Breaking Ground: Ashley Hall’s Innovative Greywater Research at RecoLab

Ashley Hall, a PhD student at Lund University, is making strides in wastewater treatment research at RecoLab in Helsingborg, Sweden. Commissioned by Sweden Water Research and NSVA (a municipal water and wastewater company), her focus is on reducing nutrient concentrations in wastewater.

The research centers on utilizing source-separated greywater for local purification. Her pilot facility at RecoLab, in Helsingborg’s Oceanhamnen area, utilizes a biological process (MBBR) combined with horizontal filters for decentralized treatment. This approach offers cost-effective solutions for new urban developments without straining existing treatment plants.

RecoLab’s testbed provides Ashley Hall with access to source-separated greywater from laundry, showers, and sinks. By purifying greywater on-site, this decentralized model not only meets regulatory standards but also reduces operational costs.

Her work exemplifies the potential of decentralized greywater treatment, contributing to sustainable urban development. The research at RecoLab is a promising step towards innovative wastewater solutions.
