<p>An apparatus for use in a conventional wastewater treatment plant of the ty pe including a clarifier with a launder for use upstream of an anaerobic treatment facility includes a dam assembly defined by a dam wall and a sluice ramp for mounting in the launder downstream of a control dam for minimizing turbidity and consequentl y oxygen uptake in the wastewater discharged from the launder. The apparatus reduces noise, emission of noxious and malodorous gases, loss of volatile fatty acids from the wastewater, uptake of oxygen into the wastewater and algae growth of in the clarifier.</p> |
