Chlorine Gas Replacement

November 2018 update –

As part of Yorkshire Water’s drive to become ‘Gas Free’, the R1140 Gas Replacement programme achieved a significant milestone when Loftsome Bridge (a 110Ml/day water treatment facility) switched to Sodium Hydrochlorite, after traditionally using Chlorine Gas disinfection.

This was achieved by using one of our Mobile Dosing Systems as a temporary installation. The system has been designed, manufactured, installed and commissioned by LEADA Engineering Ltd as part of the ongoing Gas Replacement Programme for Yorkshire Water.

This temporary installation allowed the decommissioning of an existing Chlorine Gas System in order to make the site completely ‘Gas Free’. After successfully commissioning the Temporary Dosing System, the installation of the permanent disinfection system can now be progressed, re-using the existing infrastructure, allowing capital efficiencies to Yorkshire Water and best value to their customers.

The innovative Mobile Dosing Trailers are currently in use, supporting Yorkshire Water to maintain supply at 5 treatment facility across the region while permanent installations are being implemented.

We are currently working with Aceom & Galliford Try ( AGT ) across Yorkshire and the Humber to remove Chlorine gas from various sites. On this project, we’ve been involved with the design, decommissioning and commissioning, as well as the installation of Bulk Sodium Hypochlorite Dosing.

* Chlorine gas has been isolated and made ‘Gas Safe’ at East Ness WTW On 19 Feb 2018
* The Temporary Sodium Hypochlorite Dosing Trailer and associated equipment has been in continuous service since 01 February 2018 without issue.
* The system was commissioned during December 2017
* The Temporary Dosing System is fully automatic with duty/standby dosing pumps and integrated with YWS site control facilities.
* This will allow the gas facilities to be removed from the site to make space for the permanent equipment to be installed.
