Inclined plates for CSO

A water purifying chamber comprising:

• a first chamber enclosure with a bottom, a top, substantially vertical opposing first and second end walls and substantially vertical opposing first and second sidewalls;
• a water inlet in the first end wall permitting water to flow into the first chamber from a water source;
• a water exit in the second end wall permitting water to flow out of the first chamber, the water exit being no higher than the water inlet;
• a second chamber within a bottom portion of the first chamber where the entire second chamber is accessible from the water inlet across to the water exit;
• an inclined cell separator located between the water inlet and the water exit wherein a top of the cell separator is level with inverts of the water inlet and the water exit and wherein a bottom of the cell separator is adjacent the second chamber to deposit a settled sediment in the water flow on the bottom of the first chamber, the cell separator having a plurality of inclined lamellae plates having first and second ends and top and bottom edges, the top and bottom edges longitudinally extending parallel to the sidewalls and perpendicular to the end walls, the first and second ends of the plurality of lamellae plates being secured to opposing, spaced-apart, substantially vertical weirs, the plurality of lamellae plates being pitched at a fixed angle relative to the substantially vertical sidewalls;
• a debris collection net within the first chamber extending over at least a portion of the top of the inclined cell separator whereby water can freely flow through the net and over and down through at least a portion of the inclined cell separator;
• the spaced-apart substantially vertical weirs comprising a primary weir and a secondary weir parallel to the end walls and perpendicular to the plurality of lamellae plates, the primary weir having a top edge above the top surface of the inclined cell separator but below a top edge of the secondary weir, the primary and secondary weirs being elevated from the bottom of the primary chamber;
• an influent chamber between the first wall and the primary weir;
• an effluent chamber between the secondary weir and the second wall;
• and
• a hinged baffle below the secondary weir to control water flow below the inclined cell separator and the water flow through the ribbed inclined cell separator.
