Integrated scum baffle and launder cover for use in a clarifier tank

A water treatment tank apparatus including an influent, at least one substantially vertical peripheral wall forming a launder channel having an upper and an interior surface, a substantially vertical weir connected to said vertical peripheral wall, said launder channel having a width, said water treatment tank apparatus comprising:

• a second weir, mounted on a second weir support disposed substantially in the middle of said launder channel, said second weir and said second weir support subdividing said lauder in channel into first and second sub-channels;
• a cover section, said cover section having first and second ends, said first end being secured to an outer tank wall and said second end positioned over the entire launder channel including both sub-channels and inwards to a scum baffle and integrated mounting bracket, for preventing light from reaching interior surfaces thereof, said at least one panel member being dimensioned to span the width of said launder channel including a weir and spillway of said channel, and being comprised of a substantially opaque material, whereby the growth of algae on fluid contacting surfaces of the launder channel, weir, second weir and spillway is inhibited;
• a support flange coupled to said tank wall for supporting said first end of said cover section;
• a bracket mount for attaching said scum baffle with integrated mounting bracket to said vertical peripheral wall, said scum baffle with integrated mounting bracket having a baffle portion, a cover portion and a mounting bracket portion wherein said mounting bracket portion extends away from said peripheral wall for a distance greater than the length of said cover portion of said scum baffle with integral mounting bracket;
• and
• a pivot means coupled to said cover portion of said scum baffle with integral mounting bracket and to said cover section for pivoting said cover section away from said outer tank wall about a pivot axis between a first closed position and a second open position so as to allow complete access for cleaning and inspection of said weir second weir, spillway and launder channel.
