Aerobic granular sludge technology can be regarded as the future standard for industrial and municipal wastewater treatment. As a consequence, a growing number of institutes and universities focus their scientific research on this new technology. Recently, after extensive Dutch research and development effort, an aerobic granular biomass technology has become available to the market. Full scale installations for both industrial and municipal applications are already on stream, under construction or in design. The technology is distinguished by the name ‘Nereda®’ and based on the specific characteristics of aerobic granular sludge. It can be considered as the first mature aerobic granular sludge technology applied at full scale. It improves on traditional activated sludge systems by a significantly lower use of energy and chemicals, its compactness and its favorable capital and operational costs.

Abstract Aerobic granular sludge is seen as the future standard for industrial and municipal wastewater treatment. Through a Dutch research and development program, a full-scale aerobic granular biomass technology has been developed – the Nereda® technology – which has been implemented to treat municipal and industrial wastewater. The Nereda® system is considered to be the first aerobic granular sludge technology applied at full-scale and more than 40 municipal and industrial plants are now in operation or under construction worldwide. Further plants are in the planning and design phase, including plants with capacities exceeding 1 million PE. Data from operational plants confirm the system's advantages with regard to treatment performance, energy-efficiency and cost-effectiveness. In addition, a new possibility for extracting alginate-like exopolysaccharides (ALE) from aerobic granular sludge has emerged which could provide sustainable reuse opportunities. The case is therefore made for a shift away from the ‘activated sludge approach’ towards an ‘aerobic granular approach’, which would assist in addressing the challenges facing the wastewater treatment industry in Asia and beyond.

In the period 2003 to date, in the Netherlands an extensive research has been conducted for the development of a new breakthrough waste water technology. This Nereda® technology is based upon aerobic granular sludge and distinguishes itself from traditional activated sludge systems by a significant lower energy and chemical consumption, much less space requirements and lower costs. The STOWA, University of Delft, DHV and six Dutch water boards participate in a Dutch Nereda® development program. At five WWTPs in the Netherlands pilot research focused on granulation and nutrient removal and was supported by fundamental research. The achievements resulted in demonstration plants in South Africa and Portugal. The first full scale applications will be realized in the Netherlands. Currently world's first full scale plant at Epe, The Netherlands is under construction and will be started up in 2011. This article summarizes the results of the pilot scale investigations, executed in The Netherlands at five different municipal waste water treatment plants.

Set Up

Abstract The first full-scale Hybrid Vertical Anaerobic Aerobic Biofilm (HyVAB) reactor has been set up for treating wastewater from a vegetable processing industry in Grimstad, Norway. The novel HyVAB reactor integrates a bottom expanded granular sludge bed with a top aerobic biofilm stage, resulting in a small footprint and high treatment efficiency. The full scale holistic treatment plant consists of a pretreatment system of a sand trap and an equalization tank, a HyVAB reactor and an effluent sludge settlement tank. The HyVAB system has been operated continuously for 219 days with flow and chemical oxygen demand (COD) fluctuations corresponding to different product seasons. The reactor hydraulic retention time ranges from 32 to 10 hours, with the anaerobic organic loading rate (OLR) reaching a maximum 16 kg-COD/m3·d. The HyVAB removed on average of 90% of the total feed COD, at an operational temperature of 25 °C. Sludge production was low at 0.11 kg-volatile suspended solids/kg-COD removed. Odorless effluent from HyVAB can be discharged directly to a local municipal wastewater treatment plant without sludge handling. Over 82% of feed COD was converted to methane, leaving high methane content (84 ± 2%) biogas out of the reactor. Energy consumption of HyVAB was 0.5 kwh/ton wastewater. The cost of wastewater treatment is 1.5 NOK/kg COD removed (based on rates in Norway).
