Water and wastewater remedy knowledgeable Envirogen Group has been awarded a £1m+ contract by Fortum Glasgow to demineralise water for the boilers at its new South Clyde Power Centre (SCEC) in Glasgow. This EfW sector mission will deploy two of Envirogen’s compact Eco MultiPro models, complemented by pre-treatment and sprucing vessels, because the group explains right here.
The contract will present the ultrapure water high quality wanted to generate 45 megawatts electrical (Mwe) of decrease carbon electrical energy from residual, non-recyclable family waste; sufficient to energy the equal of round 70,000 houses yearly.
And by incinerating family waste to warmth the boilers, the plant will stop as much as 350,000 tonnes of family waste going to landfill yearly – the equal of the waste arising from some 380,000 households. It can due to this fact meet the Scottish authorities’s new landfill measure to ban biodegradable municipal waste going to landfill from December thirty first 2025 onwards.
Fortum selected the Envirogen system due to Eco MultiPro’s success in different EfW power operations, together with Very important Energi’s Drakelow EfW plant close to Burton-on-Trent, Staffordshire.
The whole bundle from Envirogen includes its Eco MultiPro based mostly demineralised water system design, provide, set up, commissioning, coaching and prolonged guarantee. Following commissioning, the plant will produce handled water high quality of three/hr flowrate, achieved by a circulate from every unit of 15m3/hr.
Eco MultiPro is a skid-mounted reverse osmosis and electrodeionisation (RO-DI) water remedy system that delivers excessive purity water, with low working prices, chemical free operation and a compact design to avoid wasting area.
Envirogen will ship the models and pretreatment resolution by summer time subsequent 12 months, set up the tools within the autumn of 2025 and fee it in January 2026.
Sustainable
Ilkka Toijala, Head of Fortum UK, feedback, “Envirogen labored with our technical crew to develop an answer that gives a plant able to supplying dependable water in a time-efficient and cost-efficient method, aligning with our sustainability targets. That was helped by Envirogen having an extended and confirmed monitor document in industrial water remedy.
“We assessed the corporate’s different Power from Waste MultiPro options and concluded that Eco MultiPro could be perfect water remedy expertise for the South Clyde Power Centre.”
Important
Demineralised water shall be important for the trouble-free operation of the boilers and generators.
Simon Radford, Head of Gross sales, Envirogen Group says, “Steam generators are extremely delicate to corrosion and scale build-up. Scale-forming ions and suspended solids from mains water can deposit on turbine blades and inside pipework, risking injury. Utilizing demineralised water is completely essential. Regardless of the steam cycle being a closed system, fashionable boilers nonetheless want a gradual provide of demineralised water to compensate for inevitable losses resulting from steam leaks, blowdown and different operational processes.”
Eco MultiPro’s three-stage remedy
Heating water is energy-intensive, and scale formation reduces effectivity. Envirogen’s reply to that’s the Eco MultiPro, with its three-stage membrane remedy course of – reverse osmosis, fuel switch membranes and steady electrodeionisation (CEDI). Collectively, these levels take away all scale-forming ions, guaranteeing optimum efficiency and low working prices.
Prime quality, no hazardous chemical compounds
Radford feedback, “We labored intently with the plant designer, AFRY, from an early stage to develop a membrane-based resolution to match the sustainability wants of the plant. The membranes will enable Envirogen’s ‘state-of-the-art’ MultiPro models to supply top quality demineralised water with out having to resort to the usage of hazardous chemical compounds on website.
”General, the strong, dependable design focuses on complete life working prices for each utility and upkeep over a 30-year design life.
Envirogen’s membranes are sturdy and long-lasting, and so ship appreciable value financial savings as a result of they want changing much less typically. Moreover, the RO-CEDI skid requires no chemical regeneration, relying as a substitute on a small quantity of electrical energy to resume the membranes. Your complete demineralisation course of carries a a lot decrease working value in comparison with a traditional resin-bed resolution, particularly as, on this case, it utilises electrical energy that’s generated on-site.
