Notes and Observations Cont.... <br />(20) <br />Flow rate was increased to 20.7 gpm. Tanks filled by 9:00 <br />AM <br />(21) <br />Pumps were stopped to secure the hose in the discharge <br />channel. <br />The City bypassed specific treatment processes during <br />(22) <br />construction. Slight drops in UV transmittance could be <br />due to the decreased performance of the system to <br />remove solids. <br />Flow rate increased to 25 gpm (36,000 gpd). The large <br />pump was set to 15 gpm (48 Hz on the VFD) and the small <br />(23) <br />pump was set to 10 gpm by throttling the valve on the <br />effluent line. The recycle valve was left at 100% open. <br />(24) <br />Flow rate was increased to 24.8 gpm. <br />The flow rate was reduced to 9.5 gpm because the landfill <br />was not able to deliver enough leachate to meet the <br />(25) <br />demand of 36,000 gpd. The leachate was very black in <br />color and turned the anaerobic tanks black. Only 3 <br />truckloads were delivered today. Possibility of no trucks <br />tomorrow. <br />The City began feeding chlorine prior to sand filtration <br />(26) <br />because the UV transmittance was dropping. The chlorine <br />took some of the color out of the water. <br />(27) <br />Flow rate was increased to 20.7 gpm. <br />(28) <br />Flow rate was reduced to 6.7 gpm for the weekend. <br />(29) <br />City stopped feeding chlorine. <br />(30) <br />Flow rate was increased to 24.8 gpm. <br />(31) <br />Flow rate was reduced to 6.7 gpm for the weekend. <br />Pilot Study was stopped. The pumps were turned off and <br />(32) <br />the tanks were cleaned out by flushing clean water <br />through. No leachate was delivered. <br />
