RO/DI system with HMI electrical package
Smith Engineering recently designed a combination 15 gpm Reverse Osmosis/ 30 GPM DI System for Graco’s new French Lake facility in Dayton, Minnesota.
The RO/DI System incorporates a complete monitoring system which is tied to a common UL controls package and GE Versamax micro-PLC. A user-friendly touch screen HMI controls carbon filtration, the RO system, storage tank level as well as all pumps. The HMI electrical package allows System operation to be easily viewed and controlled at one location. An Aquafine OptiVenn Disinfection UV light controls microbial growth in the distribution system.
The purified water feeds approximately sixty-five use-point drops. An axillary distribution pump and controls have been installed mid-Loop for continuously recirculating design and pressure balancing. The Distribution pumps have pressure sensors to maintain Loop pressure setpoints, ramping pumps up or down depending on demand.
The Smith Engineering solution fulfilled the customers need for a Central RO/DI System for full facility process water and provides the ability for process monitoring and control from the existing Building Management System.
