T ransvac has developed a simple way of adding PAC into the raw water supply. The system doses the exact amount required to remove the pesticide without the need for large batch mixing tanks and multiple pumps. A compact packaged system called TransPAC has been developed to include a bulk bag handling frame, carbon transfer equipment, booster pump, header tank, control panel and Ejector skid all within a 20• steel shipping container. A simple HMI control panel runs the system with the only input being the flow rate of carbon, set by the operator as required. The system features an automated control sequence that transfers carbon from a half tonne bulk-bag to an intermediate storage hopper which is then dosed at a set rate into a wetting hopper above a custom designed Transvac Ejector. This ejector is designed to take a fixed motive water flow from the booster pump and entrain the carbon slurry, sending it along dosing pipes to the point of application (normally at the Dissolved Air Flotation (DAF) plant inlet). Transvac was able to speed up the completion of the original TransPAC unit and was 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 SUPPORTED BY DRIVING INTEGRATED THINKING IN WATER The 5th annual WWT Integrated Water Resources Management Conference brings together those tasked with the sustainable management of water, land and natural resources to maximise economic, social and environmental welfare. ● Learn how the water industry is implementing the WFD and managing abstraction reform ● Explore how innovative partnerships are transforming the water sector ● Discover how to build resilience to enhance cost-savings and drive sustainability David Black Senior director, Water 2020 Ofwat Jo Harrison Director of asset management United Utilities Tony Ballance Director of strategy and regulation Severn Trent Water Jean Spencer Regulation director Anglian Water Henry Leveson-Gower Head of abstraction and upstream Defra Robin Milton Chairman National Farmers' Union Luke de Vial Head of environment and resources Wessex Water EXPERT SPEAKERS INCLUDE: INTEGRATED WATER RESOURCES MANAGEMENT CONFERENCE 14 SEPTEMBER 2016 | BIRMINGHAM SUPPORTED BY FOLLOW US @WWTlive #suswater UK Rainwater Management Association 5 TH ANNUAL BOOK NOW www.WWT-environment.net WWT-IWRM-brochure.indd 1 24/03/2016 12:34 A solution: Compact packaged dosing on the same day. As soon as water, a dosing line and power were 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 a•er delivery to commission the TransPAC, including providing onsite training for the treatment works' engineers. Once this was completed the site could start dosing carbon to remove the taste and odour issue. Carbon footprint 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 multimillion-pound GAC plants, which can take years to design and build. A digital HDMI panel meant 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, making it suitable for tackling changing conditions across multiple sites In fact, the water company has already ordered another TransPAC, which will swap places with this unit, and the first TransPAC will then be relocated back to its original destination, re-figured to dose to the new taste and odour levels and immediately start dosing.
