Figure No. 1. - Iron Removal Treatment System Basic Process Flow
The system design included the use of the existing water treatment equipment as well as a layout design for integrating the new equipment in the limited space of the existing well house building. Figure No. 2 shows the recommended equipment layout.

The chemistry behind the water treatment design starts with the basic chemical reaction of Ferrous Iron (Fe
+2)to Ferric Iron (Fe
+3). The sodium hypochlorite (NaOCl) chemical injection oxidizes the Iron from the dissolved Fe
+2 state to a precipitated Fe
+3 state, allowing for filtration.
The design included retention tanks to allow for an extended reaction time to fully precipitate the Iron prior to filtration. Following the 20-minute retention time, the precipitated Iron is filtered-out via three (3) multimedia depth filters. The filters were designed with five (5) media layers of filtration plus a base gravel layer, as shown in Figure No. 3.
The MMF's were installed in parallel form, to insure a full instantaneous supply to the distribution lines.

The full system design, installation, disinfection, and start-up procedures were reviewed and approved by the Ohio EPA. All project details were completed to meet the Recommended 10 State Standards as well as the AWWA Standards for Safe Drinking Water, as required by the Ohio EPA.
An additional service IFM provided during this project was assistance with the preparation and submittal of the Permit to Install (PTI) application with Ohio EPA. This PTI is to receive approval of the water treatment equipment addition to the existing Public Water System (PWS). With the coordination between IFM's Engineering Department and Operational Services Department all required operational details and submittal documents were completed and answered through one source.
This availability along with IFM's standing rapport the OEPA availed the opportunity to complete a system upgrade through a streamline process.
Upon OEPA approval of the PTI, IFM delivered and installed a turn-key water treatment system in the existing well-house building. A continuous water supply to the facility was maintained during the installation and all equipment was disinfected prior to placing the new system online. Onsite operational training of the equipment was included with the project package.
Following the installation and system start-up IFM was further contracted to help the campground complete the
OEPA required Seasonal Non-community Public Water System Annual Start-Up Certification. This certification checklist is required by the Ohio Administrative Code Rule 3745-81-51 and must be submitted to the Ohio EPA prior to providing water to the public each opening year.
IFM continues to take service calls to the system and collect the Total Coliform samples, as required by the Ohio EPA PWS facility specific Chemical Monitoring Schedule.
