Urgent WTW issue solved thanks to TransPAC’s flexibility
12 August 2015, News release from Transvac
A TransPAC carbon dosing unit already on order was able to be reconfigured and immediately dispatched to a more urgent issue at a WTW without the need for major changes or disruption.
One of the largest regulated water companies in the UK recently placed an order with Transvac to purchase one of their fully-containerised carbon dosing systems, the TransPAC.
The system was to be delivered to one of their water treatment works to tackle ‘taste and odour’ issues by dosing the exact required amount of Powder Activated Carbon into the water.
However, just a few weeks away from delivery, the same water company experienced more critical taste and odour issues at a different WTW, 60 miles away from the original site. TransPAC units can take up to 12 weeks to manufacture from scratch, and with sales of TransPAC at an all time high, there were no ‘ready made’ units to purchase.
After discussions with the water company, Transvac were able to speed up the completion of the original TransPAC unit and, thanks to it’s unique flexibility and adaptability, were able to send the unit to the more urgent of the two sites. The project required a quick reaction from all teams involved to complete the system manufacturing, testing and commissioning in time to help the site.
In keeping with the urgency of the issue, the unit was collected from Transvac by Hiab lorry and positioned at the site on the same day. As soon as water, a dosing line and power was provided to the unit, the system was ready for testing. To get the site running as quickly as possible, Transvac engineers travelled to site almost immediately after delivery to commission the TransPAC, including providing onsite training for the WTW engineers. Once this was completed the site could start dosing carbon to remove the taste and odour issue.
Unlike installation of traditional Granulated Activated Carbon (GAC) plants, this project did not require any ground or construction works prior to relocation of the unit. This meant the project had a much lower carbon footprint compared to building multi-million pound GAC plants which can take years to design and build.
Thanks to the digital HDMI panel, the TransPAC could be re-figured to suit the exact dosing needs of the new site without having to wait for a new unit to be custom-built. As the TransPAC is fully contained in a shipping container, the whole unit can literally be picked up and delivered elsewhere, perfect for tackling changing conditions across multiple sites! In fact, the water company have already ordered another TransPAC which will swap places with this unit, and the first TransPAC will then be relocated back to it’s original destination, re-figured to dose to the new taste and odour levels and immediately start dosing.
“Transvac’s quick reaction was the key to the success of this project, with priority given to get the system into the WTW where it was needed in more urgently. Due to the TransPAC being so adaptable it was great that we were able to respond to such an urgent issue so quickly. “
