Control Panel View of a Silica Sol Manufacturing Plant -Automated ED System. Process automation in specialty chemical production is only useful when the control system actually reflects what's happening inside the plant. A display that shows target values without real feedback from sensors is decoration. This image shows the operator interface from a silica sol manufacturing plant commissioned by Laxminarayan Technologies a touch-panel system that monitors live conductivity, flow rate, current density, and pH across the electrodialysis circuit simultaneously. When sodium is being stripped from sodium silicate feed, the rate of removal affects both the final sodium-to-silica ratio in the product and the rate at which colloidal particles grow. Too fast, and silica can aggregate or gel inside the stack. Too slow, and product doesn't meet specification. The control system adjusts current output in response to conductivity readings, keeping the process within the window required for stable colloidal silica formation without an operator manually calculating corrections at each shift. Alarms are configured for conductivity deviation, pressure imbalance between compartments, and flow rate drop the three conditions most likely to indicate membrane fouling or a developing blockage. The system logs operating data continuously, which helps with troubleshooting and supports process optimisation over time. Laxminarayan Technologies builds these plants as complete turnkey systems, including process design, fabrication, control system integration, site commissioning, and onsite operator training. Plants are available at commercial and pilot scale, sized to the client's specific output requirements. https://www.electrodialysis.in/appliction-colloidal-silica-manufacture/ Laxminarayan Technologies H16, MIDC, Gokul Shirgaon, Kolhapur, Maharashtra 416234, India ISO 9001 Certified | Est. 1986
