A water treatment team has reduced maintenance downtime and increased revenue at an energy-from-waste plant near Slough.
The Lakeside facility at Colnbrook incinerates 410,000 tonnes of household and municipal waste a year and exports 34 MW of electricity to the National Grid and uses waste-fired boilers generating 45bar steam to drive a turbine.
When a boiler is drained for its routine maintenance it has to be refilled with demineralised water. With limited flow from the make-up water demineralisation plant this would take around three days. And that’s where the Aquamove MOFI 35m3/h mobile plant from ELGA Process Water came in.
Martin Rogers, EHS manager at Lakeside, explained: “Hiring in the MOFI mobile unit means that we can get the boiler up and running in less than a day, and the increased generation revenue more than covers the hire cost. An Aquamove engineer can be deployed, together with the necessary equipment, fittings and documentation within two hours of a call, and that’s reassuring. It means that if we think we might have a problem with our demineralisation plant, we can always have a MOFI on standby at short notice.”
The MOFI is self contained and regeneration is carried out at ELGA’s regeneration station in Stoke-on-Trent so there is no chemical or waste handling on site.
