I met with Randy Joseph (ORC) at the facility. The bar screen rakings need to be better contained. Settleable solids in the aeration tank were at 89%. This is too high and some solids should be removed from the basin. The effluent weir plate is rusting and may need refurbishment. The weir box had a lot of algae/plant growth in it and definitely needed cleaning. Two of the sludge transfer lines were spouting water and mixed liquor up in the air. Randy said they were missing flaps that would keep the liquid directed in the tank. Those should be replaced. Two of the diffusers in the aeration basin appeared to not be working, as those areas showed no sign of aeration. The center well of the clarifier was clogged with solids. Randy said that the center well would get cleaned out by the pump truck. *2/8/2016* Randy says that 3600 gallons of solids have been pumped out of the aeration basins and the settleable solids level is down to 70%.
