Shoalhaven Water - Plant Optimisation

"The overall service from HWA (team effort) has again been just what we were after - solid methodology and clear communication" - Simon Groves

The recent plant optimisation project undertaken by Hunter H2O (formerly known as Hunter Water Australia) resulted in improved filtered water quality and filter run times for Milton Water Treatment Plant (WTP).

ops_support_shoalhaven_water_1.jpgThe Milton WTP, located on the NSW south coast and operated by Shoalhaven Water, provides water to the towns of Milton and Ulladulla. The plant operates at 10.5 ML/d capacity and can at times experience events that affect the treatment process. These events can result in the plant becoming unstable and unable to meet targets regarding filtered water turbidity or colour levels.

In August 2013, one such event took place and HWA was engaged. The most probable cause of the event was attributed to a change in raw water quality affecting the treatability of the water, resulting in a large increase in raw water colour and turbidity.

Hunter H2O were able to provide support to Shoalhaven Water and perform jar tests onsite to determine optimal plant dosing configurations. The resulting configurations of these tests were then implemented on the full scale plant.ops_support_shoalhaven_water_2.jpg

Throughout this process, Hunter H2O were able to identify several improvement opportunities relating to chemical selection, applied chemical dose rates, plant configurations and process control targets, The outcome of this project delivered multiple benefits to the customer, including improved filtered water quality and filter run times to comply with operating targets.
