  • Kraft Foods achieves excellent nutrient removals

    Due to an expansion in potato chip production, the snack food plant required additional wastewater treatment capacity. It needed to be able to meet strict discharge limits for biochemical oxygen demand (BOD), total suspended solids (TSS), ammonia nitrogen (NH3-N), total nitrogen (TN), and total phosphorus (TP) regulations.
  • Leading Texas dairy expands production capacity

    Lone Star Dairy is a leading producer of value-added dairy ingredients derived from locally-sourced milk. While Lone Star Dairy was already enjoying the benefits of low-rate anaerobic digestion, production capacity was driving flows and loads beyond the capacity of their existing system. Upgrades were needed to remain compliant to protect the downstream publicly owned treatment works (POTW).
  • Milton Sewer Authority reduces wastewater strength by 90%

    Settled in 1771 and incorporated into a borough in 1817, Milton is home to approximately 7,000 people in Northumberland County, Pennsylvania, USA.
