Turnkey solution for wastewater treatment at small sites
Stringent new demands for the removal of phosphorus during waste water treatment is creating a challenge for water companies in the United Kingdom. In response, we have developed a range of small plants based on our award-winning Nereda® wastewater treatment technology. The new Nereda® Package Plants provide high-quality sustainable wastewater treatment with biological phosphorus removal at small works serving between 300 and 10,000 people. For added efficiency, the plants have been designed to be manufactured, assembled and pre-tested off-site, which allows for a highly cost-effective implementation, ensuring improved health and safety and an efficient site assembly.

The concept of wastewater as a resource is an important focus for circularity in the water sector. With the delivery of the first consignment of Kaumera Nereda® Gum in 2020, this is becoming a reality. Kaumera is a new bio-based resource extracted from aerobic granular sludge originating from the Nereda® waste water treatment process. The sustainable biopolymer provides a viable alternative to a variety of oil-based materials and can be used in sectors including agriculture, building, textiles and paper. Two large-scale Kaumera production units are now in operation.

Hong Kong selects Nereda® technology for iconic effluent polishing plant
Royal HaskoningDHV has been awarded a 100,000 m³/day wastewater treatment project in Hong Kong. The Yuen Long Effluent Polishing Plant (YLEPP) will use award-winning Nereda® aerobic granular sludge technology to biologically treat wastewater. It will be the first Nereda wastewater treatment plant on this scale in Asia.
The project will see the redevelopment of the existing Yuen Long Sewage Treatment Plant into a 100,000 m3/day Effluent Polishing Plant, with a further 80,000 m³/day expansion planned for the future. This iconic project will adopt advanced wastewater treatment technologies, feature renewable energy, incorporate extensive greening features and provides public co-use facilities for the benefit of the local community.
The availability of land is at a huge premium on Hong Kong. A small site footprint and high-efficiency are essential components of any wastewater project on the densely-populated 1,104 square kilometre island. Nereda technology was identified and assessed as one of the most promising technologies to deploy. Pilot results validated that Nereda technology could efficiently treat the particular Hong Kong wastewater characteristics, which originate from its unique seawater toilet flushing. It also validated that Nereda technology was suitable to meet the more advanced treatment requirements that are applicable for effluent polishing plants.
