Abstract
A storm water separator system having side walls constructed from sheet piling to enable installation within a small footprint and in poor soil conditions. The separator system has an upper bypass chamber and a lower treatment chamber with a diffuser directing inflowing water down into the lower chamber. A flow control orifice between the two chambers near an outlet orifice in the side wall controls the quantity of flow through the lower chamber. Excess flow bypasses treatment and passes through the upper chamber.
Claims17
A separator system, comprising:
- a tank having a bottom and at least one sidewall, said at least one sidewall including sheet piling, said tank including a mid-deck defining an upper chamber and a lower chamber within said tank, said sidewall having (i) an inlet pipe extending therethrough into said chamber and defining an inlet orifice, and (ii) an outlet orifice, wherein both orifices are within said upper chamber and proximate said mid-deck;
- and
- a diffuser providing fluid communication between said upper chamber and said lower chamber through said mid-deck and for diffusing fluid flow descending through the diffuser into said lower chamber, said diffuser having walls and vanes extending above said mid-deck including a front wall adjacent said inlet orifice having a cutout portion sized and shaped such that said front wall conformingly contacts with said inlet pipe;
- wherein said mid-deck defines a flow control orifice disposed proximate said outlet orifice, said flow control orifice providing fluid communication between said upper chamber and said lower chamber.
