Water treatment is essential around the world, whether an area is water scarce or not. Challenges vary depending on the geographical area, state of technological knowledge and water polluting reasons. Water treatment can contribute in reaching many of the Sustainable Development Goals. Removing pollutants as well as concepts for using wastewater in agricultural systems, benefits rural areas as well as cities by providing access to clean water. But it also tackles the challenge of depleting resources by using innovative concepts recovering valuable resources like ammonium from water. The session is introduced by Achim Ried (Xylem) and moderated by Ricardo Cepeda Marquez (Solid Waste Initiative).

Aerobic granular sludge of the Nereda® technology is characterized with the presence of a biopolymer termed ‘alginate-like exopolysaccharides’ (ALE). This material has many unique features and offers various potentially high-quality applications. By extracting this, water authorities are taking concrete steps towards achieving a circular economy. Market parties have shown interest in using this biopolymer.

Recovery of phosphorus and nitrogen from waste streams is of interest. Drainage and leachate of these elements to air and water bodies cause global warming and eutrophication. We discuss removal of ammonium and phosphate from wastewater by sorption on alumino-silicate. The geopolymers are prepared from industrial by-products. Exhausted adsorbents are used for fertilizing product.

Cooling systems dissipate excess low temperature heat from industrial processes. Model calculations from two case studies showed that a shift from curative conditioning of cooling water by addition of complex chemicals to preventive conditioning by complete softening can lead to a reduction of water use and chemicals, benefitting the environment.

Sieving of the wastewater at WWTP Schiphol using fine sieves produces sieved material which can be converted to a carbon source, and it increases the treatment capacity. The presentation will show results of lab tests on the conversion to a carbon source, CO2 footprint and business case for WWTP Schiphol.

RichWater is an EU funded project that aims to demonstrate a technology for wastewater reuse in agriculture. RichWater integrates wastewater treatment and irrigation in a single system in order to ensure safe and optimal use of water and nutrients by tailor-made treatment and exhaustive control and monitoring of the effluent.
