Rising polymer prices and stricter regulations exacerbate these challenges. Enter SLG-F, a sludge treatment method by Or\u00e8ge UK Ltd that significantly reduces sludge volumes for disposal. SLG-F also cuts polymer use. For Yorkshire Water, which transports sludge to drying facilities from around 700 wastewater treatment works, successfully implementing this technology would be a game changer.<\/p>\n<p style=\"font-weight: 400;\"><a href=\"https:\/\/www.orege.com\/en\/\" target=\"_blank\" rel=\"noopener\">Or\u00e8ge UK Ltd<\/a> e <a href=\"https:\/\/www.yorkshirewater.com\" target=\"_blank\" rel=\"noopener\">Yorkshire Water<\/a> entered the Climate Change Trial Reservoir in 2022 to conduct a SLG-F wastewater efficiency trial. The objective was to assess the performance and impact of SLG-F technology at one Yorkshire Water site using a skid-mounted thickening unit. The trial goals included evaluating the technology\u2019s efficiency and operational feasibility under specific performance criteria. An additional aim was to explore how SLG-F could be used more broadly within Yorkshire Water.<\/p>\n<p style=\"font-weight: 400;\">The SLG-F plug and play package plant proved itself in handling rags and grit, while consuming &#8211; at design throughput 20 m\u00b3\/hr &#8211; 7.5 kWh, which included all ancillaries. Its liquid poly dose of 2.5 to 4.5 kg\/TDS depending on solids load showcased efficiency. Operating automatically for &gt;95% of the trial period, it demonstrated reliability and efficacy. Thickened sludge up to 9% was possible, however for operational reasons 6% was deemed practical (from a variable input of 0.8 &#8211; 1.2%).<\/p>\n<h5><strong>Benef\u00edcios da abordagem\/inova\u00e7\u00e3o<\/strong><\/h5>\n<ul>\n<li><strong>Enhanced Sludge Management<\/strong>: By transforming sludge into a more manageable form with a higher dry solids content, the technology minimizes the volume of waste. Yorkshire Water imports sludge from ~700 water treatment sites: implementing SLG-F will lead to a 50% reduction in sludge tanker trips.<\/li>\n<li><strong>Reduced Carbon Footprint<\/strong>: Fewer sludge tanker trips means a smaller transportation carbon footprint. The initial wave of units will reduce annual CO\u2082 emissions from transportation by 120,000kg CO\u2082.<\/li>\n<li><strong>Lower Operating Expenses<\/strong>: The carbon savings is equivalent to a six-figure operational saving for the company over the lifespan of the asset.<\/li>\n<li><strong>Operational Efficiency<\/strong>: The ability of the SLG-F unit to operate automatically for more than 95% of the trial period with minimal human intervention translates to reduced energy use, further enhancing overall energy savings.<\/li>\n<li><strong>Reduced Disposal Costs<\/strong>: The frequency and associated costs of disposal are significantly reduced. This makes the disposal process more efficient, more sustainable and more cost effective.<\/li>\n<li><strong>Operational Flexibility<\/strong>: The plug and play nature of the SLG-F package plant allows for easy integration into existing wastewater treatment frameworks, providing a solution that can be tailored to varying operational demands and disposal requirements.<\/li>\n<\/ul>\n<h5><strong>Servi\u00e7os especializados envolvidos:<\/strong><\/h5>\n<ul>\n<li><strong>Trial Design Support: <\/strong>We evaluate technology trial plans based on users\u2019 innovation frames.
