摘要： In a wastewater treatment system, a clarifier has a submerged effluent launder, with a sloped, submerged plate that allows clarified liquid to exit through submerged openings. The sloped surface tends to accumulate solids, which can lead to algae growth. Typical internal scum collection system equipment prevents any efficient way to clear the accumulated sludge off the launder surface because of interferences. As disclosed here, a scum discharge area or box is placed external to the clarifier in one embodiment. Scum is wiped from a vertical surface of the launder assembly, above the sloped launder surface, and swept over a scum beach at one position in the clarifier, to drop into a lower trough and the flow out through the clarifier wall to a drop out box or scum discharge area. This allows for a rake-attached, sweeping launder wiper to be moved with the clarifier's rake to remove the accumulation of sludge from the launder's submerged surface, without elaborate moving parts. The sludge is swept back to settle in the clarifier, improving effluent quality by preventing sludge from exiting along with clarified water. In another embodiment the scum discharge box is internal, as a low-profile vertically disposed channel against the inside clarifier wall, leading to an existing scum pipe through the clarifier wall.

摘要： A liquid level control system employs a flap gate for discharging liquid, but with a midstream headloss inducing device between the basin or tank and the flap gate. The flap gate opens when liquid level in the basin rises, and the opening of the gate is controlled by a counterweight positioned so as to decrease closing force as the gate opens farther, thus managing the outflow of liquid to efficiently return the basin to a design level. If flow from the basin is generally constant, the system will reach a point of equilibrium of gate opening and closing forces while liquid flows out from the basin.

摘要： A liquid level control system, which may be used with a clarifier in a sewage treatment plant, manages liquid level of an upstream basin by controlling liquid flow in or out of a system that may use a midstream device to equally distribute flow in or out of the basin. This headloss inducing device creates a non-linear relationship between upstream liquid level to be controlled and the lesser downstream liquid level behind the gate or valve. Without the use of electrical controls, the systems of the invention include a gate or valve with counterforces that manage the outflow stream of liquid while accounting for the non-linear head loss created by the midstream device, thus reaching a desired liquid level range for all system flowrates.
