They were also generating high volumes of sludge and incurring high costs to dispose of it. Lab-testing and jar-tests were run to test Hydrex coagulants, which then led to a two-month, full-scale testing to **successfully prove the performance of the program**. Since implementing the Hydrex wastewater chemical program, results show: - A **70% reduction** in sludge generated. - Approximately **250,000€ of annual savings** on their global wastewater treatment cost. - **Full compliance with legislation** in place, including arsenic levels.
