In June of 2005, SSI celebrated its 10th anniversary. SSI is a privately held company headquartered in Poughkeepsie, New York, USA with operations in the US, the Netherlands, Korea, China and India.

We service our customers through a network of agents and distributors in over 70 countries. We distinguish ourselves in a number of ways, but first and fore most through R & D.

SSI has filed for and been granted patents relating to the layering of thin films of VITON™ and PTFE over EPDM, for the first Bayonet type saddle mount for disc diffusers allowing interchangeability of disc diffusers of various sizes on the same piping grid, and to the development of advanced computer software which automates the drafting, spec writing, pricing and calculation functions of diffused aeration system design.

We maintain an engineering and 2-D and 3-D capable drafting department and we offer complete design assistance to consultants and customers, including use of our advanced biological simulator which can, for example, effectively predict effluent quality and model the appropriate aerobic and anoxic hydraulic retention times in nutrient removal systems.
