Royal HaskoningDHV and Anglian Water have joined forces to deliver Net Zero digestion technology
Royal HaskoningDHV and Anglian Water have entered into a cooperation agreement to bring the HpH digestion technology, developed by Anglian Water, to market in the UK and abroad. Part of the agreement includes the transfer of the existing HpH patent to Royal HaskoningDHV.
The HPH technology will go to market under the name Helea and will support water companies to meet their Net Zero targets by offering a more affordable and sustainable route to advanced sludge digestion.
Peter Simpson, CEO of Anglian Water said: “We are really proud to have developed this innovative, green technology at Anglian Water – it epitomises what we stand for as a business – forward thinking, environmentally conscious and always looking for better ways of doing things."
Every wastewater treatment plant (WWTP) produces sludge as part of the treatment process. The treatment and disposal of these biosolids is expensive, representing up to 70% of a plant’s operating costs. Responsible for processing around 150,000 tonnes of sludge per annum, Anglian Water identified an opportunity to develop a new hydrolysis technology that would maximise a plant’s biogas production from sludge. This would also reduce operating costs and the plant’s carbon footprint too. This technology is now successfully installed across four Anglian Water sludge treatment plants.
"We have benefitted from HpH technology over the past six years at four of our recycling centres and now, we are excited to work with Royal HaskoningDHV, leading international consulting engineers, to increase the access to this advanced technology across the UK and beyond", says Simpson. "The advantages of Helea combined with other treatment technologies will in our experience provide significant benefits, both in process efficiency as well as cost savings and the environment.”
Net Zero targets
Helea provides wastewater companies with a technology that significantly increases the biogas yield over conventional digestion. At the same time, it transforms the remaining biosolids into a high-quality biosolids resource that can be utilised in agriculture as a nutrient and a soil conditioner. With these characteristics, it supports the wastewater industry to achieve its Net Zero targets.
"We are excited about the opportunities for this technology in the water sector, both in the UK and abroad. With the environmental and climate changes that surround us, there is an increasing focus on resource recovery and energy efficiency," according to Erik Oostwegel, CEO Royal HaskoningDHV
