In the world of packaging printing, wastewater treatment can often be a bottleneck. One flexographic printing company struggled with time-consuming processes, labor-intensive operations, and inconsistent results.
Its water-based flexographic ink operation generated high-graphic wash water containing metal hydroxides, including copper, along with suspended solids. The existing treatment setup included a sump pit, holding tank, chemical addition, pH adjustment, sludge settling tank, and a plate-and-frame filter press. While effective, the system was slow, requiring several days to treat a single day’s worth of wastewater.
A Smarter, Faster Solution
When the company implemented the Alar® Flex-O-Star®, an industrial wastewater pretreatment and sludge dewatering system, the transformation was immediate. The new setup processed a full day’s wastewater load in under five hours—a dramatic improvement over the previous multi-day cycle.
Thanks to the integration of the Alar® Auto-Vac™ Rotary Vacuum Drum Filter, the system also produced dry, landfill-ready solids, reducing waste handling costs and simplifying disposal.
Proven Long-Term Performance
Encouraged by the results, the company installed more than four Alar Flex-O-Star units across multiple facilities over the next decade. Each installation brought consistent improvements: reduced labor, higher throughput, and more reliable water treatment performance.
This case demonstrates how the Alar Flex-O-Star technology helps industrial printers achieve efficient, sustainable, and cost-effective wastewater treatment—all while supporting production demands and environmental goals.
