Dunphy have extensive experience in manufacturing, installing and maintaining ultra low NOx burners for sludge and wastewater treatment processes. Our burner designs mitigate the formation of thermal NOx through staged combustion supported by CFD optimised combustion heads and advanced touchscreen digital boiler/burner controls. When used with a correctly dimensioned boiler, NOx emissions are inherently low at 35mg. per kWh on gas and biogas. Burner components are designed and manufactured in materials which resist corrosion thus reducing expensive maintenance downtime. Design options also include sluice burners, retractable heads and web based software for the remote management of burners and boilers. Our factory laboratories have facilities to test the critical fuel characteristics of recovered sewerage biogases – including key calorific variations. This data then informs the engineering design of burners and boiler shells to optimise specific site combustion efficiency. Dunphy also specialise in the off-site manufacture of modular boiler houses for wastewater treatment sites. Our assembly hall adjacent to our main factory complex allows the construction of double tier containerised plant rooms which are delivered to site fully equipped and tested. The plant is ATEX compliant and we prepare all FDS reports, DSEAR analyses, SIL and risk assessments. Examples of our prefabricated energy centres can be seen on Thames Water, Severn Trent and Scottish Water sites – as well as municipal waste to energy locations. Dunphy customers benefit from direct contact with our engineers through the processes of project design, equipment manufacture and testing, installation and commissioning thus by-passing the alternative, lengthy third party contractual chain. Our customers include: Dŵr Cymru Welsh Water Uisce Éireann Northumbrian Water Severn Trent Scottish Water Southern Water Thames Water United Utilities Wessex Water Yorkshire Water

Elmo Rietschle, part of the Gardner Denver Group is a major manufacturer and supplier of compressed air and gas, vacuum pump, blower and fluid transfer technologies to the water and wastewater industries. Its experienced engineers can assist on the concept design of pumps for the OEM market, right through to system design for end users and custom built packages for central air or vacuum supply. Additionally, a comprehensive network of workshop and service engineers operates from five key geographical locations, offering 24-hour support and service. The company has recently added the GBH-8 to its range of side channel blowers designed for use in wastewater purification applications and in the oxygenation of activated sludge tanks. Compared to a standard blower of similar output, the new GBH-8 is 65% lighter, has a 40% smaller footprint, and offers twice the power. Using techniques such as CFD (computational fluid dynamics), the GBH-8 also offers high performance, with a continuous build-up of pressure. The unit features rotational speed control for easy setting of the optimal operating point, with pulsation free air supply and low noise levels. In addition, bearing lifetime in the GBH-8 is 20,000 hours, meaning downtime for maintenance, and the associated costs, are kept to a minimum.
