De Watermaker

Due to climate change it rains more often and harder, which creates flooding in the city. This with the result that dirty water gets mixed with clean groundwater. The purification of water is therefore more difficult and expensive. The quality of drinking water will dramatically reverse and clean water is scarce.

The Ocean Cleanup

Every week the volume of two Empire State Buildings worth of plastic floats into the oceans, where it damages ecosystems, damages economies and enters the food chain, thereby potentially damaging us humans. Yearly this is about 8 million tons of plastic.

Nereda

Nereda is the innovative, sustainable and cost-effective biological wastewater treatment technology that purifies water using the unique features of aerobic granular biomass. Nereda plants require a quarter of the area of traditional installations; the process consumes much less energy; and it is entirely based on natural ingredients.

Mobile dikes

The Netherlands is the expert in the field of water. We are the best protected delta in the world, but even we have to face challenges. In combating flooding type of threats, The Netherlands is still old-fashioned as an expert, sandbags are still the first thought in preventing floods.

Optiqua

Optiqua has developed a sensor with the size of a chip that is able to detect a sudden pollution in drinking water online. The company has in recent years, along with drinking water company Vitens and PUB Singapore's water company, worked on the development of sensor technology that is originated at the University of Twente.

Urban Street Forest

The Urban Street Forest project stands for making the city’s high-rises vertically greener. The high-rise apartments often has an anonymous character and is usually found in gray focus districts. Planting small trees on the balconies of these flat-buildings can improve the quality of the environment.

AquaReUse

AquaReUse is a purification project in which the waste water of a cluster greenhouses is purified. The same companies (re)use the purified water then again as irrigation water. Herewith a closed water cycle is realized.

CADoS

The object of the CADoS project is to develop and to build a prototype of the Cellulose Assisted Dewatering of Sludge (CADoS) water treatment concept at the Ulrum sewage-treatment plant. The CADoS principle will be applied to use a new sieving technology innovatively within an existing wastewater treatment process. The innovation consists of the sustainable reuse of toilet paper in sewage treatment plants.

GETIJDENCENTRALE

Voor de kust van Texel wordt een centrale geplaatst die met behulp van zeestromingen energie kan opwekken. Deze getijdencentrale moet vanaf 2015 op het eiland voor schone energie gaan zorgen. De centrale bestaat uit modules ter grootte van drie zeecontainers. De modules drijven op het water, waardoor de gevoelige apparatuur zich boven water bevindt. Onder het wateroppervlak wekt een turbine energie op.

DELTASYNC

The predicted shortages in water, fuel and food show that the need to build floating cities is greater than ever before. The current food crisis demonstrates that agricultural production has difficulty in keeping up with a growing population and prosperity. Agricultural productivity is scarcely growing any more, because the most important raw materials – water, phosphates and fuel – are coming under increasing pressure.

SMART POLDER

Smart Polder is a solution that combines water management with the generation and efficient use of renewable energy. In the Smart Polder, the pumping away of surface water is combined with the extraction of heat and cold from that surface water. Energy is transported via a heat exchanger by means of a ‘Smart City Thermal Grid’ with which homes, offices and other buildings can be heated or cooled.

BLUERISE

Covering seventy percent of our globe, the oceans are the largest solar collector and can provide a vast amount of clean and renewable energy, day and night all year round. Ocean Thermal Energy is destined to become the leading source of renewable energy worldwide. Bluerise provides advanced technology and systems that use temperature differences in the oceans to generate electricity, cooling and fresh water.
