Problem Solved for a customer in the nuclear sector

When we took over the Water Treatment contract at a nuclear site in the north of England, we reviewed the existing non-oxidising biocide dosing arrangements across the cooling towers.

We identified that biocide was being dosed over a 60 minute period, with the system bleed remaining operational throughout. This meant chemical could potentially be lost before the required treatment concentration was achieved, reducing effective contact time and potentially compromising microbiological control.

As part of introducing our own biocide programme, we optimised the dosing arrangements, reducing the dosing period from 60 minutes to approximately 6 minutes to achieve the required treatment concentration more rapidly.

Importantly, we also introduced an automated bleed lockout, preventing chemical losses during dosing and maintaining the lockout for the required contact period before normal bleed control resumes.

Since implementing these changes, dipslide results have been consistently good, demonstrating effective microbiological control.

Effective water treatment isn’t just about selecting the right chemicals, it’s about ensuring they’re applied correctly.

By reviewing the existing treatment arrangements and making some relatively simple changes, we’ve improved control over the process and reduced the risk of ineffective biocide application.

Another Problem Solved,  and a great example of how we minimise risk, deliver compliance, and make it simple!
