Secure automation on filter controls.

A case study describing how the City of Hot Springs, Arkansas (USA) has implemented Bedrock Open Secure Automation (OSA) technology for water filtration modernization is now available. Bedrock OSA has provided Hot Springs an open, secure control platform, which Brown Engineers, of Little Rock, Arkansas, integrated across the City’s existing Ignition SCADA software, leading to dramatic performance improvements.

“The City projected that the nine filters that were currently operating on its main water treatment plant would not be adequate to handle increasing demand. We replaced the antiquated PLCs with modern Bedrock control functionality on six of the filters. We had already installed a communications gateway based on Inductive Automation’s Ignition SCADA software and it was just a matter of creating a hierarchy of control objects, which we did easily using Bedrock’s IEC 61131 integrated engineering environment,” said Brown Engineers principal, Dee Brown.

The project improvement in the automatic backwash process significantly helps conserve water, improves water quality, and initiates collection of filter data needed for extending regulatory run-time limits. And because cyber security is built into the Bedrock OSA control system, the new controls were protected by industry-leading intrinsic cyber security – at no additional cost.

Well-documented results show how the six upgraded controls perform consistently, as if they were a single unit, while performance of the three remaining filters varies wildly, with flow rates varying from 1400 to more than 2000 GPM. Download the fully-illustrated case history here.
