Research on HydroSpin to promote the protection of waters from hygiene article pollution
Steinhardt GmbH, Taunusstein, has held European licensing rights from a Japanese consortium for the marketing and construction of the HydroSpin equipment since June 2010. HydroSpin operates with no external energy to prevent floatables and suspended solids from escaping out of the sewerage system at CSO overflows; the receiving waters are thus protected. The innovative design of the flow chamber is the key to success; a vortex is created which keeps hygiene articles, etc. within the canal system, for example, when the emergency overflow is activated by an extreme storm event. HydroSpin makes expensive screening machinery redundant, inefficient scum boards can be replaced at low cost. The technology was developed in Japan, is under patent protection worldwide and already operating in around 1,600 installations in Japan. Steinhardt GmbH, too, has already successfully brought a number of HydroSpin installations into operation in Europe.
In order to increase the acceptance of the HydroSpin system in Europe and to confirm its manifold cost-effectiveness potential, members of the Japanese consortium and Steinhardt GmbH have signed a binding agreement to commission further research work on HydroSpin with a university, as yet to be named. Further design developments can also be expected with drawings of the receiving structure and other documentation attesting to the affectivity of HydroSpin.
Representatives of the Bureau of Sewerage of Tokyo Metropolitan Government (TMG), Tokyo Metropolitan Sewerage Service Corporation (TGS), Nippon Koei Co. Ltd. and Steinhardt GmbH came together on 7th May 2014 at the booth of the Hessen Trade & Invest at the IFAT in Munich for the signature ceremony of a Letter of Intent.

This marks a new chapter in the quality of co-operation between Steinhardt GmbH and “Team Japan”. Steinhardt is now not just a manufacturing and marketing partner – for which Steinhardt is ideally qualified owing to long-standing excellent relations to local authorities and planning offices – but is now also a contributor to the establishment of scientific fundamentals and the further development of this innovative floatables removal system.
All parties are convinced that the results of the scientific investigation will deliver a better understanding of the hydrodynamic processes in the vortex chamber and the flow-optimised correlations and, additionally, will yield methods of increasing the efficiency of HydroSpin, already rated at over 70%. New applications are also expected to be identified.
Of particular importance to all parties is HydroSpin’s independence of an external energy source. HydroSpin utilises the available energy of the water flow, is virtually maintenance-free and has no moving parts. This makes the HydroSpin system an ideal practical solution for installation in places difficult to access or in technically under-developed regions.
