A global pharmaceutical instrument and system manufacturer, located in Northern India, required consistent high purity, pharmaceutical grade water for their process. The process scheme chosen to
produce high purity water consisted of a softener, a reverse osmosis system and an electrodeionization (EDI) unit as the nal polisher to achieve the desired water conductivity.
The client’s existing electrodeionization system, with another manufacturer’s EDI, was not able to
deliver the desired product water quality, below 1 S/cm. This was due to variable feed water conditions, primarily due to presence of CO in the water. As a result, their production was adversely a ffected and the client faced a shutdown. Service also became a key issue as the customer was not satisfi ed with the existing EDI manufacturer’s support.
They urgently started exploring other EDI options, with the least lead time for delivery. They expected the EDI supplier to understand the problem and work closely with them to resolve the quality concerns at the earliest possible.
