Details: SUMMARY: Review Sodium Permanganate Control System and perform Jar Test training DETAILS: Newport’s water source has a history of seasonal problems with manganese levels. High levels of manganese have manifested in complaints about colored water, ruined laundry, and general customer dissatisfaction with the City’s water appearance and perceived quality. Past engineering studies have recommended the use of sodium permanganate (NaMn04) for the oxidation of manganese in their water. An initial HBH site visit in July with water operations staff reviewed point of chemical application and dosage calculations. The feed system started in August. Further evaluation by the operations staff resulted in a change in the point of permanganate injection from the raw water intake to the flash mixer. A follow up HBH visit was requested to review the online permanganate system, process control criteria, and perform Jar test procedures used to adjust dosage feed rates. I prepared Jar Test Data Sheets and reviewed stock preparation procedures. I made a site visit and reviewed sodium permanganate control systems with operations staff impacts on manganese removal. The system has been very successful in lowering manganese levels in finished water. I discussed the importance of vigilance as the level of manganese in raw water is seasonal, and overdosing of permanganate could create colored water. I held Jar Testing training with the staff to use as a tool to adjust both alum and permanganate dose. ACTION NEEDED: Staff will make contact with HBH if further assistance is needed.
