Ecologia mobilised a fully automated, self contained small scale MPE system, that we designed and manufactured in the UK, to undertake the pilot trial over a period of 1 week.

The project was highly successful with the MPE unit demonstrating that removal of large volumes of DNAPL and highly contaminated groundwater is possible with this technique. The downstream treatment and separation process was carefully designed to eliminate emulsification so that phase separation is optimised and liquid waste disposal minimised with substantial saving in water treatment costs.

The pilot trial resulted in the assessment of a number of site specific parameters such as Radius of Influence (ROI), rate of extraction, Volatile Organic Compounds (VOCs) concentrations in the water and off gas which have been used to design the full scale system.

The pilot trial was carried out for a fixed price and we have approximately 12 MPE units for small in-situ projects or for pilot testing for larger projects.

Following the successful operation of the 1^st phase of works  in 2011 Ecologia was appointed to design, manufacture and install an additional system to treat  the off site plume which had impacted both soils and groundwater .

The system installed in 2009 uses Multi-Phase Extraction (MPE).  This technique applies a high vacuum for removing liquids and vapour from the subsurface utilising the same extraction well and it is particularly suited for removing liquids from shallow wells with variable water recharge dominated by precipitation.

The second system  installed in 2011 uses a  Dual Phase Extraction  (DPE)  where  down hole pumps and  high capacity vacuum blowers are combined in order to achieve independent water and vapour removal systems in anticipation that one phase may require longer remediation than the other. A system  remote  air water separators had to be installed in order to prevent  condensate built up in the SVE extraction pipework, with the liquid phase being returned to the treatment system separately to the gaseous phase.

The equipment was fully designed and built at our workshops in Kent including the design and manufacture of the control panel and telemetry system as well as the design and manufacture of the automated total volatile organic compound (TVOC) detection device.

The equipment is fully ATEX compliant and designed to be easy to use by site staff following training. Anti frost protection and cooling equipment was also incorporated in the design as the area is subject to annual temperature variation of 40⁰C to -10⁰C.

The MPE system installed in 2009 is extracting from 12 wells; whilst DPE system installed in 2011 is extracting from 10 pumps and a total of 16 SVE wells.

To date the combined system has recovered more that 30 tonnes of VOCs since the commencement of operation in 2009.

The design, manufacture and installation of both systems was undertaken within a lump sum contract and was completed on time and within budget.

The both systems are currently managed and operated by Ecologia.

We are now pleased to announce that we have purchased new offices and workshop/storage premises, very close our previous office.  Company Director, Mike Lenn, who is based at the new office, said “I am delighted that we have been able to secure this ideal business premises at this location.  The Honiton location is strategically important to us, giving excellent access throughout the South West region and also good rail and road links to London and to our head office in Kent.  The new building will allow us to maintain more supplies and equipment close to hand, allowing greater operational flexibility and improved response times”.

A rapid response and site attendance was fielded by Ecologia staff within 24 minutes of receiving the initial call.  Liaison was maintained with the client, site representatives and NIEA with protective measures put in place to mitigate the risk to the storm drain network.  As a large area of concrete pad was impacted, loose absorbents were applied over the surface area to retain free phase product prior to degreasing the entire concrete and tarmac hardstanding areas.

Through the combined use of absorbents and a vacuum tanker, all remedial works were completed with minimal disruption to the busy distribution depot and operations were able to continue during the emergency response works.
