Inclined plates for CSO

A liquid purification assembly comprising:

• an inclined cell separator having a plurality of rectangular plates positioned between opposing spaced-apart substantially vertical weirs, the plurality of plates being substantially parallel with one another and extending substantially perpendicular to the opposing weirs, the plates having opposing elongated top and bottom edges and front and rear surfaces therebetween, the plates having an inclined orientation relative a vertical axis, said inclined orientation forming angled cells between adjacent plates of the plurality, the weirs comprising a first weir and a second weir being substantially parallel to one another, the first and second weirs having opposing top and bottom edges and front and rear surfaces therebetween;
• the inclined cell separator being located within a chamber formed by opposing end walls, opposing side walls, a top and a bottom, the opposing end walls comprising an influent wall having an influent opening therein and an effluent wall having an effluent opening therein, the first and second weirs extending between the opposing side walls of the chamber;
• an influent chamber between the influent wall and the first vertical weir;
• an effluent chamber between the second vertical weir and the effluent wall;
• a sediment collection area along the bottom of the chamber below the inclined cell separator and between the influent chamber and effluent chamber;
• a hinged baffle suspended below the bottom edge of the second vertical weir, the hinged baffle hanging in a substantially vertical position from the second weir during periods where liquid is not flowing into the chamber at a flow rate sufficient to produce upward rotation of the baffle, the hinged baffle being rotatable upward during periods where liquid flows into the chamber at a flow rate sufficient to push the hinged baffle towards the effluent wall whereupon the hinged baffle restricts liquid from entering the effluent chamber from the sediment collection area.
