奥尔伯根污水处理厂已进行升级，通过对工业（土豆）废水和废水进行单独和专门的处理来提高出水质量。在有益的公私伙伴关系中实现了单独的工业处理。工业废水和污泥处理流出物的浓缩流的单独处理被证明比组合的传统处理工艺更具成本效益、面积和能源效益。工业废水首先在UASB反应器中进行处理以生产沼气。将UASB反应器流出物与废水合并，并在鸟粪石反应器（磷酸盐法）中处理，然后进行一级颗粒污泥亚硝化/厌氧氨氧化工艺。这两个反应堆首次在全规模上进行了演示，并在3年内稳定运行。回收的鸟粪石已被测试作为商业肥料的合适替代品。颗粒状厌氧氨氧化生物质长期暴露于亚硝酸盐水平高达30毫克/升没有导致在此反应器配置中的厌氧氨氧化细菌的抑制。选择的方案需要小17倍的反应堆体积（体积减少20，000 m3），每年节省约1.5 GWh的电力。
The Olburgen sewage treatment plant has been upgraded to improve the effluent quality by implementing a separate and dedicated treatment for industrial (potato) wastewater and reject water. The separate industrial treatment has been realized within a beneficial public-private partnership. The separate treatment of the concentrated flows of industrial wastewater and sludge treatment effluent proved to be more cost-efficient and area and energy efficient than a combined traditional treatment process. The industrial wastewater was first treated in a UASB reactor for biogas production. The UASB reactor effluent was combined with the reject water and treated in a struvite reactor (Phospaq process) followed by a one stage granular sludge nitritation/anammox process. For the first time both reactors where demonstrated on full scale and have been operated stable over a period of 3 years. The recovered struvite has been tested as a suitable substitute for commercial fertilizers. Prolonged exposure of granular anammox biomass to nitrite levels up to 30 mg/l did not result in inhibition of the anammox bacteria in this reactor configuration. The chosen option required a 17 times smaller reactorvolume (20,000 m(3) less volume) and saves electric power by approximately 1.5 GWh per year.
