Queenstown Lakes District Chlorine System

The purpose of the Queenstown Lakes District Council chlorine and ancillary equipment upgrade was to improve the chlorination control process at all of the water treatment plants in the Queenstown and Wanaka districts.

Client
Veolia Water

Details

Chemical Feed Solutions won the tender to upgrade and automate the chlorine dosing and water quality instrumentation in the Queenstown Lakes District.

 

The Solution

As part of the upgrade Chemcial Feed Solutions supplied (to each of the 5 water treatment plants in the area) a PLC chlorine control panel. The control panel interfaced with the existing onsite Scada interface to send analytical readings back to the council. The PLC was also programmed to ensure the correct amount of chlorine was dosed.

Pre & Post Reservoir Halosense Chlorine/pH Analysers were used at each site to monitor the Free Chlorine Residuals and pH of the water entering and leaving the plants. Signals were transmitted to the local PLC via RS232 to enable remote monitoring of the water quality.

To enable the water treatment operators to accurately monitor the chlorine levels remaining in the chlorine bottles Chemfeed installed Scaletron 2350 weigh scales. The weight of gas left in each bottle was transmitted to the PLC via a 4-20mA signal to enable remote monitoring of the remaining gas.
