Meet our new Senior Water Treatment Engineer, Roger Darlison

We’re constantly looking for experienced engineers to join our team at Excel, particularly when they bring specialist expertise with them. Roger is the newest Senior Water Treatment Engineer to join our team and will be providing customers with Continuous Electronic Dionisation systems.

CEDI technology enables the highest quality of pure water to be generated for manufacturing processes. The process doesn’t rely on harsh chemicals and provides increased water savings when compared with other methods.

We caught up with Roger to find out a bit more about the new service and his experience within the industry.

Roger, please tell us a bit about your background

I have spent most of my working life as a service engineer in different fields, and my experience with pharmaceuticals and purified water began around 22 years ago. In the last 12 years, I have entirely specialised in purified water, working my way up from level 1 engineer to managerial level.

What are the main concerns of clients looking to achieve pure water?

Interruption of supply and contamination are huge factors. Companies rely heavily on their purified water for production and any loss of supply can result in loss of revenue. It can be hard to determine the source of bacteriological contamination and even harder to eliminate!

What difference does a CEDI system make for a business?

The removal of harsh chemicals from the purification process is noticeable. Customers comment on how clean and safe the generation system is as opposed to equipment that uses chemicals. The reliability and consistency of the highly purified water generated is another clear benefit.

How has the industry changed over the years?

CEDI technology has improved greatly over the last 10 years. In many instances, a pharmaceutical grade system will be designed to incorporate RO and CEDI, rather than Deionisation which uses chemicals. While there will always be instances where Deionisation is preferred, there has been a shift towards incorporating CEDI systems as the preferred purification method.

What is your usual process for surveying and designing a system?

Firstly, we find out what grade of purified water is required. This is followed by gathering usage data and a feed water analysis; giving us the information we need to start the design process. Pharmaceutical customers will often supply us with a URS (User Requirement Specification) which acts as a ‘road map’ to building a system to their exacting requirements.

Do you come across any common misconceptions about Continuous Electronic Dionisation?

Yes, prospective customers can be put off by the initial outlay to install a CEDI system and may believe it’s the more expensive option. However, the installation cost is offset by the relatively low running costs for the life of the product, providing a return on investment.

What appealed to you about working with Excel Water?

With many years’ experience in my industry, working for a small but ambitious company appealed to me. Joining the Excel team gives me a different and exciting challenge every day. I’m looking forward to seeing an Excel Water branded CEDI unit installed on a customer site!

We hope this has provided a bit more information regarding Continuous Electronic Dionisation systems for customers. For advice specific to your business, contact us today on 0113 232 0005 or sales@excelwater.co.uk.
