History of the Amsterdam Water cycle: a boat tour (Maarten Ouboter, Wilco Koning)
The history of the Amsterdam water cycle is fascinating. Recently, we celebrated 400 year canals, 160 year drinking water and a 100 year old sewersystem. In what way has the robust canal city developed in this marsh land? How do we manage the water levels in this territory? How did the city get their drinking water? How did we deal with our waste and our waste water? How is it possible that, nowadays, people organize swimming events in the Amsterdam canals? During a boat tour through the canals we share our (hi)stories with you.

From waste to new resources and energy: Wastewater Treatment Plant Amsterdam-West & Waste to Energy Plant Amsterdam
Climate change, growth of the world population, shortage of raw materials and fast-growing cities lead worldwide to the necessity of changing our behaviour towards water, energy and waste materials: use less, and recycle more on a high level quality. A circular approach contributes to a green economy and asks for integrated solutions. As an example of an integrated solution you can visit the largest Wastewater Treatment Plant (WTP) in Amsterdam (1 million p.e.) in combination with the largest Waste to Energy plant in the world. More than 1.5 million ton of waste and sludge is incinerated at this plant. This is an example of sophisticated, technological and industrial process integration. By recovering and re-using waste, heat and by-products they provide in raw materials for production processes. For delivering the sludge and biogas the WTP receives in return 100,000 MWh/year and heat. This prevents the use of 1 mln m3 natural gas and the emission of 1,800 ton CO2-eq per year. The integration results also in the production of circa 25,000 MWh electricity and 75,000 GJ heat that is distributed for district heating to households. This means a reduction of 285 TJ energy and 15,000 ton CO2.

State of the art Wastewater Treatment: Wastewater Treatment Pland Epe with Nereda
Nereda® is an innovative and advanced biological wastewater treatment technology that purifies water using the unique features of ‘aerobic granular biomass’. Contrary to conventional processes, the purifying bacteria concentrate naturally in compact granules, with superb settling properties. As a result of the large variety of biological processes that simultaneously take place in the granular biomass, Nereda® is capable of producing excellent effluent quality. Even when not particularly targeted, extensive biological phosphorus and nitrogen reduction is an intrinsic attribute of this technology, resulting generally in chemical-free operation. These unique process features translate into compact, energy saving and easy to operate Nereda® installations for both industrial and municipal wastewater treatment. Nereda® presents attractive new solutions for green field installations and retrofitting or extending conventional activated sludge plants. The technology is also highly recommended for performance and capacity upgrades of existing SBR-facilities. We will visit the world’s first full-scale municipal sewage treatment plant using the cutting-edge Nereda technology in the Dutch town of Epe.

State of the art Drinking Water Treatment: Andijk III: world’s first water treatment plant combining suspended ion exchange and ceramic membranes
The Andijk III plant in the Netherlands is based on PWN Technologies’ SIX® (Suspended Ion eXchange) and CeraMac® (ceramic membrane filtration process). It produces water of a better quality with lower environmental impact and less energy consumption. Andijk III has a capacity of 5,000 m3 per hour or 120,000 m3 a day.

SIX® removes dissolved organic substances, nitrate and sulphate. SIX® also ensures that the ceramic membranes are not contaminated too quickly. The passage through the ceramic membranes is the next phase of the treatment process. All particles larger than 1/10,000th of a millimeter are removed. Ceramic membranes have a very long lifetime and high durability. Also their permeability and high backwash rates allow for much higher gross fluxes (3 to 4 times) at a stable operation leading to less membrane area and therefore a smaller footprint. CeraMac® combines up to 192 ceramic membrane elements into one vessel, making it a highly economical and compact solution.

In combination with existing UV-peroxide technology and active carbon filtration SIX® and CeraMac® lead to a very robust and sustainable water treatment.
Andijk III is the result of years of experience with water treatment, extensive research and exhaustive testing, both in the Netherlands and abroad. In 2012 the International Water Association (IWA) awarded the project the Innovation Award.

Cindy Wallis-Lage, President Global Water Business at Black & Veatch, qualifies Andijk III as an excellent example of ‘disruptive innovation’: “This is what makes a difference. It takes a journey to make innovation move faster: integration and sharing of knowledge as well as collaboration. Together we can achieve so much.”

“Water is complex, but the goal is simple”, says IWA President Glen Daigger, “We can provide people with reliable water. Therefore we must change what we do, like PWN Technologies has done here. Andijk III is a major example.”

Dr. Shane Snyder, Professor chemical and environmental engineering at the University of Arizona: “More companies should consider using this type of technology and scale up, to demonstrate to the world that these technologies are efficient, robust and reliable.”

Flood protection in Amsterdam & Rotterdam, a multi layer safety approach
The flood threat in the Netherlands is related to various possible flood events originating from The North Sea, from the River Rhine delta, from the inland lake IJsselmeer and from the regional water system. In Amsterdam and Rotterdam pilot project concepts are worked out to maintain and improve the safety against flooding in the region on the long term following a multi layer safety approach. In this approach the focus is not only on prevention (levees), but also on diminishing effects by spatial measures, damage control and evacuation. During the tour several flood prone areas in the cities will be visited. Guides will explain the different flood protection systems – with a specific focus on the protection of critical infrastructure – and possible multi layer safety measures related to new developments and the historical perspective. This excursion will also show how modern and future ‘smart’ (ict enhanced) flood protection structures can keep Amsterdam and Rotterdam safe in an effective, budget friendly and efficient way, with minimal claims on scarce building space.

Artificial Groundwater Recharge: the Amsterdam Dune Water Machine
Artificial recharge has been in operation in the dune area to the west of Amsterdam since 1957. The system has been in place for over 55 years and has been constantly improved and fine-tuned. The philosophy behind the Amsterdam dune recharge system is based on (1) using groundwater only for storage, removal of pathogens, and for attenuating peaks in water quality; (2) integrating the recharge system with nature restoration goals, and (3) preventing pollution of the water source in the upper catchment area. The objectives were: stop overexploitation of the freshwater resources in the dune area, restore ecological conditions, and enhance the recharge capacity to 65 million m3 per year in order to secure the water supply for the metropolitan region. This excursion will show you that this approach is still state of the art and can be – part of – the solution of securing sufficient drinking water of good quality for the many fast growing metropolitan areas worldwide.
