Ecolab uses mixed reality to troubleshoot process water problem at phosphate mine

Ecolab’s Remote Assist program has leveraged mixed-reality technology to overcome COVID-19 restrictions and provide critical, speedy customer support to a mining company in the Middle East.

The company, a customer of Nalco Water, an Ecolab company, was suffering from an unknown mechanical issue, which impacted chemical dosing for process water treatment. As a result, the phosphate mine was facing a potentially costly disruption of its activities.

“Not too long ago, the mine’s remote location of approximately 1,400 km away from the nearest technician might have led to operations being curtailed for several days,” Ecolab said. “Challenges created by the pandemic further hindering the technician’s ability to travel could have made the outcome even more bleak. However, by leveraging mixed-reality tools that combine elements of virtual reality and augmented reality to create a blend of the physical and digital world – in this case, a hands-free tablet-class wearable computer – Ecolab’s mining division was able to come to the rescue in a timeframe that would have been unthinkable just a few short years ago.”

Connecting with a senior engineer at the treatment plant, the Nalco Water technician was able to communicate in real time, inspecting the equipment to gain an understanding of the operational challenges on site. Safely working together in a virtual environment, the two associates were able to quickly diagnose the issue and replace the component that was ultimately behind the problem.

“Service that would otherwise have required two days of travel was completed in just one hour, saving travel costs, maintaining social distancing and reducing the carbon footprint,” Ecolab said.

As well as offering mining and mineral processing programs that combine chemistry, automation and control technology to help plants optimise production, Nalco Water’s proprietary 3D TRASAR™ smart water treatment system has enabled the company to offer the benefits of remote monitoring and troubleshooting on over 40,000 units installed worldwide, Ecolab said.

Arjan Boogaards, Senior Vice President and General Manager, Global Mining & Mineral Processing, Nalco Water, said: “We have greatly optimised productivity for our customers with these innovations, but, inevitably, the occasional mechanical issue will call for service and support that is outside of the scope of smart controllers and automation on site. That’s where we can apply mixed-reality technology and continue to transform the future of service and support by enabling expedient, accessible issue resolution. We can help connect our customers to a global infrastructure of research, innovation, engineering and digital experts in a faster and more efficient way.”

Ecolab’s Remote Assist program incorporates mobile applications that can connect to a remote collaborator. Through live video calling, annotations and sharing high-resolution snapshots with the remote collaborator, users can co-operate to troubleshoot problems quickly, according to the company.

Use of the latest mixed-reality technology enables Ecolab to gain remote access to its customers’ facilities in several beneficial ways. Its sales and technical representatives in the field can wear mixed reality devices for a “digital focus first, real-world focus second” approach to basic digital training in safe environments, Ecolab said.

Mixed reality also enables them to virtually connect to Ecolab’s scientists, engineers and cross-functional teams for support. This enables them to remotely diagnose and troubleshoot issues around contamination, oversee chemistry usage, guide the installation of new equipment, monitor water and process conditions and, ultimately, implement solutions that maximise customer productivity.

“This is most definitely an approach both we and our clients will continue with, even after COVID-19 has become a bad memory,” Boogaards said. “The pandemic has sped up the process for many companies to adopt digital tools, and they are dramatically improving their operations. The time and money savings are undeniable, so companies that do not make use of these tools could place themselves at a competitive disadvantage. We’re clearly entering a new era.”

IPR’s SlurrySucker tackles seawater and sediment at South Africa mine

Integrated Pump Rental’s SlurrySucker dredging unit recently came to the rescue of a mine on South Africa’s west coast suffering from sea water ingress into its main process water pond.

A recent two-week trial saw the SlurrySucker take on saltwater and high-volume conditions at the mine.

The mine’s main process water pond would fill with sediment within a week, with the sea water it was filled with being highly corrosive, according to IPR. In addition to dealing with this problem, the mine wanted a safer and more cost-effective option than the divers, equipped with manually operated suction pipes, it was employing to remove sediment.

Ruaan Venter, Rental Development Manager at Integrated Pump Rental, said: “This large pond – about 70 m square and 8 m deep – is central to the mine operation as it feeds all the process plants. It is therefore vital that sediment is removed continuously, quickly and in large quantities.”

During the trial, the SlurrySucker was able to pump 250 cu.m/h of sediment with a solids content of 30-40%. This allowed the specialised dredging equipment to remove 60-70 t/h of sediment from the pond.

“When in contact with conventional metal pump components, saltwater is extremely corrosive and, over time, can cause a lot of damage to the equipment leading to the frequent replacement of wear plates and impellers. In addition, the integrity of the framework will also be compromised,” Venter said. “Under these conditions and to mitigate against corrosion, we provide our customers with a full stainless steel pump solution with rubber-lined pipes to transport material from the pond.”

The success of the trial has raised the interest of other mining operations along this coastline, where sea water is also used in the process plants, according to the company.

“Demanding conditions like these would warrant the customer considering a purchase option,” Venter says.

“It is likely that the SlurrySucker would be operational every day on these ponds, making this specialised equipment a valuable investment in the efficient running of the plant.”
