Details: SUMMARY: Assistance with equipment modifications DETAILS: Warrenton owns and operates a membrane filtration plant. The system has been experiencing problems with HAA5 levels due to organics in their raw water. ACH has been since added to aid in the removal of these organics. This was successful. The city wished to move the chemical feed into the new plant as well as add a streaming current monitor. I visited the city to discuss options for chemical feed and streaming current locations. We also discussed converting problematic soda ash feed to caustic soda. Answered various operational and management questions. ACTION NEEDED: Provide some additional equipment recommendations.
