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.

Nereda® technology from Royal HaskoningDHV offers sustainable wastewater treatment solutions for municipal and industrial water. The natural sewage treatment process purifies water with minimal or no chemical usage by using the patented aerobic granular sludge technology. Compared to activated sludge technologies, the biological treatment power of the technology is much larger, while saving up to 50% on energy costs, delivering high quality effluent for low costs and requiring only a quarter of the area of conventional activated sludge installations. Biomass in the process develops as fast settling aerobic granular sludge. These granules have excellent settling properties, so the process does not require a separate time-consuming decant phase like conventional SBR’s. All the biological treatment processes take place simultaneously in the granules, requiring only one tank. The technology is very versatile; it can be developed as a new build or used to retrofit existing conventional CAS or SBR plants. The benefits of the technology include: Excellent treatment results and settling properties: Compared to activated sludge technologies, the biological treatment power of the technology is much larger as a considerably higher concentration of biological active mass is applied that in addition has a much higher content of microorganism that are crucial for biological nitrogen and phosphate removal. Sustainable: Compared to conventional wastewater treatment processes, the technology not only has significantly lower energy consumption and associated greenhouse gas emission, but also produces, commonly without the use of waste generating chemicals, a remarkably high effluent quality. Cost effective: The technology results in construction costs that are lower than for conventional technology as for example, tank volumes are up to four times smaller and less equipment is required. Small physical footprint: Its footprint at sewage treatment plants is reduced due to the full nutrient removal process taking place in one single reactor. Easy to operate: It has proved in operation to satisfy the most stringent purification requirements. Thanks to the nature of the technology, plant operation is easy and process performance robust. The technology is proven and applicable for even the largest applications. Currently, there are over 70 wastewater treatment plants in operation or under construction all over the world
