Water and wastewater remedy skilled Envirogen Group has been awarded a £1m+ contract by Fortum Glasgow to demineralise water for the boilers at its new South Clyde Vitality Centre (SCEC) in Glasgow. This EfW sector mission will deploy two of Envirogen’s compact Eco MultiPro models, complemented by pre-treatment and sharpening 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 properties yearly.
And by incinerating family waste to warmth the boilers, the plant will forestall 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 should 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 vitality operations, together with Very important Energi’s Drakelow EfW plant close to Burton-on-Trent, Staffordshire.
The entire package deal from Envirogen includes its Eco MultiPro primarily based 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 circulation 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 house.
Envirogen will ship the models and pretreatment answer by summer time subsequent yr, set up the gear within the autumn of 2025 and fee it in January 2026.
Sustainable
Ilkka Toijala, Head of Fortum UK, feedback, “Envirogen labored with our technical group 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 report in industrial water remedy.
“We assessed the company’s other Energy from Waste MultiPro solutions and concluded that Eco MultiPro would be ideal water treatment technology for the South Clyde Energy Centre.”
Important
Demineralised water will likely be important for the trouble-free operation of the boilers and generators.
Simon Radford, Head of Gross sales, Envirogen Group says, “Steam turbines are highly sensitive to corrosion and scale build-up. Scale-forming ions and suspended solids from mains water can deposit on turbine blades and within pipework, risking damage. Using demineralised water is absolutely crucial. Despite the steam cycle being a closed system, modern boilers still need a steady supply of demineralised water to compensate for inevitable losses due to steam leaks, blowdown and other 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, gasoline switch membranes and steady electrodeionisation (CEDI). Collectively, these phases take away all scale-forming ions, making certain 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 answer to match the sustainability wants of the plant. The membranes will enable Envirogen’s ‘state of the art’ MultiPro models to provide top quality demineralised water with out having to resort to the usage of hazardous chemical compounds on web site.
”Total, the strong, dependable design focuses on entire 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 answer, particularly as, on this case, it utilises electrical energy that’s generated on-site.
