MBR #2 was drained completely on 10/31/2022 to look for possible plumbing issues causing extreme thickness, nothing obvious. Basin was brought back online on 11/1/2022 with effluent being diverted until 14:40, spike happened at 19:20 that evening right as MBR #2 started pumping. On 11/03/2022 effluent turbidity exceeded .5 at 12:56 basins 1 and 2 were running, NTU had already dropped by the time I got there in the field, no bubbles in the line and good flow through the meter. On 11/03/2022 we switched suction pressure transmitters to see if that had any effect on the basins thickness, it did not. That same day we put permeate pump #5 on in place of permeate pump #2 in case the flow meter for Pump #2 was off and we were pulling to much clear water out of the basin. Contacted Telstar to have flow meters calibrated. On 11/07/2022 we switched Anox basins to get more direct flow through MBR #2. |

Surface Water |
The discharge violated the receiving water limitations contained in the WDRs and NOAfor receiving water temperature. The Discharger indicated the exceedance in the temperature difference between RSW-001 and RSW-002 was due to very low flow in Magnolia Creek and unseasonably low temperatures at the time of weekly sampling. |

Order Conditions |
Turbidity Daily Maximum limit is 0.5 NTU and reported value was 00.648 NTU at EFF-001. |
Several attempts were made to solve the turbidity spikes, we were able to narrow the spikes down to MBR #2 coming online. On 10/5/2022 the UV channel was drained and flushed. On 10/7/2022 MBR #2 was taken offline and the permeate header was pressure tested the INF was also flushed to insure flow. On 10/11/2022 the effluent gate of MBR #2 was flushed because the basin was staying thick and we wanted to verify good flow through the basin. On 10/12/2022 MBR #2 was drained to observe the INF and EFF gates to make sure there were no obstructions. On 10/31/2022 MBR #2 was completely drained to observe membranes and lines to check and make sure there were no broken or loose connections. Everything appeared to be connected properly. |

We have continue to have issues with turbidity coming from the membranes. All membranes have been replaced but turbidity spike seem to be still coming from MBR #2. We plan to get the manufacture onsite to do some testing. |
On 9/15/22 the plumbing to the effluent NTU analyzer was disassembled and flushed along with the pump and tubing leading to the analyzer. On 9/19/22 the pump feeding the effluent analyzer was determined to be pumping infrequently and was replaced. On 9/30/22 the internal wiper for the effluent NTU analyzer was replaced. |

There will be department wide training, specifically dealing with proper procedure when switching, or putting permeate pumps online including a written SOP that operators can access at will. The turbidity issues that pertain to the MBR were pin-pointed to a particular cassette, and was isolated. This stopped the high NTUs, and this particular MBR basin is currently offline and is scheduled to have all membranes replaced in early July. |

Turbidity Other limit is 0.2 NTU and reported value was 0.33 NTU at FIL-001. |
The turbidity spikes were found to be caused from a bad membrane, it was noticed that when this basin was online, turbidity would spike. We have since isolated the bad membrane and have eliminated the spikes in turbidity. There are replacement membranes onsite and are tentatively scheduled for replacement. |

DMON |
Effluent turbidity exceeded 0.50 NTU for approximately 2 min. See attached Turbidity excursion sheet for exact times. |
It was determined the cause of the spike was due to a permeate pump that was previously offline for an extended amount of time returning back to service. In the future, it will be procedure to divert effluent flow until effluent constituents are settled and stable. |

o We continued to close butterfly valves on the MBR #3 permeate header to determine where our turbidity spikes were coming from
o On 5/4/2021 we had a high turbidity call and found bubbles in the line, this proved to be one of the sources of our turbidity spikes. We re routed the plumbing for our effluent NTU meter and that got rid of the bubbles, but were still getting turbidity spike.
o On 5/5/2021 our turbidity spikes continued so we opened butterfly valve #1 on MBR #3 permeate header which had been closed since 4/19/2021 and also butterfly valve #8 which had been closed since 4/28/2021
o On 5/5/2021 we closed butterfly valve #2 and opened butterfly valve #1, turbidity spikes continued
o On 5/10/2021 we closed butterfly valve #7 which had been closed for several months and we had opened back up in hopes the epoxy repairs we had made had solved that problem. High turbidity spikes over .5 stopped almost immediately with the exception of 1, so we kept that valve closed, but we were still getting small spikes over .25. We kept closing butterfly valves to see if we could locate another problem valve.
o On 5/13/2021 we opened butterfly valve #2 and closed butterfly valve #3, turbidity spikes continued
o On 5/17/2021 we opened butterfly valve #3 and closed butterfly valve #4, turbidity spikes continued
o On 5/19/2021 we opened butterfly valve # 4 and closed butterfly valve # 5, turbidity spikes continued
o On 5/21/21 we opened butterfly valve # 5 and closed butterfly valve #6, turbidity spikes continued
o On 5/25/2021 we opened butterfly valve # 6 and closed butterfly valve #1 because that seemed to help a little last month. Turbidity spikes stopped. |

Turbidity Daily Maximum limit is 0.5 NTU and reported value was 1.8 NTU at EFF-001. |
We determined that our turbidity spikes correspond with MBR #3 coming online, we took the following steps to try and remedy the problem.
o On 4/1/2021 we took MBR #3 offline, drained it down and applied PVC epoxy to all the joints above the membranes. We filled the basin and put it back online on 4/2/2021.
o On 4/8/2021 we tested MBR #3 permeate header for leaks, found one leak applied more epoxy to cover the leak. Left basin offline for the evening to allow epoxy to cure.
o Put MBR #3 back online on 4/9/2021, received high effluent NTU alarm, found no flow at effluent NTU meter adjusted flow and got all the air bubbles out.
o On 4/12/2021 replaced all the sampling tubbing for effluent NTU analyzer
o 4/12/2021 Air bubbles in the effluent NTU sample lines, switched sample pumps.
o 4/15/2021 Replaced Influent tubbing for NTU meter, forgot to place the unit in hold.
o On 4/19/2021 we opened a section of membrane for MBR #3 that had been closed due to previous spikes to see if the epoxy had remedied that problem. That caused a high effluent turbidity spike. Started closing valves to see if we could locate the source of the spikes.
o 4/19/2021 closed first butterfly valve for MBR #3 permeate header.
o On 4/28/2021 closed the corresponding butterfly valve in MBR #3 so both the upper and lower cassettes were isolated.
o On 4/30/2021 we noticed lots of bubbles in the sample lines for the effluent NTU analyzer. Cleaned pump feeding analyzer, replaced hose from the effluent pump to the analyzer, tightened all fitting as much as possible to eliminate air bubbles. |

Order Conditions |
We had a blip in our effluent turbidity of 0.542. Turbidity reading recovered on it''s own. |
The turbidity spikes on the 11th, 12th and 13th we due to a failing effluent analyzer pump we replaced the pump on the 16th after discovering it was failing. We adjusted flow to the effluent turbidity analyzer and performed a manual wipe daily. We also ordered a de-bubbler unit from Hach to go with our analyzer because we believe fine air bubbles coming from our leaking permeate header are causing our turbidity spikes. We have also scheduled a header replacement for MBR #2 on August 12th. |

During the process of cleaning our MBR we divert our plant effluent for the 4 hour flush time and continue to divert our effluent until we have no CL2 residual at our effluent. In the future we will try to take the MBR basin being cleaned offline during hours when an operator is not onsite and put that basin in lead during normal business hours to get more flow through that basin. |
