Dewatering nuclear slurry - no problem

Sediment can be generated everywhere outdoors, created from rainfall run-off from the land which may be augmented with settlement of air-born dust. The process is ubiquitous and requires periodic removal of slurries and sludges from pipes, settlement tanks and other vessels. This is a universal problem and nuclear storage facilities are no different, however, they present their own specific set of challenges for containment of all materials within the perimeter of the site.

Electrokinetic's EKG dewatering bags offered a dewatering and containment solution in one operation. A batch of 50 EKG bags, each with an internal volume of 1 cubic metre, was used to dewater 400 cubic metres of nuclear contaminated sludge. The EKG process raised the solids content from around 8%ds to 44%ds and contained the cake ready for encapsulation and long-term storage.

Used in batches of 3, the bags were filled with slurry and topped up 4 times over a period of 4 days. This resulted in an overall throughput of around 8.3 cubic metres for each bag.

The project was deemed to be highly successful by the dewatering contractor, main works contractor and the site owner.

Congratulations! Stephanie awarded ICE North East fellowship

The Institution of Civil Engineers (ICE) North East, has awarded a fellowship to Electrokinetic director Prof. Stephanie Glendinning.

Fellow is the highest grade of membership of the Institution. It can be awarded to those who are or have been engaged in a position of responsibility in the promotion, planning, design, construction, maintenance or management of important engineering work.

Cost effective dewatering of Coal Authority ochre slurries

Treatment of minewater from abandoned coal mines produces large volumes of iron ochre sludge which has a solids content of around 1 – 3%ds and the consistency of single cream. Conventional methods of dewatering this material are to use either active methods such as centrifugation, which is rapid and effective but expensive, or passive methods such as lagoon drying beds which is less expensive but very slow.

Electrokinetic undertook a project with the Coal Authority to demonstrate that the application of EKG materials and methods to a settlement lagoon could secure some of the benefits of an active system whilst preserving those of a passive system.

An ochre slurry settlement lagoon was equipped with EKG materials comprising a basal anode mesh and a floating cathode raft. The EKG treatment was two fold:

  • Phase 1 use electrophoresis to increase the rate of settlement from suspension, then
  • Phase 2 apply electroosmosis to consolidate and dewater the material settled from suspension.

The results showed that electrokinetic technology is applicable to ochre slurries and produces solid-liquid separation at a very accelerated rate compared to passive systems. Site data indicate that electrokinetic dewatering is approximately 15% more cost effective than comparable dewatering using a centrifuge.

ICE paper published on the benefits of EKG treatment

The conventional techniques used to repair cut and embankment slope failures have many technical limitations, and most cause considerable environmental disturbance. Electrokinetic geosynthetic (EKG) treatment of failing or failed slopes offers a more effective and economical solution than traditional approaches.

This ICE published paper provides a brief description of the EKG treatment method and illustrates the engineering sustainability with two case histories. Click here to view the paper in full.

Three-time winner at the ICE West Midlands Awards

Despite a record number of entries, Electrokinetic and Amey Consulting not only won the Innovation Award, and the Geotechnical Award, but also the prestigious Overall Winner Award, scooping up three awards for their pioneering embankment remediation project on junction 7 of the M5.

Celebrating the region’s best Civil Engineering Projects, the 2013 ICE Awards were attended by more than 300 engineering professionals. In announcing the Overall Winner, the ICE judges noted; “This innovative project’s use of cutting edge technology to provide a geotechnical solution at minimal cost to the tax payer impressed the judges so much that it was successful in winning both the Innovation and the Geotechnical Awards.”

Together with an Energy and Environment Award and an Institute of Highways Engineers Award, this brings to four the number of awards that Electrokinetic has picked up this season.

The Highways Agency recognises EKG's class-leading performance

On 6 December the HA (Highways Agency) announced the winners and highly commended entrants for the second year of its Supplier Recognition Scheme. The HA scheme recognises the contribution and roles played by SMEs and new technology in maintaining the network and delivering sustainable and value-adding solutions.

Electrokinetic Ltd and Interserve Construction Ltd were highly commended in the category of Delivering sustainable value and solutions, for jointly delivering an embankment repair solution on the A21 in Kent, using the new technology of electrokinetic geosynthetics.

The project came in on time with a significant reduction in costs to the Highways Agency and a reduced carbon footprint, whilst preserving the trees and habitats for endangered species and causing minimal disruption to local residents and motorists.

The technology and equipment used in the A21 project has now been redeployed in a similar HA project on the M5.

EKG slope stabilisation wins a prestigious Green Apple

The A21 Stocks Green slope stabilisation project in Kent, which used Electrokinetic’s patented EKG technology, has won a 2012 Green Apple Award, the prestigious awards programme for sustainability and green endeavour in the built environment. The project was managed by Balfour Beatty Mott MacDonald (BBMM) for the Highways Agency.

Traditional embankment stabilisation techniques have severe environmental impacts during construction and leave behind a stark legacy of a bare embankment unsuitable for wildlife and unsightly for local residents.

The Highways Agency were particularly pleased that the project not only delivered a 40% reduction in the carbon footprint of the works, but also a significant 30% cost saving compared to conventional slope stabilisation techniques.

Electrokinetic’s novel EKG technology resulted in numerous environmental benefits which were noted by the judges, who also commented, “What was particularly impressive about the Stocks Green 1 scheme was just how transferrable the innovative technology is.

“The judges look for projects which can be developed and replicated as part of an ongoing programme of environmental best practice so we were impressed to hear the technology had already been implemented elsewhere in the country – a sure testament to its success.”

The Green Apple Awards are hailed as Europe’s longest running international environmental awards honouring excellence in sustainable construction, design and innovation of products.

ICE Innovation Award for cost-saving EKG technology

Electrokinetic’s EKG technology picked up the award for Innovation at the Institution of Civil Engineers’ (ICE) regional Excellence Awards in June.

The award was given for the pioneering slope stabilisation project at Stocks Green, commissioned by the Highways Agency. The patented EKG technology, already widely recognised for its many environmental benefits, produced zero waste and a 40% reduction in the carbon footprint of the works.

The Highways Agency has reported an indicated cost saving of approximately 30% compared to conventional treatment and has now moved the equipment to start work on a second site. Given the substantial cost-saving the HA is now assessing the application of EKG technology for other sites.
