For the Ice Pigging™ cleaning service, tankers of ice slurry are transported to a customers’ site to undertake one off or periodic cleaning. The SUEZ team of Ice Pigging™ experts have applied this technique to a wide range of pipe networks in sectors such as water, wastewater, industry, and oil & gas.
The delivery equipment ranges in size from two to 15 tons, with a maximum single delivery of 35 tons. This is suitable for cleaning up to 5km of pipework in a single operation. Longer networks can be broken into shorter sections and be cleaned by a scheduled programme of operations.
The service delivery team is based in Bristol and from here they can deliver projects throughout the UK and Northern Europe. For projects further afield, there is a mobile ice generation plant which can supply 10 tons of ice per day. Under licence, Ice Pigging™ cleaning services are offered in other countries.
Before any work starts on site, the SUEZ team work closely with the client to create an effective and efficient cleaning plan. This will break the pipe network into individual operations utilising existing fittings wherever possible and will focus on minimising disruption or any other factors important to the client.
The quantity and consistency of the ice is bespoke to the individual requirements of each application. During the operation, the progress of the Ice Pig™ is monitored in real-time by the Flow Analysis System which collects data for temperature, flow rate, conductivity, pressure and turbidity.
Depending on the nature of the waste produced, it can either be collected in waste tankers or discharged to the local sewerage network.
With two patents for the technology, Ice Pigging™ requires a level of expertise and skill that cannot be found outside of SUEZ. Involved with Ice Pigging™ from its commercial beginnings and with over 90 years of Ice Pigging™ experience between them, our team of Ice Pigging™ operating specialists and engineers have unparalleled expertise in cleaning pipes with ice.
The Ice Pigging™ approach has significantly improved the speed and standard of clean. The customer has now adopted this for their hardware cleaning programme and purchasing two customised machines to be installed at their facility.
We thought this pipe was uncleanable, in part because it was so inaccessible, but Ice Pigging™ worked. We are really impressed with the standard of work, level of professionalism and all round well done for the job
Ice Pigging™ has proved to be a ‘game changer’ for us. Ice Pigging™ has now been adopted for other production sites
SUEZ did a great job in allowing us to deliver our project on time. The Ice Pigging™ equipment was new to us, SUEZ recognised this and made our project run smoothly by explaining at the right level of detail at each stage, from equipment specification right the way through to shipping and delivery. Communications with the SUEZ team were always open and easy, they listened to our requirements, enabling them to understand the detailed specifications and timelines that were required. I look forward to working with SUEZ and Ice Pigging™ again on the next project
The ease of the operation and the way the team went about it and how efficient you were was really impressive and it was nice to see some thought going into the whole process rather than just sending the ice down and hoping for the best.
Ice Pigging™ is a brilliant concept of special pipe cleaning problems. Not only removing sediment but also removing the bio-film! After Ice Pigging™, the PVC pipes we had pigged looked like new inside
We were delighted and relieved that Ice Pigging™ very successfully removed biofilm from our ultra-pure water loops
A 100% improvement in flow rates due to a build-up of abattoir waste on the pipe wall. Ice Pigging™ saved £2000 a day in contracted waste tankers.
The pipe was cleaned over two nights with the main isolated for only 6 hours in total, resulting in no customer disruption and over 323kg of material removed from the two sections. Ice Pigging™ has allowed the company to reverse flows in a pipe which previously, would have been impossible at such short notice.
As an engineer myself I was very interested and involved in the project and could see the benefits of Ice Pigging™ straight away compared to traditional pigging systems. Ice Pigging™ technology has great potential.
