Jonas Scholz is interning for the City of Elk River for the summer working with various city departments including waste water, stormwater, engineering, planning and energy city. He is studying Environmental Engineering in Munster, Germany. Below is his work schedule for this first month here. Wastewater Treatment Plant May 8-June 2, 2017 POC: Matt Stevens, Chief Wastewater Operator Jonas will be involved in the following activities for the month he is at the WWTP: The Chief WW and Lead Operators will take Jonas on a plant tour; explain plant processes and daily operations. Site inspections will be conducted at the systems 21 lift stations, and he will gain an understanding of how 77 miles of sewer gets to the Elk River Wastewater Treatment Plant. Jonas will participate in plant walk-throughs to ensure all buildings are secure, and processes are functioning as designed. He will run calculations to determine how many hours each pump ran during the week. He will learn how the city GIS system is used in conjunction with the wastewater SCADA system. He will observe the removal and replacement of defective panels at two of the system's lift stations. The Chief Wastewater Operator will review process control and protocol for municipal wastewater plants, including state and federal regulations, permit rules, reporting requirements and enforceme Jonas will collect and record plant influent and effluent amounts sent to UC Labs; conduct lab tests which include DO,Transmittance and Total Chlorine. He will assist with running total solids test on the aeration basin, the return activated sludge, and the effluent of the final clarifier. He will calculate the SRT to determine the amount of water we need to waste to the storage tanks. Jonas will spend time running total solids on the storage tanks to determine the correct amount of polymer needed to obtain the highest percent solids product from the screw presses. He will also have the opportunity to run the presses to achieve maximum efficiency from both presses. He will collect samples from the aeration basin and view them under a microscope. By analyzing the types of microorganisms present, he can more accurately determine the best biological treatment to use.This will help Jonas identify whether we have young or old sludge; which determines if additional waste needs to go into the storage tanks. Jonas will experience the pipe jetting process, any main breaks, line hits, or sewer back-ups, as part of a normal day at the wastewater plant.
