Waterschapsbedrijf Limburg has reinvented the treatment of wastewater with the modular Verdygo design and construction technology and Royal HaskoningDHV’s Nereda technology is part of it. The 'world premiere' of Verdygo took place on 19 December, when the first Verdygo plant in Simpelveld was officially put into use.
The modular Verdygo concept offers a design and build approach with adaptable technology and leading to low operational costs. The construction allows a sewage treatment plant to adjust (expand or shrink) quickly and easily. As Ger Driessen, Chairman of Waterschapsbedrijf Limburg, points out, "This creates an enormous capacity for innovation, as we can respond flexibly to climate change, the latest advances in treatment technology and changing market demand." It also helps the reuse of effluent on the local level, for example in industry or greenhouses thus making a considerable contribution to sustainable water treatment.
Verdygo plants are conducted with, among others, Nereda technology, which adds another innovation to its concept. The Nereda technology is an aerobic wastewater treatment technology that purifies the water with the unique features of aerobic granular biomass.
