Norwich, UK -- Every year Severn Trent Water hosts a two day supply chain event, Quality Working Day. Lintott Control Systems took part on the day. The annual event is organized by Severn Trent Water to promote projects and supply teams which have delivered exceptional standards in their relative disciplines.
Lintott are currently working on a Framework Agreement with Severn Trent Water on the design and delivery of its Fluoridation Project for the supply of packaged modular designed chemical dosing systems to a number of locations across the region.
During the exhibition the approach won two of the three awards it was entered for, a Gold award for collaborative working and a Bronze award for Highest Standards. The energy and the passion that the whole team showed during the two days was self evident. It was felt that everyone who came to our stand was engaged at some level either with the game or the content on the stand.
The Fluoride dosing equipment which the Strategic Health Authority is located in the region has come to the end of its economical life. Due to the age of the equipment and the changes in operational approach the equipment was not able to be replaced on a like for like basis and required an entire re-engineering and re-assessment of an approach to be standardized for future supply.
Lintott Control Systems developed the approach of packaged chemical dosing systems for Fluoridation specifically to meet the needs of the Strategic Health Authorities (SHA) directive on the fluoridation of public water supplies and also the special requirements of handling chemicals such as Hexafluorosilisilic Acid (HSFA).
As part of our contract we engaged both the Strategic Health Authority and Severn Trent Water to develop a Packaged Plant solution which met both organizations standards and requirements. Due to the exceptionally aggressive nature of the chemical on materials and the imposed health risks Lintott developed a design which offered level of equipment segregation and integrity that far exceeded anything that had previously been supplied to the Severn Trent Water region.
As a development and prototyping project, prior to the letting of a contract for the supply of a further 24 sites, Lintott Control systems engaged with engineers and operators over an 18 month period and developed a solution which has been adopted as an industry leading standard.
The innovative solution provided by Lintott for the development of package chemical dosing systems has led to a review in the code of practice to provide improved guidance to the UK for the correct methods of handling and storing HSFA for public water supplies.
Equipment developed by Lintott utilized a 4M wide by 4M High x 10M long re-enforced GRP kiosk with specialist resin the prevent the attack of acid onto the glass construction. The equipment was then divided into thee distinct area’s covering Control, Dosing and Bulk Storage. The control section was fitted with a Lintott’s Control System and Lintott Software in an entirely sealed room to protect the equipment from any potential fume or liquid attack. Because of the implicit risks to public health in the event of chemical overdosing Lintott designed, supplied and installed control and software system to SIL1 standards, incorporating hardwired safety shutdown systems monitored on several layers.
The control system incorporated and Allen Bradley control logics PLC and a panel view plus 1000 HMI. The software was produced using Severn Trent Water function block libraries and graphics, although due to the SIL rating Lintott Control System was required to develop a solution to enable the PLC to have an additional protected area of the software code that monitors the PLC internal system safety shutdowns. This protected area of the PLC is isolated from general PLC access by a second layer of security.
The HMI also contained full trending, manual control and status monitoring facilities.
The dosing room contains Duty/Standby Dosing and Transfer pumps in fully segregated polypropylene dosing skids. Adjacent the to dosing room is the bulk storage facility which houses bulk storage chemical tank, day tank and product overflow waste tank, all built to BS EN 12573 and located in a 110% bund. The whole system is serviced by forced ventilation and extraction to ensure chemical fumes are not able to build up over time. All pipework is PVDF and exotic metals where metallic components are used.
As the equipment is packed Lintott were able to offer equipment built off site and, fully tested and ready for installation in a 16 week period. By the use of innovative production line techniques and 3D modelling Lintott Control System ensured that the time sensitive program did not have an adverse affect on quality and also provided system standardization with its increased commercial and HSE benefits.
Lintott Control Systems success in the chemical dosing market is attributed to their highly trained and experienced staffs that develop solutions in MCC and Control Panels, Software and Process Mechanical Engineering disciplines. All functions are required to operate the chemical dosing plant in the most efficient and safe method.
