000 - 60000 -Ion Exchange Circulation Plant

Principle
Removal of undesired ions from water using an ion exchange procedure with multiple reuse of the transporting water.

Function
Water has to be free of suspended matter and fats or oil, since these can damage the ion exchange resins and impede the process. This usually means an additional cleaning step using active carbon filter. The plant works in ascending flow and regenerates in descending flow, meaning that water flows through the filtration columns from bottom to top, while the regenerating agents (hydrochloric acid and sodium hydroxide solution) flow in from top to bottom.

Depending on the use case, the plant work in parallel or serial mode. It is controlled by a conductivity meter in the ion exchanger discharge. If the desired maximum demineralization value is exceeded, (between 30 – 40  µS/cm  depending on use case), the plant has to be regenerated. The plant should not be overloaded to prevent damage to the exchange resins and reduction of pure water quality.

Installation
The plant is delivered in compact form, mounted on a steel rack and ready for connection. On site, the lead connections (city water, pressured air), chemicals, connection for pure water, discharge connection and electrical connection have to be created.
