Introduction

The patented zero-waste Crystalactor™ water treatment technology is used as advanced treatment of both drinking water and (industrial) waste water for removal of a large number of heavy metals and other inorganic compounds. The Crystalactor technology is a flexible technology that can be used for treatment of both large and small water flows.

Crystalactor is sustainable and cost-effective: compared to other technologies like precipitation, ion exchange or membrane filtration, it produces a valuable resource as revenue instead of waste and associated costs. Recently, we enhanced the Crystalactor with a smart controller, which was developed in close collaboration with Delft University of Technology and Amsterdam Water Works (Waternet). The advanced controller reduces the chemical, operational and maintenance costs by predictive control of formed pellets.

History

Royal HaskoningDHVs’ involvement with crystallization started early in the 1980’s when then we assisted Amsterdam water supply company Waternet in designing the pellet softening plants Leiduin (8,500 m3/hr) and Weesperkarspel (3,300 m3/hr) and took over the patent of the pellet softening process. We still exploit our expertise to date for numerous clients worldwide, as they rely that we mitigate the risks for achieving well-functioning and optimal state-of-the-art operational plants. We prove this as we issue process guarantees for pellet reactors if clients request us to do so. We assisted i.e. Taiwan, as a country, who adopted softening with pellet reactors nation-wide and guided them into this new venture. The technology has the widest range of application in the industry. Crystallization is proving technology for us, because we realized world's largest softening installations, recovered fluoride from sub-flows in the semi-conductor or solar panel industry, recovered phosphate as struvite/calcium phosphate, treated concentrate streams in desalination plants, harvesting heavy metals out of waste-water stream. Many other applications are available on your request.

Today

Nowadays, we still investigating in new developments like salt precipitation for brine minimization and CO2 capturing. We are happy to support you on your specific water challenge and/or new developments, on small and large scale as well. Royal HaskoningDHV will bring you unprecedented crystallization top expertise, validated by more than 30 years of experience in design, construction, testing, commissioning and operating of more than 70 plants across the globe. So, bring-in-the-Dutch'crystallization top-expertise for your own water challenge.
