The benefits of the Type 8905 for drinking water analysis

The Type 8905 Online Analysis System from Bürkert is a multi-parameter device that offers UK water companies a modular and multi-functional drinking water analysis solution in one compact and intelligent system. Greg Wainhouse, our Industry Manager for water at Bürkert, explains why the Type 8905’s remote cleaning and maintenance functionality could be particularly attractive to the Water industry.   

Analyse drinking water parameters with the Type 8905

Type 8905 Online Analysis System is a compact and modular system for monitoring all important drinking water parameters on one platform. This multichannel, multifunction unit is designed for use with Bürkert sensor cubes and electronic modules that utilise our efficient device integration platform (EDIP) platform. EDIP delivers greater flexibility thanks to modularity in the hardware and in the software of the system.

The Type 8905 Online Analysis System offers continuous measurement of drinking water quality parameters, with up to six measurements in one housing, including pH-value, chlorine, conductivity, ORP-value, turbidity and chlorine dioxide. All of these analysis functions are available in one easy to install and operate system. ‘Hot swap’ functionality enables users to add or remove up to 60 analysis sensor cubes in one büS system without interrupting operations.

While the standard housing can accommodate up to six sensors, thanks to our Efficient Device Integration Platform (EDIP) and the Type 8905’s modular plug and play design, larger panel-based systems can be developed to provide flexibility to monitor multiple sample lines on one büS network. Ultimately, end users can enjoy more features and greater performance for less capital expenditure.

Remote maintenance for water analysis applications

Prepared for fieldbus connectivity, one of the major selling points of the Type 8905 Online Analysis System is the fact that it can be calibrated to carry out remote maintenance. “The water industry relies on having people onsite to clean and calibrate devices”, says Greg Wainhouse, Field Segment Manager for .water at Bürkert. “However, with the Type 8905 we can get the system to clean itself. It can either be set on a timed basis or you can manually trigger it.

“It depends on what type of system water companies would be using but, as a general rule of thumb, this sort of thing will normally be done manually. This typically involves shutting down the line, removing it and manually cleaning it. There are some sensors on the market that have utilised mechanical devices, such as spray heads or wiper blades, which could fail and can’t be easily maintained or repaired.” All of which can be easily mitigated by opting for the multi-functional Type 8905 Online Analysis System from Bürkert.

With the Type 8905 you don’t have to carry out any manual cleaning or intervention, which reduces downtime and can even streamline onsite staffing requirements. Greg continues, “Cleaning can either be done automatically or you can trigger it remotely. That therefore reduces the number of personnel on site, which is a big advantage. It also saves time because it can be done from behind a desk – you don’t have to go out to the plant to do it.”

The next step in drinking water analysis?

After an initial calibration, The Bürkert Type 8905 empowers users to carry out remote cleaning of their system – something that has made the water industry sit up and take note according to Greg. “With our system you can trigger a cleaning system remotely,” he says. All of which makes the Type 8905 Online Analysis System an interesting proposition for UK water companies who are continuously in pursuit of greater efficiencies form their water analysis processes.

“We haven’t yet actively promoted the Type 8905 to UK water companies,” he adds. “However, we have had quite a bit of interest and we have our first device going out on trial this summer. We’re also delivering a lunch and learn with a water authority later in the year. Plus, we’re involved with the Sensors for Water Interest Group (SWIG) and have delivered several table top presentations. As such, the Type 8905 it is generating interest and turning heads in the industry.

“We also have more analytical sensors in development, which we hope to launch very soon,” Greg concludes.
