of time when a project is approaching the handover.” Key communications To integrate these pilot plants with the wider treatment plant, communication is key. The 8653 used in these pilot plants are IO-Link enabled and do not require Communicator to transfer settings. From the outset, RSE had included components that used IO-Link so the Bürkert valve island was able to fit straight in. Once the first plant was configured, the settings could be transferred to the second plant using the IO Master, making set up and commissioning much easier and quicker. Greg concludes: “Bürkert offers a variety of communication protocols on its equipment to cater for the diverse industries we supply. In the case of the municipal water sector, IO-Link is becoming increasingly popular, but it is important to be able to deliver effective communications whatever the preferred protocol is.” Three of the four pilot plants have been delivered and installed. http://www.burkert.co.uk not ideal, but it did offer us the opportunity to compare the two products side-by-side. The first, and most obvious difference, is the size of the original valve island, the Bürkert product is much more compact.” Component size is very important in these projects because space is often limited, especially when you are trying to incorporate an additional process in an existing application. Compact controls make installation easier and quicker. In addition, the fact that the Type 8653 can be specified with either IP65 or IP67 protection, makes it very flexible in terms of location. There is always a concern that design changes will be required to accommodate an alternative component, but in this situation, it was a drop-in replacement, and the time saving was significant. Following a discussion with Bürkert, the precise specification was quickly determined, and the short delivery time brought the pilot project back on schedule. Pneumatic advantages Pneumatically controlled valves, as opposed to electromotive designs were selected primarily because the ceramic membranes need to be periodically backwashed and within the pilot plants is an option for an air flush of the membrane feed channels, using compressed air. This pre-existing resource makes the pneumatic control infrastructure more cost-effective than an electromechanical solution. In addition, the speed of control is also important and pneumatic valves are usually much more reactive than their electromotive counterparts. It was crucial that specific valves within the pilot plants opened and closed within two seconds, any slower and it would cause issues with specific processes. As soon as each pilot plant was delivered, technicians from RSE completed the installation and commissioning processes, which were simplified by the replacement valve island. Greg Wainhouse, UK Industry Account Manager for Water, explains: “When it came to commissioning, the digital display on the Bürkert valve island made the whole process much easier. The information available on the LCD display means that the technicians do not have to be watching the HMI or the PLC display when the valve settings are being configured.
