Abstract:
A wastewater storage tank comprising:a cylindrical wall having a first closed end and a second closed end; two coalescers positioned inside the cylindrical wall, each of the coalescers having a proximal end and a distal end, the coalescers being spaced apart to define a central path between the coalescers, each of the coalescers being spaced apart from at least a portion of the wall to form a side path between each coalescer and the wall; a first baffle positioned adjacent to the proximal end of each coalescer and extending between the coalescers to close the central path; and a second baffle comprising a first baffle portion and a second baffle portion, each of the baffle portions being positioned adjacent to the distal end of a coalescer and extending from the coalescer to the wall such that the corresponding side path is blocked; wherein the tank is configured such that the first baffle and the second baffle cause wastewater to flow past one of the baffles, through the coalescers, and past the second baffle as the wastewater flows between the first closed end and the second closed end of the tank.
