SP HOLDINGS (PNG) - ACTIVE CARBON FILTER
Job No: #4306
SP Brewery commissioned MPA Engineering to develop an automatic control system for the activated carbon filter unit at their Gordon’s Brewery in Papua New Guinea.
The activated carbon filter is an integral part of the water treatment process; it removes free chlorine and reduces the amount of organic substances in the incoming water. Ensuring integrity and purity of water is
critical in the brewing process, to both the quality control procedure and also to the final flavour of the beer. The MPA engineered automation process controls the three different operational stages of the activated carbon filter - Service, Backwash, and Sterilization using a Siemens S7-226 PLC and SMC Pneumatics. Together these products allow maximum flexibility, and operator adjustment of the system via an easy to use Siemen's TP 070 Touch Panel. MPA provided extensive support to SP Brewery for this project. This included, the expertise necessary to select appropriate PLC hardware, HMI Interface and Pneumatic hardware, the skills to supply and program electrical hardware, the design and manufacture of the stainless steel enclosure to house the automation equipment and complete software documentation.
The newly designed system provides a simple, economical solution to SP Brewery requirements, while offering a number of benefits, which include:
•Consistent bacteriological quality of the water; due to the precise automatic control of the operational stages of process.
•Reduced water usage; due to the precise control of the valves during different modes of operation.
Automating the process has also increased the operators' productivity, by enabling them to continue with other work instead of manually overseeing the operation of the carbon filter.
